Besides computer networks can be understood as a collection of communications terminals at different locations over a computer comprising interconnected.
Computer networks typically use a protocol for communication over the network, a widely used protocol is TCP / IP, IPX / SPX or NetBUI.
The benefits of computer networks:
- Resource sharing.
By sharing resources, all programs, equipment or other peripherals can be used by a person connected to the computer without being limited by the location.
- Media Communications
Computer-network communications between users, both the conference and send a message or other important information. - Data Integration
Computer networks may prevent dependence on the central computer, as each process data should not be run on a computer can only be spread to other places. Therefore, this is the formation of an integrated data that enables users to obtain and process data at any time.
- Development and Maintenance
Development of the equipment can be done simply and cost savings, for every purchases of parts, such as printers, the printer does not need a number of existing computers to buy, but only for a printer that can be used together. The computer user in the care of the hard disk and other devices, for example to protect against virus attacks available to users just concentrate on the hard disk in the computer center.
- Data Security
Computer Network Systems can provide protection to the data. Because the award and set permissions for users and technical protection against hard disk so that data to get effective protection.
- Efficient use of resources and timely information
With the use of resources together, get maximum results and high quality. Besides the data or information accessed is always the last, because every change that occurs can be directly known by each user.
