NETWORKING COMPONENTS Peyusha Mohanta 8B

Networking Components A wired network connection can be defined as a configuration that involves cables which establish a connection to the Internet and other devices on the network. To establish wired networking in a group of computers, it requires some additional components that are as follows: - Network Card - Networking Cable - Modem - Hub - Switch - Router

◼ Networking Card A Network card is used to physically attach a computer to a network, so that it can participate in network communication. Ethernet Network Card is the most commonly used network card. (Nowadays, most computer motherboards have inbuilt network card.)

◼ Networking Cable Modern Ethernet networks use twisted pair cable, containing eight wires. These wires are arranged in a special order, and an RJ – 45 connector (similar in design, but bigger than the connector used with the telephone wire) is crimped at both 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 digitalThis Photo by Unknown Author is licensed 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 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 on the mother board.

◼ Hub A Hub is a network device that is used to connect all the computers 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 check 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 a hub. However, unlike a 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.

◼ Router A router is a device that connects two different types of networks with each other, for example: A This Photo by Unknown Author is licensed under CC BY- LAN with WAN. Apart from transmitting the message on the network from a source computer to the destination computer, a router also provides the best suitable route to deliver that message. It, therefore, helps to decrease the time of transmitting the message.

◼ Recapitulation ➢ A wired network connection can be defined as a configuration that involves cables which establish a connection to the Internet and other devices on the network. ➢ To establish wired networking in a group of computers, it requires some additional components that are as follows: ➢ A Network card is used to physically attach a computer to a network. ➢ An Ethernet cable, sometimes referred to as a network cable, is a cord that runs from a router, modem, or network switch to your computer, giving your device access to the local area network (LAN) — in other words, giving it internet access. ➢ The hub then transmits that request to all the other computers in the network, which check whether the message belongs to them or not. If not, then the message is dropped. This process is called broadcasting. ➢ It transmits the message from the source computer to the destination computer only by using the physical address. ➢ A router is a device that connects two different types of networks with each other, for example: A LAN with WAN.
