Definition of Computer Networks

Computer Networks : Understanding Computer Networks

Understanding of computer network is a collection of computers and other devices supporting computers connected together in a unity. Media computer network can be via wires or wirelessly enabling network users are able to exchange information, such as documents and data, can also do the printing on the same printer and together using the hardware and software are connected to the network. Each computer, or devices that are connected in a network is called a node. In a computer network can have two, tens, thousands or even millions of nodes.

Computer Network is a group of autonomous computers interconnected with each other using a communication protocol through the medium of communication so that they can share information, programs - programs, use of shared hardware such as printers, hard drives, and so on. Besides computer network can be defined as a collection of a number of communication terminals located in various locations consisting of more than one interconnected computers.

Benefits gained in building computer networks, namely:

    Sharing resources

Sharing resources intended for the entire program, equipment or other peripherals can be utilized by any person who is on a computer network without being influenced by the location and the influence of the user.

    Media Communication

Computer networks allow communication between users, both for the teleconference and to send a message or other important information.

    Data Integration

Computer networks can avoid reliance on a central computer, because every process data should not be done on one computer only, but can be distributed to other places. Therefore, it is then able to form an integrated data that allows users to acquire and process information at any time.

    Development and Maintenance

The development tools are simple and cost-saving, because every purchase components such as printers, so no need to buy a computer printer there but just one piece because the printer can be used together - together. The computer network also allows users to take care of the hard drive and other equipment, for example, to provide protection against virus attacks the wearer enough to focus on the hard drive on a computer center.

    Data Security

Computer Network Systems can provide protection against data. Since the granting and setting permissions to users, as well as technical protection against hard drive so that the data get effective protection.

    More Resource Efficient and Current Information

With the use of shared resources - together, will get the maximum results and high quality. In addition the data or information accessed is always new, because any changes that occur can be readily immediately known by every user.
