to computers. This was a mix of data transmission technology and a teletypewriter. The result was an interactive terminal. These terminals were connected to a server with low-speed lines, allowing the users to interact with the computer and take advantage of its resources. Time-sharing gave multiple users the ability to use the computer at the same time, for completely separate tasks, and provided them with interactive feedback about what their programs were doing. Demand for the services of these large computers increased which meant upgrades had to be made frequently to keep the processing power ahead of the user need. These systems, called Mainframes, had been designed to provide computing power, but did not have the flexibility to satisfy the growing set of applications.
             Also, in the 1960's the military used networks to communicate to one another. It worked like the time-sharing network. They needed this network to communicate between cities, bases, and states. There was also a concern about a nuclear war. If there was a nuclear war how would people communicate? There needed to be a network that would be able to work after a nuclear strike. They came up with a "hot potato network." Basically the information would be tossed like a hot potato from user to user until it reached its destination. The actual route it took was not important. This meant that if big parts of the network were destroyed the message would try another route. As you can probable see this was not as efficient compared to the traditional telephone system.
             During the 1970's and 1980's, networking was continuously being upgraded. Businesses, schools, and the government needed faster networking capabilities to handle all the people that were using the basic "time-sharing" network. In 1975, the first personal computer was marketed in kit form. This computer was called the Altair. The Altair features 256 bytes of memory. Bill Gates, with others, wrote...
