What You Should Know about Computer Networks
Computer network science is a popular science that even some of university offer Msc Computer Networks on their graduate School. Computer network itself is the practise of linking two or more computing devices together for the purpose of sharing information. Networks are built with a mix of computer hardware and computer application. This interconnected method 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 let them share and exchange different types of information. In case you haven’t thought about 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 with a printer, but it can be very complex as well, connecting few millions of computers and devices. Let’s take a look at the different computer network types.
The smallest type of network is a Personal Area Network (PAN). This type of computer network connects a computer to numerous devices. These devices may include, but are not limited to, printers, PDAs, and rings. Usually these can be found 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 six 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 present in industrial facilities. This type of computer network connects computers in numerous buildings. This is usually accomplished through bridging and routing.
A Metropolitan Area Network (MAN) build from any number of interconnected LANs and WANs but it won’t extend the definite boundaries, such as those of a town, city, or metropolitan area. Lots of 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 Net. This computer network makes use of routers and public communication links to over information. Lots of WANs are operated by private companies and usually restricted, unlike the Net. Although these are the MAN types of network that most users come across there’s other computer networks ranging from as small as a Desktop Area Network (DAN) to a very giant Global Area Network (GAN).
Hope this article will give you a general understanding of computer networks.
