Definition of Computer Network

A computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked

computing devices pass data to each other along with data connections.

History : In the late 1950s, early networks of communicating computers included the military radar system Semi-Automatic Ground Environment (SAGE).

Networking Peripherals

• Router

A router is a device that forwards data packets between networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks

• Firewall

In computing, a firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on a rule set. A firewall establishes a barrier between a trusted, secure internal network and another network (e.g., the Internet) that is not assumed to be secure and trusted.

• Switch

A network switch or switching hub is a computer networking device that links network segments or network devices
