Networking Components by Aarav Singh Sisodiya

Networking Components - By Aarav Singh Sisodiya To create a wired networking in a group of computers, we require some additional components and these components are called networking components. The components are as follows: 1. Network Card • It is used to physically attach a computer to a network. • The most commonly used network card is Ethernet Network Card. • Nowadays, most computers have inbuilt network card.

2. Networking Cable • Modern Ethernet use twisted pair cable, containing eight wires. • The wires are arranged in a special order. • An RJ-45 connector ( a connector bigger than the connector used with the telephone wire) is crimped at both the ends of the cable. 3. Modem • It helps us to connect our computers to the available internet connection over the existing telephone lines. • It converts the digital signals of a computer into analog signals

to enable their transmission via phone. • The receiving modem further converts the analog signals into digital signals. • So that the data can be understood at the receiving end. • It comes as a separate part that can be installed on the Peripheral Component Interconnect (PCI) slots. • These slots are also found on the mother board. 4. Hub • It is a network used to connect all the computers in a network with each other.

• The messages, requests, etc. sent in a network are first sent to the hub by the cables. • Then, it transmits the messages, requests, etc. to all the other computers in the network, which check whether the message belongs to them or not. • If not, the message is dropped. • This is called broadcasting. 5. Switch • It works similar to a hub. • However, unlike a hub, switch does not the message on the entire network. • It transmits the message from the source computer to the

destination computer only by using the physical address. • A switch provides a direct connection between the source and destination. • As a result, the speed of the network increases. 6. Router • It is device that connects two different types of network with each other. • It also provides the best suitable route to deliver the messages that are transmitted from a source to the destination computer.

• Therefore, it helps to decrease the time of transmitting the message.
