Computer Network
A network consists of
two or four computers that are connected in a series by various means (such as
printers and CD ROMS). They are connected like changing FILES or means of
electrical communication. Telephone lines, radio rays are connected through satellites
and illuminated rays etc. via cable on computer network.
There are basically
three types of networks.
1. Local Area Network (LAN).
2. Wide Area Network (WAN).
3. Metropolitan Area Network (MAN)
Local Area Network
A local area network
LAN is a network that connects small areas. It is generally limited to a
geographical area. Such as a writing lab school or building. Rarely LAN
computers have a network of more than 1 mile.
In a particular type
of LAN network, a computer is used as a file server, it stores all the software
that controls the network. A computer connected to a file server is called a
work station. These work stations are less powerful than file servers, and they
also keep additional software on their hard drives. Only used for connecting
networks on the main LAN. A computer has interfere cards. For more information
on LAN networks, the process of connecting to it is done by topology cabling
and hardware sector
Wide Area Network
Wide area networks
connect slightly larger geographic areas such as Florida and the United States
or the entire world DEDICATED TRANSOCEANIC or this type of network is used to
connect satellite uplinks. WAN uses telecommunications from Florida to Tokyo within minutes. Without paying long telephone bills. WAN is complex. They use
multiplexes to connect local and metropolitan networks like the Global
Communication Network to the Internet.
Metropolitan Area Network
A metropolitan area
network (MAN) is a network that connects users of a geographic area or a large
area larger than a local area network (LAN) but smaller than a Wide Area
Network (WAN) with computer resources.
A large computer
network spread over a city or large university campus is called the
Metropolitan Area Network or MAN. The purpose of MAN (Metropolitan Area
Network) is to provide links to the Internet over a long period of time. A MAN
(metropolitan area network) can usually consist of multiple LANs to form a
network. This large network MAN (Metropolitan Area Network) now consists of
optical fiber set-up.
