Define LAN and WAN

 . Local Area Network (LAN)  A LAN is a network that is used for communicating among computer devices, usually within an office building or home.   LAN’s enable the sharing of resources such as files or hardware devices that may be needed by multiple users • • Is limited in size, typically spanning a few hundred meters, and no more than a mile.  Is fast, with speeds from 10 Mbps to 10 Gbps.  Requires little wiring, typically a single cable connecting to each device.  Has lower cost compared to MAN’s or WAN’s.  LAN’s can be either wired or wireless. Twisted pair, coax or fiber optic cable can be used in wired LAN’s. Advantages of LAN :    The data is transferred at an extremely faster rate in local Area Network.  Local area network (LAN) provides higher security. Disadvantages of LAN :   Initial cost of installing local area network is quite high.  Unauthorized user can access critical data of an organization in case LAN ad...
