Computer Networking

Computer networking was invented to connect computers to communicate with each other. Communication between computers is faster and easier than any other form of communication. In addition to faster communication access, unauthorized computer networks computer users on remote programs and databases. In addition to these strengths, there are some other advantages of computer networks. Computer networking reduces the cost of business processes through the hardware and software resources available to access and downsizing to micro-networks rather than mainframes. The data collected from several sources has to process easily, which also ensures the reliability of the information provided.

Definition of computer network

A computer network is as a coherent system in which each computer connected to the communication, which would allow resources and information available from any node to be accessed.

When most people think, they think of the computer networks of large companies. Many people have their systems in home network to enable shared Internet connection, shared files, and printing functions are also shared. The process of sharing resources and data between multiple computers is a computer network called. If you connect computers together, they can not only share the Internet connection, printer, fax and other components, but also in a position, files, photos, songs and other data to share on your hard disk.

Networking Explained

The network in a local network or a small LAN where computers within an office building or room used at home can be divided, the people are two or more locations over a connected region and WAN, which created the network to home or can be connected in the office from anywhere in the country.

WAN is the most common use for the connectivity that allows the network to connect to millions of computers around the globe. The WAN is the largest network in the world and through the connection, if a router and running the appropriate software, you can be connected to any location around the world.

Computer networks are classified by nature. They LAN, WAN, MAN and PAN networks. These are the relatively small LAN, consisting of several hundred computers, in the same building and are directly linked. A LAN that is not bringing with them a wireless LAN cable. Large networks, a large geographical area, such as cities or two countries are involved in a WAN.

WANs were initially very expensive. However, most of these networks in use today use the Internet, which is universal and publicly, not to be so controlled by the user and to be very beneficial from a financial point of view. Last but not least, the networks PAN Personal Area Networks, which are the smallest networks on an area of ??several meters at most. Such a network includes several computers that are connected and that a person is carrying. You have a cell phone, for example, the MP3 player or a portable navigation system.
