  • Roots of Computer Networks

    Computer Networks as a Result of the Computing and Communication Technologies Evolution The computer networks covered on my site are obviously not the only type of networks created throughout human civilization. Possibly the oldest example of a network covering large territories and serving multiple clients is the water supply system of ancient Rome. But no matter how remote and distinct by nature different networks can seem, they all have something in common. For example, it is possible to draw a clear analogy between the components of electric networks and those of any large scale computer networks. That is, the information resources found in computer networks correspond to Power Stations; communication links of computer networks are analogous to high voltage transmission lines, and access networks are similar to transforming stations.  Finally, both in computer networks and electric networks, one can find client terminal—End-user workstations in computer network and household electric appliances in electric network. Computer networks are also known as datacom or data transmission networks, represent a logical result of the evolution of two of the most important scientific and technical branches of modern civilization—Computing and Telecommunication technologies. On one hand, computer networks represent a particular case of distributed computer systems in which a group of computers operate in a coordinated manner to perform a set of interrelated tasks by exchanging data in an automated mode. Computer networks can also be considered a means for transmitting information over long distances. To do so, computer networks implement various methods of data encoding and multiplexing that are widely adopted in telecommunication systems. Batch-Processing System First consider the origins of computer networks. The computers of 1950s – large, bulky and expensive – were intended for a small number of privileged users. Quite often, these monstrous constructions occupied entire buildings. Such computers were not able
