          Definition of Computer Networks. Computer networks have the definition of a set of computers and other devices as supporting 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 share information, such as data or documents, can print through the same printer in the same network, the user can communicate between each other (email , chat), to accessing information (web browsing).

          In a computer network there are two parties interacting with each other to achieve the common goal of the client and server pihat. Client side is the party receiving or requesting service, while the server is the party who send or deliver the service. In addition there is a computer in a network of tens, thousands, and even millions of nodes. Node is any computer or other device connected to a network.

Benefits of Computer Network

1. As sharing resources
          Which aims to ensure that all equipment, programs, and other peripherals can be used by any user on the computer network.

2. As the development and maintenance of equipment
          With the development of computer network equipment will be much easier and can save costs at the same time, for every purchase of components such as printer then simply buy one fruit alone, so that the printer can be used together. Besides computer network also allows users (user) in treating hard drive and other devices, such as providing protection from virus attacks, hard enough to focus on the central computer only.

3. As an effective communication medium
          Computer networks can make the communication among users to one another, both for sending information or messages that are important and for teleconferences.

4. As data security
          Through 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.

5. As data integration
          With the computer network, the reliance on a central computer can be reduced, because each data processing is not all done by one computer, but can be processed on another computer. Therefore computer network can establish data integration that allows users to process and obtain information at any time.

Thus the discussion of the meaning of computer networks and their benefits may add insight you all :)
