Four Types of Networks
MAN
A MAN is optimized for a larger geographical area than a LAN, ranging from a several blacks of buildings to entire cities.
MAN
A MAN might be owned and operated by a single organization, but it usually will be used by many individuals and organizations.
MAN
A MAN often reacts as a high speed network to allow sharing of regional resources.
MAN
A MAN typically covers an area of between 5 and 50 km diameter.
WAN
A WAN is two or more LANs connected together. The LANs can be many miles apart.
Metropolitan Area Network (MAN)
A large computer network that usually spans a city or a large campus.
Personal Are Network (PAN)
A network that is used for communicating among computers and computer devices in close proximity of around a few meters within a room
PAN
A personal area network is a computer network used for communication among computer devices, including telephones and personal digital assistants, in proximity to an individual's body.
Wide Area Network (WAN)
Covers a large geographical area such as country, continent or even whole of the world.
LAN
Every LAN uses a protocol - a set of rules that governs how packets are configured and transmitted.
MAN
Examples of MAN: telephone company network that provides a high speed DSL to costumers and cable TV network.
LAN
Has lower cost compared to MAN's or WAN's
LAN
Is fast, with speeds from 10 Mbps to 10 Gbps
Lan
Is limited in size, typically spanning a few hundred meters, and no more than a mile
PAN
It can be used for communicating between the devices themselves, or for connecting to a larger network such as internet.
LAN
LAN's can be either wired or wireless. Twisted pair, coax or fibre optic cable can be used in wired LAN's
LAN
LAN's enable the sharing of resources such as files or hardware devices that may be needed by multiple users
WAN
Multiple LANs can be connected together using devices such as bridges, routers, or gateways, which enable them to share data.
LAN
Nodes in a LAN are linked together with a certain topology
PAN
PAN's can be wired or wireless
LAN
Requires little wiring, typically a single cable connecting to each device
PAN
The devices may or may not belong to the person in question. The reach of a PAN is typically a few meters.
WAN
The world's most popular WAN is Internet.
WAN
To cover great distances, WANs may transmit data over leased hgih-speed phone lines or wireless links such as satellites.
Local Area Network (LAN)
a network that is used for communicating among computer devices, usually within an office building or home.
Network
a network that is used for communicating among computer devices, usually between an office building or home.
Disadvantages
• Expensive To Install • Requires Administrative Time • File Server May Fail • Cables May Break
LAN
• LANs are capable of very high transmission rates (100s Mb/s to G b/s).
Advantages
• Speed • Cost • Security • E-mail • Resource Sharing
