In a Network, not only computers are required but some other hardware devices are also required for the proper functioning of the network. We will be looking at specific hardware components, not cables or things already described in earlier blogs. These components have specific purposes. Let us take a look at them.
1.SWITCH:- A Network Switch is a device which connects different computers and devices on a computer network. A switch receives data, processes it, and then forwards it only to the destination device. It uses packet switching technique to transfer data on the network.

2.REPEATER:- A repeater simply copies the information arriving at its input and retransmits it from the Output. This is required at times when the network signal is weakened or distorted over a long distance. This happens if the network passes through an area having strong electromagnetic fields. The weakened or distorted signals at the input are regenerated and then retransmitted by the repeater.

3.HUBS:- A Hub is a networking device which is similar to a switch but unlike a switch which transmits the information to a particular device, a hub transmits the received information to all devices that are connected to it. That's the reason why hubs are called Dumb Switches. Hubs are comparatively cheaper than the switches.

4.ROUTER:- A router is a network device which routes the information around the network. It is also used to connect one network to other networks. The header of every packet of the information arriving at a router is checked for the destination and using the best route the message is forwarded to the next device.

5.BRIDGE:- A bridge is a device that connects amd passes packets between two network segments that use the same communication protocols. A bridge blocks off one segment of a network from another. It thus acts as a filter. The bridge checks arriving information and transmits it, only if required.
