Introduction Basics of Computer Network

Based on the criteria, the computer network that is differentiated into 4:

1. Based on the distribution of sources of information / data

- Centralized Network
This network consists of computer and server klient which klient computer that serves as a mediator for access to sources of information / data derived from a single computer server

- Network are
Is a mix of some of the network, so there is some centralized computer server that relate to each other klient establish a specific network system.


2. Based on the geographic range is distinguished:

- Network LAN
is a network that connects 2 or more computers in coverage, such as laboratory, office, and in 1 cafe.

- Network MAN
Is a network that covers a large city and its local area. For example the network of local phone, cellular phone systems, network and Internet relay some ISPs.

- WAN Network
Is a network with coverage across the world. For example the network of PT. Telkom, PT. Indosat, and GSM networks such as Cellular Satelindo, Telkomsel, and many more.


3. Based on the role and relationship of each computer in the processing of data.

- Client-Server Network
In this network, there are 1 or more computer servers and client computers. Computers that will become a computer server and the client computer and changed through the software on the network protokolnya. As the client computer to access data on a server computer while the computer server to provide the information required by the client computer.

Network-Peer-to-peer
In this network there is no client computer and server computer because the computer can do all the delivery and reception of information so that all the computer work as well as client server.


4. Based on the data transmission media

- Network Berkabel (wired Network)
In this network, to connect one computer to another computer needed a cable network operator. Cable network functioning in sending information in the form of electrical signals between a computer network.

- Wireless Network (Wireless Network)
Is a network with a medium electromagnetic waves. In this network is not required to connect a cable between the computer because it uses electromagnetic waves that will send the signal information between the computer network.


For further explanation on the computer network will be posted on writing my next.
