The correct answer is LAN.Local Area Network (LAN)Local Area Network (LAN) covers a smaller geographical area (Size is limited to a few kilometres) and is privately owned.It can be can used for an office building, home, hospital, schools, etc.LAN is easy to design and maintain.It covers a short distance, and so the error and noise are minimized.It connects network devices in such a way that personal computers and workstations can share data, tools, and programs.The group of computers and devices are connected by a switch, or stack of switches, using a private addressing scheme as defined by the TCP/IP protocol.Routers are found at the boundary of a LAN, connecting them to the larger WAN.Additional Information Wide Area Network (WAN)It is a computer network that extends over a large geographical area, although it might be confined within the bounds of a state or country. A WAN could be a connection of LAN connecting to other LANs via telephone lines.Metropolitan Area Network (MAN)It covers a larger area than that of a LAN and a smaller area as compared to WAN.It connects two or more computers that are apart but resides in the same or different cities.Its hard to design and maintain a Metropolitan Area Network.The fault tolerance of a MAN is less and also there is more congestion in the network.Personal Area Network:It is a computer network that enables communication between computer devices near a person.PANs can be wired, such as USB or FireWire, or they can be wireless, such as infrared, ZigBee, Bluetooth and ultrawideband, or UWB.The range of a PAN typically is a few meters.
