Connection Types


Many different types of computer networks exist in the world, and many of these require different types of connections.

Personal Area Networks


Personal area networks (PANs) are very small networks that are used for the comunication between several computer devices in a small area. This can include devices such as

Local Area Networks


Communications network that serves users within a confined geographical area. It is made up of servers, workstations, a network
operating system and a communications link. LANs usually involve a server on which which stores all the data on the network. If the network is quite small in size, then it may allow each computer in the network to be a server, but when the networks become larger a dedicated server is often needed to handle increased amount of data being processed. Multiple dedicated servers are often used in larger networks. The LAN is controlled by the network operating system. The data is transferred through the ethernet cablesd or other type of cable through the network adaptor of each computer. This allows all computer on the network to access the information, if they have security clearance, as if it was stored on their own computer.

Wireless

Wireless Local Area Networks (WLANs) are a variety of LAN that use wireless signals to connect through wireless routers that allow the computers to comunicate with each other. This wireless is used either instead of, or in conjunction with the ethernet cables that provide connectivity in wired LANs.

Wide Area Network

Wide Area Networks (WANs) are a series of LANs that are networked together
