four university computers. In 1972 the ARPANET had its first public demonstration at the International Computer Communication Conference. In the same year, Ray Tomlinson designed the first application for this new network: e-mail. The ARPANET had used a protocol called NCP, but it had compatibility problems. Engineers needed to design protocols that could meet the needs of an open-architecture network. Roberts and Cerf then led the team that created the Transmission Control Protocol/Internet Protocol (TCP/IP), which swiftly became the standard Internet protocol. In 1983 the ARPANET switched from using NCP to TCP/IP, and the network was separated into military (MILNET) and non-military systems. By 1985 the Internet was well established among scientific researchers and developers, and was beginning to be used for daily computer communications. By the early 1990s, access had
