Local Area Network (LAN) Hardware Key Terms
Make the right network connections with LAN hardware terminologySetting up a LAN, or local area network, is fairly easy. There will be some challenges in choosing types of security protocols, finding good installation areas and dealing with software requirements. On the hardware side, though, it's basically a matter of selecting quality pieces from the list below. Take a look at the basic key terms for the gear you need, and make sure all of them are compatible for the best chance at designing a functioning commercial LAN environment for a business.
RouterIn a LAN, the router is the "distributor" of the signal. A wired router disperses the signal through cable. A wireless router sends it over the air. The router generally includes WEP (Wired Equivalent Privacy) or WPA (Wifi Protected Access) encryption and security protocols, which are important for protecting business data shared over the network.
Network interface cardA network interface card, or NIC, is a piece of hardware that connects a computer to a LAN network. If a computer has an internal card, no installation is required. If not, buyers can purchase a plug-in network card to connect a computer to a LAN.
USBUSB (universal serial bus) is a type of connectivity that offers multiple possibilities for getting computers connected to networks. Businesses can find wireless cards with USB connectivity to make getting connected a simple matter of plugging in.
LAN hubThe LAN hub is a component that connects all of the computers to the router. LAN hubs are available in various styles and promote connectivity in different ways.
Cat5 cableAlong with all of the above devices, there is one more important LAN hardware component, cable. The cabling used for LAN connections must meet certain qualification for carrying data at speed. Cat5 cable is the current standard for LAN options.
