Based on the criteria, the computer network can be divided into 4, namely:
1. Based on the distribution of sources of information / data
- Centralized network
This network consists of Client and server computers which Client computer that serves as an intermediary to access sources of information / data derived from a single server computer
- Network distributed
It is a combination of several centralized network so there is some server computers interconnected with AJAX form a certain network systems.
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.
- Network MAN
Is a network that includes a big city and the local area. Examples of local telephone networks, cellular telephone systems, as well as some ISPs 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 be able 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 perform transmission and reception of information so that all computers function as clients as well as a 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)
Network is 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.
For further explanation about computer networks will be posted on my next writing.
