A Study On The Sky X Devices

A Study On The Sky X Devices In todays worlds Connectivity is the most important thing. No matter where ever we are we need to keep ourselves connected with the world to keep ourselves updated. The world around us is changing at a rapid pace so if we dont keep up with it we would be left behind. One of the prime way by which we do this is internet. But there are places where Internet is not available. There are few places where due to terrestrial location or other reasons the internet availability is not possible or its prohibited. In todays world we feel like sharing whatever we can on the network, we share a lot of data on the network. We keep uploading the Videos on Youtube. We keep on adding our photo on the networking websites. Day by day our need for the bandwidth is increasing as our need to share and upload the data keeps on increasing. Here comes an option for this also its the communication using the satellites. The Geo-stationary satellite orbiting at an altitude of 36,000 kms can be used for this. Satellites can be used to carry our data traffic and they could be used to communicate with each other. But the problem with it was that the prevalent TCP protocol at that time did not have enough of technology advances to overcome the disadvantages of satellite communication as compared to its advantages. So the SKY-x technology was introduced, it provided a secure and fast way to transfer data through satellite. It was totally transparent to the users. In place of tcp protocol it used a new XTP protocol (Xpress Transport Protocol) .This new Protocol is optimize for the data transfer over Satellite. Problem with TCP: The data transfer using satellite is facing various problems like large latency rate and high Bit error rate with the Asymmetric design of the bandwidth of all satellite. Satellite is one of the best options in the upcoming days to communicate and transfer data. But there did not exist proper standards or Protocol for the transfer of the data. The currently used TCP Protocol was not optimized for the transfer of data over Satellite, due to which the High bandwidth provided by the Satellite mostly goes unused. This also reduces the throughput of the satellite transmission. So we were not able to fully utilize the benefits provided by the Satellite transmission. Where as the Satellite transmission was more prone to bit error caused due to the environmental changes. The TCP Protocol was designed so that they can give high performance and large throughput over local area network.TCP protocol had various feature for LPV6 which were specialized for the Optical fiber network. So network setup of Optical cables and using the TCP protocol were far more reliable and cheaper than transmission using TCP protocol over satellite. All the benefits which are incurred over the cable network by TCP Protocol are lost on the satellite transmission. TCP had a congestion avoidance algorithm/mechanism which were not suited for satellite transmission because satellite transmission had a long round trip. This long round trip was misinterpreted by the TCP as congestion and hence it reduces the transmission rate. This resulted in the wastage of the bandwidth provided by the Satellite transmission. Hence the Congestion avoidance algorithm used by the TCP is also a big problem in the Satellite transmission. The WINDOW SIZE Problem: The TCP protocol utilizes a sliding window mechanism to limit the total amount of data to be transfer over the network. When the window become full, the sender stops sending the data anymore until it receives the acknowledgment signal from the recevier.As the back channel speed is less on satellite using tcp protocol its very difficult to transfer data on satellite, So to avoid this TCP statically fix the size of window to 100 kb over the T1 satellite, which limits the total amount of bandwidth which we can use as compared to total provided by the satellite. Moreover many of the operating system uses a window size of 8 Kb which only provides us with a speed of 128 kbps per connection, which is very less as compared to bandwidth available over satellite. Thus window sizing mechanics reduces the transfer of the data over the Satellite. While the SK-x technology dose not use a fix window size of 8 Kb it uses the performance enhanced size of the window thus allowing us to fully utilize the bandwidth provided by the Satellite for the data which can be compressed SKY-x technology provides a better throughput rate than the simple cable network. Thus the SKY-x technology is much better than the TCP Protocol for the transfer of data over the satellite. SKY- x Technology: The SKY-x technology was developed by one of the worlds leaders in TCP/IP Protocol developer Mentat.The SKY-x technology Products replace the TCP protocol product to transfer data over Satellite. These Products are transparent to Users they behave the same way as the TCP Protocol product and they provide more security and Less Latency time while giving high throughput over satellite. It consists of SKY-x Gateway, SKY-x Client/Server, SKY-x OEM Products. The SKY-x gateway works in the same way as the TCP Gateway except that the Sky-x gateway intercepts the TCP signal and helps to convert it to the SKY-x protocol so that it can be used to transfer over the satellite. The SKY-x client are the same except that they need to be installed on the pcs of the local user to help them to connect using satellite. The SKY-x technology Protocol replaces the TCP Protocol used on Optical Fiber for the use on the satellite. Adding the SKY-x products into the network helps the user to efficiently use the full bandwidth provided by the satellite. The SKY-x products enhances the performance of the network transparently with out needing to change any thing over the client side or the server side. The SKY-x product increases the overall performance by thrice, while increases the files transfer by 10 to 100 times over the satellite. This product are enhanced version of the otherwise known TCP Performance enhancing (TCPPEP) Or the Satellite spoofer. The XTP protocol used was developed by the XTP forum a non profit organization. The SKY-x products divide the normal TCP connection into three different components: 1. The connection between the TCP client and the SKY-x gateway on the remote side of the network. 2. The Connection between two SKY-x gateway involving XTP protocol for the transfer of the data over the Satellite. 3. The Connection between the SKY-x Gateway and the TCP server on the other side of the network. Unicast versus Multicast: The fiber optic network used the unicast data transfer to send the data to all the clients it used to send the same copy of data to all the clients which a bit time consuming and waste a lot of bandwidth of the network. While the Unicast was not good for the satellite network. But the only multicast protocol available was UDP based. This UDP based protocol did not involve any method to detect the error in data transfer and to check the re-transmission of the data over the network. It even does not provide any mechanism to re-sequences the data packets sent over the network. This problem was overcome by the SKY-x multicast. It provides a reliable and secure way to multicast the data over the satellite. It provides fast efficient, reliable multicast file transfer. Any data that is lost or corrupted during the transmission is re-transmitted, providing transfer reliability rendering the special FEC software as a unnecessary thing. The SKY-x multicast fan out is an important part of the SKY-x Gateway. It transparently converts the TCP unicast data to the SKY-x multicast data. The SKY-x gateway can transfer the file to every remote location with just one multicast. As the SKY-x multicast is transparent to the user any device can transfer the data using the Multicast no matter whatever operating system it has without needing any special software. Below is a graph showing comparison between Unicast traffic and Multicast traffic: As shown in the graph Unicast transmission increases the traffic of the network considerably, whereas using multicast for the same no of users the traffic is 18th of the Unicast transmission. Thus the SKY-x technology also reduces the traffic over the high bandwidth Satellite Network. Thus SKY-x technology has overcome each and every Limitation of the TCP protocol hence providing us with an efficient way to connect using the Satellite. SPEED TCP versus SKY-x: The new technology used in the Sky-x products increases the performance as well as the speed of the network. The SKY-x products use a Fast start feature which enables it to establish new connection at a very fast speed. The HTTP Benchmark by the WEB Stone shows that for an 8 Mbps line having 50 simultaneous connections using a SKY-x gateway has an average response time of 0.7 to 1.1 sec which is much lowered as compared to the 3 sec time on a network using TCP protocol. Increased Throughput: The Sky-x Technology provides a high bandwidth even at a high bit error rate. It does so by compressing the data transmitted over the network. For a 10 Mbps satellite the TCP protocol is able to provide a small bandwidth of 1.5 Mbps while at an error rate of 1* 10-5 its bandwidth drops to as low as 0.03 Mbps. While on the other hand even at the above mentioned error rate the SKY-x products maintains a bandwidth of 5.8 Mbps when the data is not compressible, if the data is compressible it maintains a bandwidth of 15.1 Mbps. THE SKY-x Architecture: The SKY-x products or network have a SKY-x Gateway installed into the system. This gateway provided by the SKY-x helps to make the network transparent to the user, it transparently intercepts the TCP protocol transmitted by the user and convert it into the XTP (Xpress Transport Protocol) which is optimized for the Satellite transmission. Then on the other side it converts back the XTP protocol into the TCP protocol for the Server. So the client and the Server side in the Network remain unaware to all this translation. It requires no special change to be made on the part of the client or the Server in the Network, so all the applications the Program which were used previously keeps functioning on this network also. The XTP protocol also supports the TCP congestion avoidance algorithm to keep the terrestrial network stable and protected. The two Sky-x Gateway pass the data between each other as if there doesnt exists any intermediate link between client and the server. XTP protocol also provides a functionality called as Web pre-fetching. The Web Pre-fetch is used to fetch all the embedded objects in a web page whenever a client sends a request for even a simple html page. Then these embedded objects are made visible to the client as and when it is requested by the client thus avoiding the fetch time required for fetching it from the satellite. Thus the XTP protocol not only provides the security stability on the satellite network but it also considerably increases the speed of data transfer by using the Web Pre-fetch. XTP also provides an Accelerator which helps in speeding up the network traffic. It accelerates the XML and HTTP sessions, database synchronization as well as the transfer of the file Large or small between the client and the Server. Thus it helps in providing a better response time and throughput of the network. It also helps in speeding up the Database backups. It minimizes the re-transmission of data required due to error in it or due to the loss of data. Thus it also helps in the use of Satellite as a communication medium. SKY-x Products: Mentat was the first company to build a product having the sky-x technology. Mentat is leader in developing the products based on the TCP/IP protocol. Renowned Companies like Apple, IBM, Motorola, and Sony depend on the TCP/IP network software provided by Mentat. It launched various product named Mentat SKY-x XR10 Gateway. Mentat SKY-x XH45 Gateway. Mentat SKY-x XH155 Gateway. These products built by Mentat had the in built Accelerator to speed up the network traffic. The XR10 is designed to be used for the satellite which provides a link of 10 Mbps. Or it could also be used in combination with the other Mentat products like the XH45 which supports higher bandwidth links. The XH45 is designed for the satellite providing the link of 45 Mbps or it can also be used as a hub in a network having XR10 products. In the Same way Mentat also provides the SKY-x servers as SS10 SS45. The SKY-x SS10 server is used in the network having 10 Mbps links. While the SKY-x SS45 server is used in the network having the 45 Mbps links. Packeteer Mobiliti Technology: Packeteer is the Global Leader in Wan Application Optimization. In Todays World the users should be able to work from wherever there business demands. On the other hand the Companies should also provide their workers with the facility like LAN no matter wherever they are or they would be at a risk to lose many chances to carry out their business successfully. Packeteer came forward with a solution to this by integrating the SKY-x technology into its Mobility software. So the user can access the LAN from the remote location using there Desktops and Laptops. This Mobiliti software supports TCP file transfer automatic backup. It caches or saves the recently used document on the client side so as that the user can access them whenever needed even if the server is not available. This software is available in various languages like German, French, Chinese and Japanese. It also automatically configures the my document folder also provides and option to choose the location to store the recently used file by the user. Conclusion: Thus the new SKY-x technology is better than the TCP Protocol for Satellite transmission. The Sky-x Technology provides a large bandwidth as well as a fast data transfer on the satellite network. It has removed all the limitations which existed in the use of TCP for satellite transmission. Thus the SKY-x technology has opened a new horizon in the way we used to communicate with each other. Now we can use the Satellite as the medium of communication and remain connected with each other even at the most remote places on the earth. And this new SKY-x Technology also comes as a savior to us for our daily increasing bandwidth requirements. It provides a large bandwidth to transfer data on the network. Thus now we can connect to more places and also share more Data on the network.

Art and Literature in MacLachlan’s Arthur For the Very First Time and Arnold Lobel’s Frog and Toad Together :: Compare Contrast Comparison

Art and Literature in MacLachlan’s Arthur For the Very First Time and Arnold Lobel’s Frog and Toad Together When it comes to an artist, the perspective of the environment will be very different from individual to individual. This leads to the difference in technique and style When art and literature are put together the picture adds to the words and shows what the literature is describing, rather than just something to look at. Although Lloyd Bloom’s illustrations of MacLachlan’s, Arthur For the Very First Time and Arnold Lobel’s, Frog and Toad Together can not compare to the famous Leonardo, the art in each is very unique. Bloom gives very sharp, detailed drawings, almost like a photo, where as Lobel gives loose, cartoon like drawings. These two books are very different in terms of reading level, which allows Bloom to create more detailed and real life drawing, where as Lobel can get away with a less life orientating, rounded picture, almost like a cartoon. Bloom’s illustrations stay consistent throughout the book with vibrant, life oriented drawings. The black and white, pencil drawn pictures, create almost an exact replica, like a photo, for an older audience which leaves little to the imagination. In the book there is a picture of two children sitting by a pond. There is so much detail in the picture that you can see underneath the water if you look hard enough, along with both children’s reflection in the water. There is an incredible amount of detail which is put together by small amounts of shaded sections and very fine touches of the pencil. This all brings the realism of the picture in order. Realism shows through when the text is read. This book is fiction but very well could be non fiction. It isn’t a pretend book, there aren‘t people with blue hair or even frogs that talk. The amount of detail in the book’s words go along well with the amount of detail in the pictures. The pictures bring and add to the real life situations of the story, and complement the realism of the words. Lobel’s pictures in comparison, are poor drawings and weak in technique. They lack specific detail , like small markings and create an overall round picture. This book was intended for an audience of grades 1-3, much different from the upper level MacLachlan book. Its use of colors and earth tones are dull.

Internet as a Threat to Old Media

Broadcasting internet as a threat to old media Introduction Just a few clicks on the mouse and a whole world of information are available for free. The internet, whilst largely contributing to declining newspaper, magazines and books sales, decreasing the percentage of advertising on TV and radio, increasing of internet piracy and illegal downloading of films and music. Internet can at least provide a huge resource for journalist, authors, musicians, photographers, producers, editors, directors and all information workers.On the other hand, audiences and users of media mainly still believe on old media as they gain their information and follow latest news (which affect public opinion) from old media because they trust it and rely on its credibility when they compare it with internet . they thought that internet is the world of rumors. http://technorati. com/technology/it/article/do-you-see-the-internet-as/#ixzz16VrHKY7B Background Books writing with words was invented by the Sumerian s (southern Iraq) about five thousand years ago (c. 3100 BC). As far as we know it derived from symbols used for the keeping of accounts around four hundred years earlier.At first, writing was restricted to inscriptions, e. g. on stone, seals, brooches, and containers. The Sumerians then developed baked clay tablets, which can be regarded as the first books. These were soon followed by the papyrus rolls of the Egyptians, made from a plant native only to the Nile Valley. The traditional modern form of the book is called the codex. Meanwhile paper was invented in China as early as 105 AD, and was at first prepared from bark and hemp. This paper developed to a high standard, and paper-making later spread to Japan (c. 10 AD), and then to the Arab world along the Silk Road, via Samarkand in Central Asia. The Arabs introduced paper into Europe via Spain. Printing Printing was another Chinese invention. However such cast type did appear in Korea before developing quite independently in Eur ope. A major advance in the West was Johannes Gutenberg's printing from cast metal type (c. 1450 AD). However this was still hand composed on a mostly wooden press. This still relied on human power to operate. A steam-powered press invented by the German Friedrich Koenig followed in 1810.An American, Richard Hoe, invented the faster rotary press in 1846. Printing raced further ahead when the mechanical composition of type was perfected in 1886 with the Linotype compositor. Lithography was long used to print pictures for books. From this method came the idea for offset printing – in 1904 the first offset press appeared. In offset printing the method of â€Å"relief† printing from cast metal type, traditional since Gutenberg, is replaced by a smooth photographic plate. By 1980 offset printing was taking over from the older method in many countries. That was only the beginning of the modern printing revolution.From 1968 computers became involved in printing (the Linotron) . In 1983 the offset plate progressed to a format involving the laser-beam transference of stored digital information. Gradually printing worldwide became a digital and computerized process, and mechanical printing began to disappear. The Digital Revolution This change led to the irony that a series of advanced digital electronic processes now produced the traditional analogue material book. It was only a matter of time before the logical conclusion would be drawn – that books could exist in a purely electronic form.Moreover such books could incorporate new possibilities undreamed of in the printed codex book. For example, they could be instantly updated, be searchable electronically, include sounds ; video and even a dictionary, and interact directly with the new Internet, and therefore contain instant links to further information. The advent of digital book files also meant that traditional physical books could now be printed individually as required from a stored computer file (Print on Demand, or POD), rather than in the traditional large print runs.This meant both that books could be cheaper in general, and that it was financially practicable to print them in limited numbers for a more restricted readership than before. So rather than immediately displacing the printed codex, the advent of the digital book meant that the physical book could now flourish as never before. At the same time this change prepared the ground for a decisive future shift towards electronic reading. Dawn of the e-Book The electronic book (e-book), existing as a virtual entity stored in a digital file, began to emerge in its own right in the last years of the twentieth century.Like many new technologies it suffered from technical teething troubles, ineffective or inappropriate marketing, commercial rivalries that slowed its progress, and initial public scepticism or indifference. Gradually however the electronic book became capable of being read from an increasing variety of devices, and its vast potential began to be more widely understood. It became clear that the e-book would represent the next leap forward in the onward march of the book. While it can simply represent traditional texts it can also become a layered and interactive multimedia experience.Indeed the book of the future could even be spontaneously assembled from multiple sources for specific educational or entertainment purposes, by a single reader or group. The e-book therefore holds the promise of adding an unprecedented degree of flexibility to the concept of the book. The book is one of humanity's most enduring cultural artifacts and treasures. As it evolves, the greatest threat to its future is therefore not from technical advances but from the danger of new generations losing the inclination to read.The ability to read and write is our greatest tool in education, and, apart from the family, the single most important medium existing for the transmission of ideas and the continuance o f an evolving human culture. http://www. e-book. com. au/bookhistory. htm Newspapers â€Å"Were it left to me to decide whether we should have a government without newspapers, or newspapers without a government, I should not hesitate a moment to prefer the latter. † -Thomas Jefferson, 1787. The history of newspapers is an often-dramatic chapter of the human experience going back some five centuries.In Renaissance Europe handwritten newsletters circulated privately among merchants, passing along information about everything from wars and economic conditions to social customs and â€Å"human interest† features. The first printed forerunners of the newspaper appeared in Germany in the late 1400's in the form of news pamphlets or broadsides, often highly sensationalized in content. In the English-speaking world, the earliest predecessors of the newspaper were corantos, small news pamphlets produced only when some event worthy of notice occurred.The first successively publi shed title was The Weekly Newes of 1622. The first true newspaper in English was the London Gazette of 1666. Fo In America the first newspaper appeared in Boston in 1690, entitled Publick Occurrences. Published without authority, it was immediately suppressed, its publisher arrested, and all copies were destroyed. The first successful newspaper was the Boston News-Letter, begun by postmaster John Campbell in 1704. Although it was heavily subsidized by the colonial government the experiment was a near-failure, with very limited circulation.Two more papers made their appearance in the 1720's, in Philadelphia and New York, and the Fourth Estate slowly became established on the new continent. In 1783 there were forty-three newspapers in print. The press played a vital role in the affairs of the new nation, representing all shades of political opinion. The ratification of the Bill of Rights in 1791 at last guaranteed of freedom of the press, and America's newspapers began to take on a ce ntral role in national affairs. Growth continued in every state.In the Jacksonian populist 1830's, advances in printing and papermaking technology led to an explosion of newspaper growth, the emergence of the â€Å"Penny Press†; it was now possible to produce a newspaper that could be sold for just a cent a copy. Previously, newspapers were the province of the wealthy, literate minority. This sudden availability of cheap, interesting reading material was a significant stimulus to the achievement of the nearly universal literacy now taken for granted in America. In the 1850's powerful, giant presses appeared, able to print ten thousand complete papers per hour.At this time the first â€Å"pictorial† weekly newspapers emerged; they featured for the first time extensive illustrations of events in the news, as woodcut engravings made from correspondents' sketches or taken from that new invention, the photograph. Reporters, called â€Å"specials,† became the darlings of the public and the idols of youngsters everywhere. Many accounts of battles turned in by these intrepid adventurers stand today as the definitive histories of their subjects. Newspaper growth continued unabated in the postwar years. By the 1890's the first circulation figures of a million copies per issue were recorded.At this period appeared the features of the modern newspaper, bold â€Å"banner† headlines, extensive use of illustrations, â€Å"funny pages,† plus expanded coverage of organized sporting events. The rise of â€Å"yellow journalism† also marks this era. This is also the age of media consolidation, as many independent newspapers were swallowed up into powerful â€Å"chains†; with regrettable consequences for a once fearless and incorruptible press, many were reduced to vehicles for the distribution of the particular views of their owners, and so remained, without competing papers to challenge their viewpoints.By the 1910's, all the esse ntial features of the recognizably modern newspaper had emerged. Radio and television have gradually supplanted newspapers as the nation's primary information sources, so it may be difficult initially to appreciate the role newspapers. Not complete http://www. historicpages. com/nprhist. htm, Phil Barber, 03/08/2010 Magazines The term â€Å"magazine† is generally acknowledged to have come into usage with the publication in the 1730s of the Gentleman’s Magazine by Edward Cave. Its aim was to entertain with stories of crime and romance.It soon proved popular, not just for sale but for rental in public houses, coffee houses and barber shops. Magazines were more affordable than newspapers because printing technology allowed mass production. Taking their cue from America, British publishers produced all-fiction magazines such as Romantic Confessions and similar ‘penny dreadfuls’. General interest magazines such as Answers, Titbits (Tit Bits from all the Most In teresting Books, Periodicals and Contributors in the World), Home Chat, Comic Cuts and Pearson’s Weekly were also hugely popular. The early 20th century saw new styles of magazine such as Reader’s Digest hich included edited versions (digests) of articles and stories. International editions followed the same formula, later developing subscription as a means of ensuring a place in the competitive magazine market. â€Å"Life† magazine which traded on the quality of its pictures in a period when photography was accepted as an art form and photojournalism was regarded as a means of social commentary. â€Å"Life† used the slogan: ‘To see life, to see the world; to witness great events; to watch the faces of the poor and the gestures of the proud; to see strange things’.It had many imitators (or, perhaps more kindly, admirers) such as Picture Post and Illustrated in Britain and Paris Match and Stern in Europe. The end of the Second World War saw ne w titles emerged to satisfy the needs of increasingly affluent consumers who now had business and technical interests as well as expanding leisure pursuits. Interestingly, the emerging broadcast media – particularly television – were accommodated by the magazine industry that began to produce publications which included listings, reviews and background material.Later spin-offs would include comics based on television characters, and magazines dedicated to specific topics or programmes such as BBC Wildlife and Gardener's World. A web search will reveal the extent to which the big companies have other interests, particularly media interests other than publishing magazines. The Guardian Media Guide contains details of the sites run by all the main players in the publishing business. Ezine is an electronic newsletter or magazine. Ezine could reside on a website, intranet system or be sent throughout any network, including the largest network; the Internet.The key to succes s for the big companies is the advertising revenue generated by magazines, and the ability of specific interest magazines to provide clearly-defined target audiences. Not that there is complete freedom to publish any material that will make money: there are laws and regulations that affect magazines just are there are for other media forms. 2000 The Media Guide edited by Steve Peak and Paul Fisher (Fourth Estate) 2001 The Media Guide edited by Steve Peak and Paul Fisher (Fourth Estate) EzineArticles. om Lance Winslow, Expert Author , 18 Jul 2006 A decade on the streets Simon Rogers and Xan Brooks, in Media Guardian September 10 2001 http://www. mediaed. org. uk/posted_documents/Magazines. html Radio Radio owes its development to two other inventions, the telegraph and the telephone, all three technologies are closely related. Radio technology began as â€Å"wireless telegraphy†. It started with the discovery of â€Å"radio waves† – electromagnetic waves that hav e the capacity to transmit music, speech, pictures and other data invisibly through the air.Many devices work by using electromagnetic waves including: radio, microwaves, cordless phones, remote controlled toys, television broadcasts, and more. Guglielmo Marconi, an Italian inventor, proved the feasibility of radio communication. Radio-telegraphy is the sending by radio waves the same dot-dash message (morse code) used in a telegraph. Transmitters at that time were called spark-gap machines. It was developed mainly for ship-to-shore and ship-to-ship communication. Lee Deforest invented space telegraphy, the triode amplifier and the Audion.In the early 1900s, the great requirement for further development of radio was an efficient and delicate detector of electromagnetic radiation. The result of Lee DeForest's work was the invention of amplitude-modulated or AM radio that allowed for a multitude of radio stations. Online radio streaming was born in the 90s as a solution for the music industry to reinvent itself or as a solution for activists. WXYC is the first traditional radio station to announce broadcasting on the Internet. The term internet radio isn't just about live streaming on the internet but can also be an archive site with audio files.Online radio can be a terrestrial radio station that broadcasts to a bigger market, or an independent internet-only operator that is just starting. Web radio stations are a good solution for new markets, delivering independent music that listeners can't hear on regular radio. The advantage of internet radio services is that its services are usually accessible from anywhere in the world. Internet radio is distributed most often via streaming, in audio formats like mp3, Ogg Vorbis, Windows Media Audio, RealAudio and others. http://www. radiobunch. com/online-radio-history. html, http://inventors. bout. com/od/rstartinventions/a/radio_2. htm , Mary Bellis Television In the late 1800s, Paul Gottlieb Nipkow, a student in Germ any, developed the first ever mechanical module of television. He succeeded in sending images through wires with the help of a rotating metal disk. This technology was called the ‘electric telescope’ that had 18 lines of resolution. In 1923, an American inventor called Charles Jenkins used the disk idea of Nipkow to invent the first ever practical mechanical television system. From 1926 till 1931, the mechanical television system saw many innovations.Although the discoveries of these men in the department of mechanical television were very innovative, by 1934, all television systems had converted into the electronic system, which is what is being used even today. In 1927, Philo Taylor Farnsworth was able to invent a working model of electronic television that was based on Swinton’s ideas. His experiments had started when he was just a little boy of 14 years. By the time he became 21, Philo had created the first electronic television system, which did away with th e rotating disks and other mechanical aspects of mechanical television.Thus was born the television system which is the basis of all modern TVs. In 1948 there were early tests of cable television in the rural area of Lansford, PA. In 1956 the Ampex quadruplex videotape replaced the kinescope; making it possible for television programs to be produced anywhere, as well as greatly improving the visual quality on home sets. In 1957 the 1st practical remote control, invented by Robert Adler and called the â€Å"Space Commander,† was introduced by Zenith.. This â€Å"Golden Age† of television also saw the establishment of several significant technological standards.These included the National Television Standards Committee (NTSC) standards for black and white (1941) and color television (1953). In 1952 the FCC made a key decision, via what is known as the Sixth Report and Order, to permit UHF broadcasting for the 1st time on 70 new channels (14 to 83). This was an essential decision because the Nation was already running out of channels on VHF (channels 2-13). That decision gave 95% of the U. S. television markets three VHF channels each, establishing a pattern that generally continues today.Thus the â€Å"Golden Age† was a period of intense growth and expansion, introducing many of the television accessories and methods of distribution that we take for granted today. 1962 brought the 1st transatlantic reception of a television signal via the TELSTAR satellite. High definition television (HDTV) was also introduced during this period. In 1981 NHK, the Japanese National Broadcasting company, demonstrated their 1,125 line HDTV system to the Society of Motion Picture and Television Engineers at their Winter conference in San Francisco.In 1994 HDTV standards were established and a plan for the transition from analog to digital transmission of television programming has been rolled out throughout the decade.

The 1956 Dartmouth Artificial Intelli gence conference crystallized the concept that technology was improving at an exponential rate, and provided the first serious consideration of the consequences. †¢Marshall McLuhan made the idea of a global village interconnected by an electronic nervous system part of our popular culture. In 1957, the Soviet Union launched the first satellite, Sputnik I, triggering US President Dwight Eisenhower to create the ARPA agency to regain the technological lead in the arms race.ARPA appointed J. C. R. Licklider to head the new IPTO organization with a mandate to further the research of the SAGE program and help protect the US against a space-based nuclear attack. Licklider evangelized within the IPTO about the potential benefits of a country-wide communications network, influencing his successors to hire Lawrence Roberts to implement his vision. A special computer called an Interface Message Processor was developed to realize the design, and the ARPANET went live in early October, 196 9.The first communications were between Leonard Kleinrock's research center at the University of California at Los Angeles, and Douglas Engelbart's center at the Stanford Research Institute. The first networking protocol used on the ARPANET was the Network Control Program. In 1983, it was replaced with the TCP/IP protocol invented Wby Robert Kahn, Vinton Cerf, and others, which quickly became the most widely used network protocol in the world. In 1990, the ARPANET was retired and transferred to the NSFNET.The NSFNET was soon connected to the CSNET, which linked Universities around North America, and then to the EUnet, which connected research facilities in Europe. Thanks in part to the NSF's enlightened management, and fueled by the popularity of the web, the use of the Internet exploded after 1990, causing the US Government to transfer management to independent organizations starting in 1995.

What Three Qualities Do You Think Are Most Necessary for a Good Parent

Nowadays people say that not everyone is capable of upbringing a child. Parenthood, which used to be a natural status for almost anyone, is now the source of long debates among couples and a very profitable field to writers and publishers. First of all, a good parent should be a good listener, a person who understands what his or her child needs. Parents that listen are supportive people who put aside their high expectations and will keep their ears open for their young offspring, ready to advise no matter what. Secondly, patience must characterize every person who is bringing up children. That means that we must be ready to forgive the mistakes of the inexperienced , young children and that we must help them not with violence , arguing and patronizing but by drawing the line, setting the right example and being steady and consistent. Finally, I believe that parents ought not to consider their children as an expansion of themselves. They should not be egocentric and they should find the courage to accept their children’s choices and reactions not as a battle but as if their children are showing them the way to how to be a better parent, teaching them the important values of equality and mutual respect. In conclusion, I think that to be a parent is a life-changing experience and a huge responsibility. After all, the children of today are the parents of tomorow and they should be given the right example to follow later at life. Thalia Procopiu Director of Studies 2011, Greece

Amateurism in Ncaa football Essay Example for Free

Amateurism in Ncaa football Essay The National Collegiate Athletic Association is corrupted with sneakiness, unfairness and greediness, particularly in division one colleges. In North America, sports play a huge role, especially sports like football, hockey, basketball and baseball. Sometimes this causes us to become vanished of fairness, like are the players being treated right? A great example of injustice in sports is amateurism of football players in division one colleges. Division one and division two athletes must obtain amateurism, which is playing the sport as a hobby rather than for the money, many would define amateurism as worthy but it is really tainted and monopolized! Should NCAA athletes get paid? Numerous of people would easily answer no because college athletes are on scholarships and various athletic departments loses money even with a winning record. Also college athletes have advantages with free tuition, books, living expenses, food, clothing and health. Although all of these features appear wonderful but there are more cons than pros of amateurism. For example the NCAA is a business that are making money out of these athletes basically for free and yes they do receive tuition but that does not compare to the large amount of money the NCAA is making out of them. According the Stanford Review, college athletic is a multimillion-dollar industry with recruiting the best of the best in the nation. So why not pay the best of the best, if they put in all this hard work, then they should be rewarded. Instead the National Colligate Athletic Association is a monopoly because of its limitation of scholarships and other payments to boost its college sports program. Also not all of the athletes receive scholarships. College football players put in more work on the field than they do in the classrooms. For example when in season they have five-hour practices and that doesn’t include lifting for an hour and this is from Tuesday to Friday with game day on Saturday. After the season is over then they begin spring ball which is just only practices and plus they don’t have a summer break because they have to stay for summer ball. We consider college athletes as student athletes but that is such an oxymoron because in realty their sport does come before their schoolwork. When playing in a big division one school, most athletes believe to make it in the big leagues but sadly only about 2% makes it. Colleges should stress more on education for so call student athletes but they don’t because of the athlete’s popularity and how the NCAA is making money out of them regardless if they have a future afterward or not. It’s horrible how the NCAA contract includes that when an athlete commits and decides to transfer to play for another school then they have to sit out a year. This rule is so unfair because coaches don’t have to do that. The NCAA is the biggest monopoly in America according to Bloomberg Businessweek Magazine. When selling college souvenirs and jerseys, videogames, etc and the athlete does not make any money from that, even if they are the main reason for those sales. It is amazing that most players receive a free education but does not compare to what the NCAA is making off of them. The players should receive a cut of these profits or gain a portion of this money after graduation so it can help them financially with their futures. Sadly the NCAA is too considerate of themselves and if an athlete is injure or not performing well then they have no problem wiping their name off the record books. The National Collegiate Athletic Association is a business that makes tons of money from college athletes. Another reason why the NCAA doesn’t pay their athletes is because they will be tax and they can lose a lot of money from that. Well, professional sports obviously pay their athletes and they are tax too but the professional leagues are doing well. College basketball and college football are highly talked about and televised just like the professional sports so it shouldn’t be a problem if college athletes get paid. With amateurism in college sports, athletic programs cheat. They secretly cheat by illegally over paying top players or handing them out free stuff. For instance Cam Newton who was an All-American quarterback playing for Auburn and Mississippi before was secretly offered 120,000 to 18,000 from Mississippi State. Playing in top division one colleges, â€Å"winning isn’t everything, it’s the only thing† and if athletic programs will cheat to have the best recruits and this is no surprise. If amateurism didn’t exist, there wouldn’t be any cheating scandals and every player will treated equally from their performance.

Discussion on the 'neutrality of money' Essay Example | Topics and Well Written Essays - 2000 words

Discussion on the 'neutrality of money' - Essay Example Most schools agree on the long term neutrality of money, and the short term non-neutrality due to stickiness of wages among other factors. However, the schools differ in their theories of money and variables and policies that affect money demand and supply and other macroeconomic variables. Quantity theory of money The classical school of economists developed the quantity theory of money, which basically meant that the price level in the economy is dependent on the money supply. According to this theory inflation is caused by an increase in money supply. According to the theory that national income equals national expenditure the equation of the quantity theory is MV=PY, with V being the velocity of circulation, meaning the number of times in a year a unit of money is spent on buying goods and services, M being money supply, P being the price level and Y the national income. Classical economists through this theory asserted the neutrality of money by claiming that Y and V are exogeno us factors and unaffected by the money supply with V being constant, thus P and M are directly related and changes in money supply would only affect the prices and not output. (Sloman, 1999) Keynes (1936) rejected the quantity theory of money by asserting that a rise in money supply may not necessarily lead to a rise in the price level. This may be due to the fact that the entire increase in money supply may not be spent and may just stay in bank accounts. The Keynesians claim the velocity of circulation is inversely proportional to M and thus the V in the equation may not be a constant. An increase in money supply may lead to an increase in output if there are unemployed resources in the economy. Thus an increase in the money supply can lead to an increase in Y, provided that the economy is not at full employment and not increase prices greatly. Similarly, a decrease in money supply could lead to a decrease in output and thus income causing a decrease in Y. According to Keynes, dem and creates supply and not the other way round, which the Classical school believed. (Graham Sahaw, 1997) Milton Freidman was one of the most vociferous critics of the Keynesians, and brought back the quantity theory of money. According to him, inflation was anywhere and everywhere a monetary phenomenon based on his historical research. According to monetarists, any increase in money supply faster than an increase in output will lead to an increase in inflation. They asserted that V and Y are independent of the money supply and thus money supply will only affect prices and not income or velocity. According to the monetarists, an increase in money supply will increase prices along with employment and output in the short run, but as the economy adjusts to new prices and wages, in a couple of years output and income will adjust downward and the real effect of the increase in money supply will be inflation and vice versa with a decrease in money supply. (D.Mizen, 2000) The new classical theorists put forth the theory of rational expectations, which asserts that markets clear quickly and expectations adjust instantly to market changes. This theory assumes that people are aware of economic conditions and adjust their expectations accordingly. Thus, money is neutral in the short term as well as the long term, as expanding money supply will automatically lead to higher expectations of inflation and in turn
