“Computer network. System or network. Is a group of computers and devices. To be connected to the network users can communicate. Exchange information. And equipment. Network interoperability, “the network is several sizes. From a small computer that connects with just a few. For use in home or in small To larger networks that connect the world of Home Network or home network. The known “LAN” (Local Area Network).

Benefits of networking.

1. Resource sharing refers to the use of devices such as printer sharing is only one printer. Anyone can use the network printer. Ease and low cost. Because many printers do not invest. (In addition to a different type of pin Times)
2. Shared files are installed when the computer system network. Using file sharing or data exchange file can quickly To any storage device. The transfer of cutting issues of capacity to storage media. Equipment except in the major hard disk storage. If the region is continuing to add full.
3. Communications The computer that is connected to a network system. Contact can talk to other computers. Based communications program that can use a computer at the same. Or make use of email within the network Home Network or Home Office to benefit the many.
4. Using the Internet together. Every computer connected to the network can access the Internet anywhere. The modem itself. Whether analog or digital current top like ADSL.

Type of Network.

1. Peer to Peer System on any computer on the network have equal base. Is all can be used in other files. And able to use a different file system as their Peer To Peer Distributed System is working with the distribution of resources to other work station, but an issue of security. Due to the confidential information will be exported to other computers as programming work is a Peer To Peer Windows for Workgroup and Personal Netware.
   
2. Client / Server Working in a Distributed Processing System, or distributed processing. It will divide the processing between the server with client Replace applications will work. Oe only on servers. Calculation of the program is split applications. Working on a client. And when the results of a client would like some information. Will be run to Servers to be only partial information is sent back. To the client to calculate it.
   
3. BUS Connected to a bus line is 1 line of computer servers. And all clients must connect the main cable line. The computer will look at the Node is a client of (Node A) want to send data to a second (Node C) will need to send data And the address of Node C to the bus cable. When a Node C will then receive information. Go to work immediately.
   
4. Ring Connect-ring A connection from one machine to another, and integrated data will export Cable ring It is passing from one To the one until the end. Problems of this architecture is If a line in the absence of any will do. Unable to send data to the Ring is used on a large family กัน IBM Token Ring network, which will be used for data transmission between a mini or mainframes with IBM’s network on the system.
   
5. Star Connect-Star Hub is a central device used in connection Where all must Hub cables, through the use of most of the packet and UTP, Fiber Optic Hub for sending data to a virtual break the signal (Repeater) Switch current is used to connect a device which higher performance and is popular today.
   
6. Wireless Lan A network using a LAN (LAN) that do not use cables to connect. That is a wireless network. Work-based radio. In transmission. This can be helpful in the matter of having to use cables. Suitable for use in the inconvenience of using cables. Without piercing the wall or ceiling to hang. It features the radio ทะลวง through a barrier wall or screen room. But it must be made in phases. If you move from computer to a remote radius is connected. Using a wireless network. Can be used with Notebook PC and need to bookmark and use the wireless LAN card installed. Including the Access Point device called a signal equipment for wireless networking. Are responsible for sending data to a wireless LAN card.
