FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A local area network (LAN) is a group of computers and peripheral devices that share a common communications line or wireless link to a server within a distinct geographic area. A local area network may serve as few as two or three users in a home office or thousands of users in a corporation’s central office.

Detailed explanation-2: -A local area network (LAN) is a collection of devices connected together in one physical location, such as a building, office, or home. A LAN can be small or large, ranging from a home network with one user to an enterprise network with thousands of users and devices in an office or school.

Detailed explanation-3: -What is a Small Area Network? Like the familiar Local Area Network (LAN) used to connect computers within an office or building, a Small Area Network (SAN) is used to connect Integrated Circuit (IC) components on a printed circuit board, or within a box or system.

Detailed explanation-4: -A personal area network (PAN) is the smallest and simplest type of network. PANs connect devices within the range of an individual and are no larger than about 10 meters (m). Because PANs operate in such limited areas of space, most are wireless and provide short-range connectivity with infrared technology.

Detailed explanation-5: -LANs are used mainly for resource sharing. Expensive hardware like laser printers and CD/ROM drives can be shared by several users when they are attached to a network. Further, purchasing a network version of software cuts the costs of purchasing them for each and every computer.
