1970s History of Computers
Robert Kahn exhibits the first public demonstration of the ARPANET at the International Computer Communication Conference. This public demonstration is also the first time that electronic mail (email) is exhibited and is a major catalyst for increasing interest in developing network technology. The first email programs called SNDMSG and READMAIL are written by Ray Tomlinson marking the beginning of one of the most widely used applications today.

ARPANET adopted TCP/IP on January 1, 1983, and eventually morphed into what is considered as the modern Internet.
The term Wi-Fi becomes part of the computing language and users begin connecting to the Internet without wires. It went from DSL dial up to broadband. It first came to the light as the FCC passed it by allowing it to happen. Then an industry standard change happened. Vendors soon came to the conclusion that a common wireless standard made sense too. Vendors also had to agree by committee on the acceptable standards and guidelines for the WiFi product. Once agreed, it allowed for a data-transfer rate of two megabits per second, using either of two spread-spectrum technologies, frequency hopping or direct-sequence transmission.The new standard was published in 1997, and engineers immediately began working on prototype equipment to comply with it. Two variants, called 802.11b (which operates in the 2.4GHz band) and 802.11a (which operates in the 5.8GHz band), were ratified in December 1999 and January 2000 respectively. 802.11b was developed primarily by Richard van Nee of Lucent and Mark Webster of Intersil.
