First of all, thank you to both Steve Wozniak and Steve Jobs for creating Apple! Thanks.
The second part of the reading mostly dealt with how computers were not only being used by the army but by people in their homes. The birth of social networking began with the creation of Internet and Ethernet. During the Cold War, there was a need for a system that could exchange information between military computers. Advanced Research Projects Agency or ARPAnet, is a division in the military that created top secret systems and weapon during the Cold War. Charles M. Herzfeld, a former director of ARPAnet believed that the system of data exchange should not only occur within the military but for the people at home. In order for the sharing of information to work, a computer breaks its information into IP or Internet Protocol packets, which are kind of like digital envelops. Then, TCP or Transmission Control Protocol makes sure the packets are delivered from person to server. So, from ARPAnet the first electronic mail (e-mail) was created in order to send simple messages to another person across the network. Soon, the Internet Protocol software was being placed on every type of computer and this caused the birth of using in-house networks also known as Local Area Networks (LAN's). Keep in mind that Internet only connects remotely located computers by telephone lines. Ethernet, which is totally different from Internet is a system for connecting computers in a building using hardware running from computer to computer. Robert Metcalfe of Xerox promoted and created Ethernet using newly designed chips and wiring. The use of personal computers became very popular thanks to Metcalfe and the revolution of using the Ethernet to connect people became the most widely installed LAN protocol.
