APARNET(Advanced Research Projects Agency Network)
ARPANET is considered the beginnings of the internet it was created by DARPA (Defense Advanced Research Project Agency) in the united states. it was developed for military purposes although it was initially a research project. the aim was to allow different bases to be able to share information. -
Newsgroups Bulletin Board
During the 1970s a system called Unesent developed by, utilising the current network technology allowed users to post messages to newsgroups which could be read by all registered members of the newsgroup. From then on Unesent developed bulletin boards that grew as the size of the internet netwroks grew. -
Email
After developing a method of connection to computers across a great distance the next step the took was to find a way to communicate to each other. APARNET sent the very first message at 10:30 p.m on 29 of october 1969 the concept was developed by ray tomilison who then instigrated the @ sign. -
International Packet-Switched service
The first packet-switched network,like APARNET, was created in 1978. It was a collaberation between Western Uninon (a US communications company) and the post office in the UK. they were succesful and the IPSS network grew within Europe and United States and spread to Australia, Hong Kong and Canada -
Increasing number of hosts
In 1984,the number of host on the internet reached 1,000.Three years later, in 1987 it exceeded to 10,000 and one year later they figured out how to raise the host to 60,000. Then in 1989 it had reached 100,000, it would only be another three years before they figured out how to topple 100,000 and reach 1 million and now the figure to this day is 500 milion and still counting. -
TCP/IP protocol, National Science Foundation (NSF)
All parts of APARNET and connected networks were officially converted using TCP/IP protocol, meaning that every part of the internet could see the same method of communication. After that the National Science Foundation created their own network similar to APARNET for purpose of education snd research called NSFnet. which then merged together with NSF, the result was a stronger backbone, meaning this is a super network could continue growing -
Domain & Adressing
Origanlly,users of ARPNET would conatact other members of the network using telephone numbers.they would dail indiviuals computer and that would be the network they could acess. With growth they were finally able to figure out how to use domain names that were unique which used human language rather than the computer lagnuage. URL's started with www and end in an extension such as .com or .co.uk -
Search Engines
the first search engine was created in 1990 by an american university student called archie, its aim was to achive and be able to search for information over the internet at its highest point it reprtedly held 150 gigabytes of indexting data which came to a huge amount. compare this with google, which can process around 20,000 terabytes. -
First commercial dail-up
although modems were connected to telephone lines they had been used from time to time to intercept internets, it was only late 1990s that dail-up modems had became available to the public with an online speed of 9600 bps, compared to the 56 kbps which came standard in 1998. the current speed available through broadband are anything up to 1mbps upwards to 50mbps and even faster. -
World Wide Web
the first real webpage was published on the internet in 1991. prior to this Tim Berners-Lee and Robert Cailliau, working with CERN, created the feature that allowed this to happen:hypertect and hyperlinks. Tim Berners-Lee is often credited with being the inventor of the WWW (World Wide Web)
