Computer Networks Tutorials

I listed different computer networks tutorials as per gate cse syllabus for computer networks subject is here in this post.

These computer networks notes are explained in form of different tutorials.

Link of computer networks tutorial for different topic is given here.

I hope these computer networks tutorials will assist to cover gate cse syllabus for computer networks and preparation.

Computer Network Course Description

In computer networks or data communications and networking we connect different computers and Communications Devices to make a computer networks this had a large influence.

On the way computer systems are organized. The concept of the ‘computer center’ as a server room with a large computer and devices to which users bring their work for processing is now become 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The old model of a single computer serving all of the organization’s computational needs has been replaced by one in which a large no.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 in data communications and networking.

These system are called computer networks.

Computer Networks Course Objectives

Objective of behind the development of these computer networks tutorials is to provide the knowledge of computer networks subject to computer science graduates.

Some objectives are as follows:

To develop an understanding of networking devices, OSI and TCP/IP Model
To Introduce students about different types of networks and Network Topology.
To Introduce about different networking protocols and their working.
To make aware students with emerging technologies and their impact.
Candidate or students will be able to solve GATE (CS/IT) and UGC NET questions.

Pre- Requisite

Student should have knowledge of Computer Fundamental, Hardware, Basic of networking devices.
