Key Components of a Network
Key Components of a Network — By: Alex Panagis
Hub — A device connecting multiple Ethernet devices together and making them act as a single network segment.
Switch — A device used on a computer network to actually connect devices together. Multiple cables and connections can be made to a switch to allow computers on a single network to work together.
Router — A router is a device that connects 2 or more networks. Routers are a fundamental key to the internet and other complex networks.
Repeater — A repeater is a device that receives a transmission and forwards them (re-transmits) at a higher level of power. This is used so that signals can move over a large distance and over various obstacles.
Bridge — A device that separates a network segment within one logical network. A bridge is usually places between two different computers that talk to each other, but not as much as in the same group. From an ideological point of view, it is a metaphorical bridge for data to be moved between to two different groups of computers.
Network Cards — A network card is a piece of hardware that is used to connect a computer to a computer network (usually LAN).
Wireless Access Points — A wireless access point is a device that allows wireless devices to connect to a wired network using WiFi.
Modem — A modem is a device or program that enables a computer to transmit data through different means of transportation, like a telephone or cable line.
Computer information is stored digitally, whereas information transmitted through telephone lines is in the form of analog waves. The modem is the device that converts between those two forms — Analog and Digital.
Network Cable — A networking cable is a piece of hardware separated from the computer that is used to connect one network device to other network devices, or to connect two or more computers to share a printer, scanner etc.
