ABSTRACT
Before the wide spread of internetworking (IEEE 802.1) that led to the Internet, the communication networks were limited essentially to only allow communications between the stations on the local network using a central mainframe computer. Advances led to principles of networking between physically separate networks, leading to the development of the packet switching model of digital networking in the late 1960s and 1970s, including ARPANET and the X.25 protocols. Additionally, public access and hobbyist networking systems grew in popularity, including unix-to-unix copy (UUCP) and FidoNet. –ey were, however, still disjointed separate networks, served only by limited gateways between networks. However, this led to the application of packet switching to develop a protocol for internetworking, where multiple different networks could be joined together into a super-framework of networks. By defining a simple common network system, the Internet Protocol Suite, the concept of the network could be separated from its physical implementation. –is spread of Internetworking began to form into the idea of a global
network that would be called the Internet, based on standardized protocols officially implemented in 1982.
