Networking Components-converted

Networking Components To establish wired networking in a group of computers, you require some additional components that are as follows: Network Card A network card is used to physically attach in a computer, so that it can participate is network communication. Ethernet Network Card is the most commonly used network card. Nowadays, most motherboard of computer have an inbuilt network Networking Cable Modern Ethernet networks use twisted pair cable, containing eight wires. These wires are arranged in a special order, and a RJ-42 connector [similar in design, but bigger than the connector used with the telephone wire] is crimped at both the ends of the cable.

Modem A modem enables you to connect your computer 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 lines. At the destination, the receiving modem further converts the analog signal into digital signals to that the data can be understood at the receiving end. It comes as a separate part that can be installed on the Peripheral Component Interconnector (PCI) slot found on the mother board. Hub A hub is a network device that is used to connect all the computer in a network with each other. When a computer sends a request in a network, it is first sent to the hub by the cable. The hub then transmits that request to all the other computers in the network, which checks whether the message belongs to them or not. If not, then the message is dropped. This process is called broadcasting.

Switch A switch works similar to hub. However, unlike hub, the switch does not broadcast the message on the entire network. It transmits the message from the source computer to the destination computer only by using the physical address. This way, the switch provides a direct connection between the source and destination. As a result the speed of the network increases.
