Network

Computer network is an autonomous group of computers that are interconnected with each other using a communication protocol via a communication medium that can share information, program - a program, use of common hardware such as printers, hard drives, and so forth. In addition a computer network can be defined as a collection of a number of communication terminals located in various locations that consist of more than one interconnected computers.
The benefits of building a computer network, namely:
A. Sharing resources
Sharing resources intended for the entire program, or other peripheral devices can be utilized by any person who is on a computer network without being influenced by the location and the influence of the user.
2. Media Communications
Computer network allows for communication between users, both for the teleconference and to send messages or other important information.
3. Data Integration
Computer networks can prevent dependence on a central computer, because every process data should not be done on one computer only, but can be distributed to other places. Therefore the data is then integrated to form that allows users to obtain and process information at any time.
4. Development and Maintenance
Development of equipment can be done easily and cost-saving, because every purchase of components such as printers, the printer does not need to purchase a number of existing computers but just one fruit because the printer can be used together - the same. Computer networks also facilitate the user in taking care of the hard drive and other equipment, such as to provide protection against virus attacks then the user simply focus on the existing hard drive in the computer center.
5. Data Security
Computer Network Systems can provide protection against data. Because the administration and setting permissions to the users, and technical protection of the drive so that the data get effective protection.
6. Resource Efficient and Current Information
With shared use of resources - the same, 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 directly known by every user.
