Computer network is a collection of two or more interconnected computers to perform data communication. Relationship between two or more computers that can occur through wired or wireless medium (without cable). The data can be communicated in the form of text, sounds, images, or video.
History of computer network started in 1940 in the United States through the development of a computer project at Bell Labs Model I and Harvard University research group led by Howard Aiken. At that time, the project aims to utilize only a computer device that can be used together. In 1950, when computers began to grow and supercomputers born, there was the need for a computer that can serve many terminal. Then was found the concept of TSS (Time Sharing System) or the queuing system. In 1969, formed the first computer network called ARPANET.
Benefit or advantage built computer networks are:
a. computers that are connected to make sharing files and folder sharing, ie the use of file or directory together
b. with a centralized file storage (file server), files or data on the server can be shared
c. allows the use of applications jointly by multiuser
d. allows us to backup data (backup data)
e. allows us to get the latest data / current rapidly.
There are two ways to classify types of computer networks, namely:
a. computer network based wide area or region
b. computer network based on the topology (shape) network
c. computer network based transmission media.
