Basic computer network

Basic computer network
Based on the criteria for a computer network consists of four parts :

1. Based on the distribution of information or data sources
Network-centered
This network consists of server and client computers where the client computer only serves as an intermediary to access the source data or information derived from one server computer
- Distributed Network
This combination of multiple networks, so there are few centralized network server computers that are interconnected with the client to form a specific network system

2. Based on geographic coverage
- Network LAN (local area network)
Is a network that connects two or more computers in a small scope like a lab, cafe, offices, etc.

- Network MAN (metropolitan area network)
A network in a city with high-speed data transfer, which connects various locations such as campuses, offices and so forth. MAN network is a combination of several LANs. Coverage of this MAN among 10 to 50 km, MAN this is the right network to build a network between the offices in one town between the plant and agencies and headquarters located within range
- Network WAN (wide area network)
Is a computer network covering a large area as an example of a computer network among regions, cities or even countries, or can be defined as well as computer networks require routers and public communications channels.
WAN is used to connect a local network with other local networks, so users or computers in one location can communicate with users and computers in other locations.
- Network Internet (international networking)
This network covers the whole world

3. Based on the roles and relationships of each computer in the process data.

- Client-Server Networks
In this network there are one or more server computers and client computers. Computers that will be a server computer or client computer must be altered through software on the network protocol. As an intermediary for the client computer can access data on a server computer and the server computer provides the information required by the client computer.

- Networking Peer-to-peer
In this network there are no client computer or server computer because all computers can do the delivery and reception of information so that all computers function as clients as well as a server.

4. Based on data transmission media

- Wired Network (Wired Network)
In this network, to connect one computer to another computer network cables required. Function in the network cable to send information in the form of electrical signals between the network computer.

- Wireless Network (Wireless Network)
Network is a form of electromagnetic waves with the medium. On this network is not necessary cables to connect between computers because it uses electromagnetic waves to transmit signals between the computer information network.
