The concept of computer network born in the 1940s in America of a development project in the laboratory computer MODEL I Bell and Harvard University research group led by professor H. Aiken. At first the project was to utilize a computer device that must be used together. To do some of the process without much waste of time was made vacant succession process (batch processing), so some programs can run on a computer with the rules of the queue.
Ditahun 1950s when the types of computers began to swell up to the creation of a super computer, a computer must serve several terminals (see Figure 1) For that discovered the concept of distribution of time-based process known as TSS (Time Sharing System), for the first time form network (network) computer application. In the TSS system several terminals connected in series to a host computer. In the process of TSS began to seem a mix of computer technology and telecommunication technology that was originally developed on their own.
Entering the 1970s, after much work load increased and the price of computers began to seem very expensive, then start to use the concept of the distribution process (Distributed Processing). As in Figure 2, in this process some of the host computer to do a great job in parallel to serve several terminals are connected in series in each host computer. Dala distribution process is absolutely necessary in-depth blend of computer and telecommunications technology, because in addition to the process that must be distributed, all must serve the host computer terminals in a single command from the central computer.

Computer networks distributed processing model
Furthermore, when the small computer prices have started to decline and the concept of the distribution process has matured, then the use of computers and networks have started a variety of start dealing with the process and communication between computers (Peer to Peer System) alone without going through a central computer. For that began developing the local network technology known as the LAN. Similarly, when the Internet was introduced, the majority of stand-alone LAN began an association and forming a giant network WAN.
