Differentiate between the following: LAN, MAN, WAN, and PAN.

Question

What will be an ideal response?

Answer 1

Alocal area network (LAN) is a network that connects computers and devices in a limited geographical area, such as a home, school, office building, or closely positioned group of buildings. Each computer or device on the network, called a node, often shares resources, such as printers, large hard drives, and programs. Often, the nodes are connected via cables.?Ametropolitan area network (MAN) is a high-speed network that connects local area networks in a metropolitan area, such as a city or town, and handles the bulk of communications activity across that region. A MAN typically includes one or more LANs but covers a smaller geographic area than a WAN. A MAN usually is managed by a consortium of users or by a single network provider that sells the service to the users. Local and state governments, for example, regulate some MANs. Phone companies, cable television providers, and other organizations provide users with connections to the MAN.?Awide area network (WAN) is a network that covers a large geographic area (such as a city, country, or the world) using a variety of wired and wireless transmission media. A WAN can be one large network or can consist of multiple LANs connected together. The Internet is the world's largest WAN.?Apersonal area network (PAN) is a network that connects computers and devices in an individual's workspace using wired and wireless technology. Devices include smartphones, digital cameras, printers, and more. A PAN may connect devices through a router using network cables or directly using special USB cables. PANs also may use Bluetooth or Wi-Fi technology. A body area network (BAN), sometimes called a body sensor network (BSN), is a type of PAN that wirelessly connects sensors worn by, carried by, implanted in, or attached to a human body.
