The Most Influential Audio-Visual Technological Discovery

In order for something to be the most influential discovery ever it must follow certain criteria. I'm defining the word discovery to be synomous with invention in that it is something that was "happened upon" and developed and didn't necessarily exist for all time. In order to be the most influential it must permeate every part of our lives, from leisure, education, business, and travel, to the very social system itself. It must be capable of world wide use and also improve life both orally and visually for all members of society.

The most important audio-visual discovery of the 20th century is by far the internet. It has revolutionised almost every aspect of our lives from the way we study, work, shop, relax and above all communicate.

The internet as we know it developed from a government project to send secure information from one remote computer to another. The DARPA (Defence Advanced Research Projects Agency) began work on the internet in 1973 under the guiding influence of Larry Roberts. He designed the Arpas first network where a machine called an Interface message processor (IMP) would connect individual sites, route messages, scan errors and confirm the arrival of messages at their intended destination. A number of innovations led to the development of the modern internet. First was the development of the computerised bulletin board (today's message boards) by Ward Christensen and Randy Seuss, second was the standardisation of internet access through TCP (transfer Control Protocol) and IP internet protocol, and third was the development of software for information retrieval which would become the WWW. World wide web. (Moschovitis et al)

The internet consists of a global network of computers joined together to form one large interconnected network. It relies on Routers, Naps, ISPs, DNS and powerful servers to connect the network.

Each computer on the network uses a modem to connect to the ISP (Internet service Provider eg Eircom) which operates the telephone lines. When you connect to the internet you become part of their network. Companies may be part of a Local Area Network all connected at points of presence in various cities. There is no overall connecting network but several high level networks connected to each other through Network Access Points or NAP's. Backbones, or fibre optic trunk lines, carry the information through routers, or specialised computers which sort and determine where to send your information.

    Computers were in development from as early as the 1950’s, but the general public wouldn’t hear of the World Wide Web until the 1980’s. By the year 2000, the internet was accessible to the general public from their home computers. It was used mainly for e-mailing, online shopping and research, but with its growing popularity, the World Wide Web was quick to expand its content. We can now, in the present day, access the internet on a number of platforms such as mobile phones, laptops and PCs, and even Smart Televisions, which makes a vast difference to the platforms people used 30 years ago.

    The internet was created to test new networking technologies developed to eventually aid the military. The Arpanet, advanced research projects agency network, became operational in 1968 after it was conceived by Leanard Roberts (Watrall, T101, 2/2). Ever since the Arpanet began in 1968, it grew exponentially in the number of connected users. Traffic and host population became too big for the network to maintain, due to the killer application known as email created in 1972. The outcry for a better way sparked the development of the NSFNet. The National Science Foundation Network replaced Arpanet, and ultimately had many positive effects. This early division of the internet spread its netw...

    The internet is a global system of interconnected computer networks that use the internet protocol suite to link several billon devices worldwide (Wikipedia). The internet is sometimes simply referred to as the ‘Net’ or the “online world”, is now the most ubiquitous or universal conveyor of electronic information (Gourley). The term internet essentially refers to the broadcasting, transfer, and reconstruction of digitally-coded data between two or more machines equipped with computer chips. For the today’s online users, the flow of bits and bytes occurs instantly and invisibly. Yet, The internet was technically born decades ago, but the internet was introduced to the world when a company, named Netscape, went public in 1995. Netscape introduced the masses to the free flow of electronic information through a web browser. In other words, it is the translation of digital data from remote repositories and the results are displayed on screen (in form of a website or web page) – while well known online companies like America Online and CompuServe existed prior that time, both restricted their users to from their own portfolio of proprietary data, which is a closed end system known as the Intranet.

    Working with Internet does not mean just browsing www and sending and receiving e-mails. The Basic Structure of the Internet was developed through last 30 years of existence of the Internet. The Internet is a heterogeneous worldwide network consisting of a large number of host computers and local area networks. The Internet uses the TCP/IP suite of protocols. This allows the integration of a large number of different computers into one single network with highly efficient communication between them. This way, the user can access information on all kinds of host computers from a desktop PC, Macintosh, or whatever he/she has available. TCP/IP, the communication standard underlying the Internet, originates from work done at the US-Department of Defense in the late 1960s. The first version of the Internet was built in 1969 and consisted of just four computers. In 1982 a set of specifications and protocols have been implemented, which became known as TCP/IP in reference to their two major elements, the "Transmission Control Protocol" and the "Internet Protocol". The development and implementation of TCP/IP stimulated a massive growth process for the Internet. "By late 1987 it was estimated that the growth had reached 15% per month and remained high for the following two years. By 1990, the connected Internet included over 3,000 active networks, over 3,000 active networks, and over 200,000 computers. By January 1992 the number of hosts on the Internet was 727,000, doubling about every 7 months. Various groups of users are connected to the Internet: universities and other educational institutions, government agencies, the military, and at an increasing number private businesses.

  • History And Development Of The Internet

    982 Words  | 2 Pages

    The Internet started as a Defense Department Cold War experiment in the 1950’s. (Academic American, 225). The government needed a way to relay information between tanks and headquarters so the APRA (Advanced Research Projects Agency) sought a way to let signals from the battlefield reach a headquarters computer using satellites and radio signals. At the same time the command posts of the nation were located deep underground in mountains in fear of nuclear war. (Diamond, 3). Paul Baran, working for the U.S. Air Force, developed a network that could reroute itself around damage caused by the impact of an Intercontinental Ballistic Missile by using "redundancy of connectivity". This meant that in the event of a break in the network the server would re-route the information in an alternate path through a new technique called "packet switching". Packet Switching is a means of breaking up the message being sent into small packets which carry enough information to seek out its destination and sending them out separately towards the destination server. The message after being broken up would take separate routes to the destination and then be re-assembled by the computer at the server where the message was being sent. This was good because with more than one route for information to travel on, the enemy did not have one central point to target their attack to break the lines of communication and in the event of some break in the line information could still travel through. (Diamond, 4).
