About Computer Network Subject

The merging of computers and communications has had a profound influence. On the way computer systems are organized. The concept of the ‘computer center’ as a room with a large computer to which users bring their work for processing is now totally obsolete. 

The old model of a single computer serving all of the organization’s computational needs has been replaced by one in which a large no. of separated but interconnected computers do the job. These system are called computer network.

Objectives behind the study of this subjects are
  • To develop an understanding of computer architecture and its performance.
  • To Introduce students about different types of network and network topology.
  • To Introduce about different networking protocols and their working.
  • To expose students to emerging technologies and their potential impact.
Pre-Requisites:  Student should  have knowledge of Computer Fundamental, Hardware, Basic of  networking devices.
