BENEFITS OF COMPUTERS IN VARIOUS ASPECTS OF LIFE

Definition of Computer Networks. Computer networks have a definition of a collection of computers and other devices as a supporter of computers that are connected to each other in a single unit. Media computer network without wires and can be via cable, this allows network users to exchange information, such as data or documents to print through the same printer in the same network, the user can communicate with each other (email , chat), to access the information (web browsing).Below are some of the benefits of networking.• Resource sharing, can use the resources together. For example, a user who is 100 Km away from the data, no difficulty in using such data, and it was as though the data is located nearby. This often means that the computer network address range.• High reliability, with a network of computers we will get the high reliability by having alternative sources of supply. For example, all the files can be saved or copied to two, three, or more computers connected to the network. So if one machine breaks the copy on another machine can be used.• Saves money. Small-sized computer has price / performance ratio better than a large computer. Large computers such as mainframes have speed kiro - kiro ten times the speed of a small computer / personal. But the price of mainframe thousand times more expensive than private computers. The lack seimbanggan ratio of price / performance is making the system designer to build a system that consists of a computer - Personal computer.
• As data securityThrough a computer network system, stored data will be more secure because it is stored in a central computer that can only be accessed by users who have access rights.

There are four common types of networks are used include:
- Network workgroup,
- Network LAN (Local Area Network)
- MAN (Metropolitan Area Network
- Network WAN (Wide Area Network)
