Types of Computer Networks - LAN WAN MAN
and Area Networks by Austin Whitten
A computer network is the practice of linking two or more computing
devices together for the purpose of sharing data. Networks are built with
a mix of computer hardware and computer software. This interconnected
system will share services and interact through a communications link.
A computer network is very helpful in a business. Most of the time a
business will have more than one computer set up and it often very
beneficial to network all of the computers in the office. A local area
network (LAN) will connect your company's computers. This will allow them
to share and exchange different types of information. If you haven't
considered networking your office computers, listen to these reasons.
There are several types of computer networks. A computer network can be
very simple, such as only connecting two computers or a computer and a
printer, or it can be very complex, connecting millions of computers and
devices. Here is a list of different computer network types.
The smallest type of network is a Personal Area Network (PAN). This type
of computer network connects a computer to a number of devices. These
devices may include, but are not limited to, printers, PDAs, and
telephones. Usually these are located very close to a computer. A Local
Area Network (LAN) is used to network a small geographical area. An
example of this type of computer network is a home network with two or
more computers or computers that are connected in a workplace. A version
of a LAN is a Wireless Local Area Network (WLAN).
A Campus Area Network (CAN) is ideal for a university but they are also
found in industrial facilities. This type of computer network connects
computers in a number of buildings. This is generally accomplished through
bridging and routing. A Metropolitan Area Network (MAN) consists of any
number of interconnected LANs and WANs but it will not extend certain
boundaries, such as those of a town, city, or metropolitan area. Many of
these are operated at public utilities and are used by businesses and
individuals in the area.
A Wide Area Network (WAN) is a step up from a MAN. This type of computer
network can cross metropolitan or even national boundaries. The best known
WAN is the Internet. This computer network uses routers and public
communication links to carry data. Many WANs are run by private companies
and restricted, unlike the Internet. Although these are the MAN types of
network that most users come across there are other computer networks
ranging from as small as a Desktop Area Network (DAN) to a very large
Global Area Network (GAN).
