Network Types

a. Local Area Network (LAN) / Local Area Network.

A LAN is a network that is limited by the relative area

small, generally limited by the environmental area such as a

office in a building, or a school, and usually not

distance of about one square kilometer.

Some models of LAN configuration, one computer is usually on

make a file server. Which is used to store

software (software) that govern network activity, or

as software that can be used by komputerkomputer

connected to the network. Computers

connected to the network (network) is usually called

with a workstation. Usually more below the workstation capabilities

from the file server and has other applications in hard drive

besides the application to the network. Most LANs use media

cable to connect between a computer with a computer

other.

b. Metropolitan Area Network (MAN) / Metropolitan area network

A MAN, usually covering an area larger than the LAN,

for example between regions within a province. In this network

connect multiple networks of small pieces into

larger neighborhood area, as an example, namely: Bank network

where several branches of a bank in a city

large connected between each other.

For example Bank BNI in the entire region or Ujung Pandang

Surabaya.

c. Wide Area Network (WAN) / area of Large Scale Networks

Wide area networks (WAN) is a network scope

Satellites are already using the facilities or undersea cable

as an example of the whole network BANK BNI in Indonesia

or in other countries.

Using the WAN facilities, a bank in Bandung

can contact the branch office in Hong Kong, only

within a few minutes. WAN usually rather complicated and highly

complex, use many means to connect between

LAN and WAN in Global Communications such as the Internet. But

however, between LAN, MAN and WAN is not much

differ in some respects, only just a different scope of its area

one among others.
