Question

I need to know the diferences between PAN, LAN, CAN, MAN and WAN.

Answer 1

LAN

The most basic and common type of network, a LAN, or local area network, is a network connecting a group of devices in a “local” area, usually within the same building. These connections are generally powered through the use of Ethernet cables, which have length limitations, as the speed of the connection will degrade beyond a certain length.

A WLAN, or wireless LAN, is a subtype of LAN. It uses WiFi to make the LAN wireless through the use of a wireless router.

HAN

A HAN, or home area network, is a network connecting devices within a home. These networks are a type of LAN. All the devices inside the household, including computers, smartphones, game consoles, televisions, and home assistants that are connected to the router are a part of the HAN.

CAN

A CAN, or campus area network, usually comprises several LANs. They cover a campus, connecting several buildings to the main firewall. A university could use a CAN, as could a corporate headquarters.

MAN

Even larger than a CAN, a MAN is a metropolitan area network. These can cover an area as large as a city, linking multiple LANs through a wired backhaul. An example of a MAN would be a citywide WiFi network.

WAN

In contrast to the smaller LAN and HANs, a WAN is a wide area network, covering any distance necessary. The Internet could be considered a WAN that covers the entire Earth.

Answer 2

A personal area network (PAN) is formed when two or more computers or cell phones interconnect to one another wirelessly over a short range, typically less than about 30feet.

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.

A campus network, campus area network, corporate area network or CAN is a computer network made up of an interconnection of local area networks (LANs) within a limited geographical area.

A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan area.

A wide area network (also known as WAN), is a large network of information that is not tied to a single location. WANs can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.
