Posted November 22, by Jefferson Online. The internet has become a vital part of the modern world, inseparable from daily life and routines. From simple computer networks to global interconnectivity and instantaneous wireless communications, the rapid and dramatic evolution of the internet can help with understanding the changing nature of technology and communications.

Computer viruses have been around for quite a bit and nearly all of them have been spread through the Internet or its predecessors. The first computer virus, called " Creeper system ", was an experimental self-replicating virus released in

History of the Internet

Home Computer History. Was this page useful? The term " packet " was coined by Donald Davies in , to describe data sent between computers over a network.

The first RFC surfaced in April , as a document to define and provide information about computer communications, network protocols, and procedures. NCP is a file sharing protocol for use with NetWare. Ray Tomlinson sent the first e-mail in Although it is not Wi-Fi , it helps lay the foundation for Wi-Fi. However, the first software allowing users to make VoIP calls was not available until The first routers were used at Xerox in However, these first routers were not considered true IP routers.

Ginny Strazisar developed the first true IP router , originally called a gateway , in IPv4 was the first major version of the Internet protocol.

The Internet started in the s as a way for government researchers to share information. Computers in the '60s were large and immobile and in order to make use of information stored in any one computer, one had to either travel to the site of the computer or have magnetic computer tapes sent through the conventional postal system. Another catalyst in the formation of the Internet was the heating up of the Cold War. The Soviet Union's launch of the Sputnik satellite spurred the U. Defense Department to consider ways information could still be disseminated even after a nuclear attack. In response to this, other networks were created to provide information sharing.

Here, then, is a brief history of the Internet:. The precursor to the Internet was jumpstarted in the early days of computing history, in with the U. ARPA-funded researchers developed many of the protocols used for Internet communication today.

The history of the Internet has its origin in the efforts to build and interconnect computer networks that arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France. Computer science was an emerging discipline in the late s that began to consider time-sharing between computer users, and later, the possibility of achieving this over wide area networks. Independently, Paul Baran proposed a distributed network based on data in message blocks in the early s and Donald Davies conceived of packet switching in at the National Physical Laboratory NPL and proposed building a national commercial data network in the UK.
