Local Area Network (LAN)
Main article: Local Area Network (http://en.wikipedia.org/wiki/Local_Area_Network)
A network covering a small geographic area, like a home, office, or building. Current LANs are most likely to be based on Ethernet technology. For example, a library will have a LAN for users to connect to the internet. All of the computers in the library are connected through a system of hubs and eventually connect to the internet. The hub is just like what it sounds. A bicycle wheel uses a hub and spokes - all the spokes connect to a central point - the hub.
LANs use different technologies to link computers together. Depending on the circumstance, the computers in the network might be connected using cables and hubs. Other networks might be connected strictly wirelessly. It depends on the number of PCs that you are trying to connect, the physical layout of your workspace, and the various needs that you have as you develop your network.
The defining characteristics of LANs, in contrast to WANs (wide area networks), include their much higher data transfer rates, smaller geographic range, and lack of a need for leased telecommunication lines. Current Ethernet or other IEEE 802.3 (http://en.wikipedia.org/wiki/IEEE_802.3) LAN technologies operate at speeds up to 10 Gbit/s. This is the data transfer rate. IEEE (http://en.wikipedia.org/wiki/IEEE) has projects investigating the standardization of 100 Gbit/s, and possibly 40 Gbit/s. Inverse multiplexing (http://en.wikipedia.org/w/index.php?title=Inverse_multiplex&action=edit) is commonly used to build a faster aggregate from slower physical streams, such as bringing 4 Gbit/s aggregate stream into a computer or network element with four 1 Gbit/s interfaces.
