| Introduction to computer network |
Communication, whether it is between humans, animals or computers, involves the transfer of information. In the past few decades, communication technology has increased a lot. Computers are becoming smaller and more powerful. The merger of computer and communication technology has a profound effect on how to organize computer systems. The old model of a single powerful computer serving all the computing needs of an organization has been replaced by a large number of small and autonomous computers interacting with each other. These systems are called computer networks.
