History
Computers have been used to coordinate information in multiple locations since the 1950s, with the U.S. military's sage system the first large-scale example of such a system, which led to a number of special-purpose commercial systems like Sabre.In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology. This effort was funded by ARPA (now DARPA), and the COMPUTER network that it produced was called the ARPANET The technologies that made the Arpanet possible spread and evolved. In time, the network spread beyond academic and military institutions and became known as the net.
Nature
Some computers may divide their work between one or more separate CPUs, creating a multiprocessing configuration. Traditionally, this technique was utilized only in large and powerful computers such as supercomputers, mainframe computers and servers. However, multiprocessor and multi-core (multiple CPUs on a single integrated circuit) personal and laptop computers have become widely available and are beginning to see increased usage in lower-end markets as a result.
Definition
A computer is a machine which manipulates data according to a list of instructions which makes it an ideal example of a data processing system.
