Based on the criteria, the computer network can be divided into 4:
1. Based on the distribution of sources of information / data.
- This network centralized network consisting of computers and servers Client which Client computer that serves as an intermediary to access sources of information / data derived from a single server computer. - A distributed network is a combination of a centralized network so that there are some server computers are interconnected with the Client to form a specific network system.
2. Based on geographic coverage can be divided into:
- Network LAN is a network that connects 2 computers or more in coverage such as laboratories, offices, and in 1 cafe.
- MAN network is a network that includes a big city and its local area. Examples of local telephone networks, cellular telephone systems, as well as some ISP relay network Internet.
- Network WAN is a network with coverage throughout the world. PT network example. Telkom, PT. Indosat, as well as GSM networks such as Cellular Satelindo, Telkomsel, and much more.
3. Based on the roles and relationships of each computer in the data processing.
- Network Client-Server In this network there are 1 or more server computers and client computers. Computers will be computers or servers to client computers and altered through the protocol software on the network. Client computer as an intermediary to access data on a server computer and the server computer to provide information needed by the client computer.
-Network Peer-to-peer in this network there are no client computer or server computer because all computers can make sending and receiving information so that all computer functions as well as client server.
4. Based on the data transmission media
- Wired Network (Wired Network) In this network, to connect one computer to another computer in the form of necessary liaison network cable. Function in the network cable to send information in the form of electrical signals between the network computer.
- Wireless Network (Wireless Network) is a network with the medium of electromagnetic waves. In this network does not need a cable to connect between computers that use electromagnetic waves to send signals between the computer information network.
