Network Cables
Network cables are used to connect computers. The most commonly used cable is Category 5 cable RJ-45.

Network Cables
A computer can be connected to another one via a serial port but if we need to connect many computers to produce a network, this serial connection will not work.

Network Distributors
The solution is to use a central body to which other computers, printers, scanners, etc. can be connected and then this body will manage or distribute network traffic.

Router
A router is a type of device which acts as the central point among computers and other devices that are a part of the network. It is equipped with holes called ports. Computers and other devices are connected to a router using network cables. Now-a-days router comes in wireless modes using which computers can be connected without any physical cable.
