Types of Networks explained by Al-Huda the largest hub for networking courses in Multan.
Ø Depending upon the physical part covered by a link, it is
classified as:
- · Local Area Network (LAN)
- · Metropolitan Area Network (MAN)
- · Wide Area Network (WAN)
- · Personal Area Network (PAN)
Local Area Network (LAN)
v
A LAN is a network that is
used for connecting between computer devices, commonly within an office
structure or home.
v LAN’s allow the sharing of incomes such as files or hardware devices that may be desired by multiple users.
v LAN’s allow the sharing of incomes such as files or hardware devices that may be desired by multiple users.
v
Is limited in size, usually
covering a few hundred meters, and no more than a mile.
v
Is fast, with speeds from
10 Mbps to 10 Gbps.
v
Involves little electric
wiring, usually a single cable between to each device.
v
Has lower cost related to
Men or WAN’s.

v Each LAN uses a protocol – a set of rules that governs how packets are organized and communicated.
v LAN’s can be either wired or wireless. Twisted pair, coax or fiber optic cable can be used in wired LAN’s.
v Nodes in a LAN are connected together with a definite topology. These topologies contain:
·
Bus
·
Ring
·
Star
v
LANs are capable of very
high transmission rates (100s Mb/s to G b/s).

Metropolitan Area Network (MAN)
v A metropolitan area network (MAN) is a large computer network
that commonly spans a city or a large campus.
v A MAN typically covers an area of between 5 and 50 km diameter.
v A MAN is improved for a larger geographical area than a LAN,
alternating from some blocks of buildings to entire cities.
v Examples of MAN: Telephone company link that provides a high-speed DSL to clients and cable TV network.

Wide Area Network (WAN)
v A WAN is two or more LANs related together. The LANs can be many
considerably apart.
v
The world's most general
WAN is the Internet.
v Multiple LANs can be associated together using devices such as
bridges, routers, or gateways, which allow them to share data.
v WAN covers a large geographic area such as country, the continent or
even the whole of the world.

Personal Area Network (PAN)
v A PAN is a link that is used for communicating between computers
and computer devices (including telephones) in close by the proximity of about a
few meters within a room.
v PAN’s can be located wired or wireless
v A personal area network (PAN) is a computer network used for
communication surrounded by computer devices, containing telephones and
personal digital assistants, in proximity to an individual's body.
