Chapter 7:
In this chapter, the concept e-mail has be explored and executed in the ARPANET. Initially, the ARPANET was designed for resource sharing, but scientists still explored the possibility of sending messages through ARPANET. The first electronic-mail delivery was sent in 1972 using a protocol CPYNET hack by the scientist Tomlinson. However by expanding it, created major compilations which forced scientist to create a standardized protocol for sending and receiving email. In 1977, a proposed format for ARPA Network was created. Then with a functional e-mail program, interestingly, sparked a debate on what should be said on the ARPA net. There a few scientists that started flame wars through the ARPANET causing controversy in the MSGroup and ironically made MSGroup the first virtual community.
Chapter 8:
In this chapter, the scientists were discussing the medium over which was traveled. Bob Taylor and Norm Abramson thought if it may be possible to transmit data packets over a wireless. The first prototype of this implementation is ALOHANET which was constructed at the University of Hawaii. This also lead to the possiblety of having a smaller portable computer sites which was devised by Roberts and Kahn. The result was disappointing due to the slow speed of the packing switching, but it still intrigued many scientists. Another radical idea was to create network between the server networks (ARPANET, PRNET and SATNET) together. It would lead to creation of the TCP protocol and thus the Internet. ARPANET disconnected in the late 80’s. As it became obsolete, it spawned even more networks, e-mail innovation and the creation of Ethernet.
