Types of Computer Networks and His understanding

Types of Computer Networks and the His understanding - Computer network is a system or circuit that consists of two or more computers, where between one computer to another computer connected by a communication system, allowing any computer joined to the network can exchange -exchange data, programs, and other computer resources such as storage media, printers, and others.

Also through a computer network that connects computers located in remote locations, can also be established communication, such as communication via electronic mail or email, or upload the data to send and retrieve data from another place called the download. Other activities related to data communications, can also be done over the computer network.

Types of Computer Networks and His understanding

On this occasion will be published the types of computer networks and the understanding that based karaterianya can be divided into 4 parts, which are:

1. Based on the geographic range is divided into:
LAN Networkis a network that connects two computers or more in coverage such as laboratories, offices, and in one cafe.
MAN NetworksIs the tissue that covers the major cities and their local area. Examples of local telephone networks, cellular telephone systems, as well as some ISPs relay networks.
WAN NetworkIs a network with worldwide coverage. Examples PT network. Telkom, PT. Indosat, as well as Satelindo GSM Mobile, Telkomsel, and much more.
2. Based on the distribution of sources of information / data can be divided into:
Centralized networkThis network consists of client and server computer where the client computer that serves as an intermediary to access sources of information / data from one computer server
Distributed NetworkIs a combination of several centralized network so that there are multiple server computers interconnected by a network client to establish a specific system.
3. Based on data transmission media can be divided into:
Wired Network (Wired Network)In this network, to connect one computer to another computer in the form required connecting a network cable. Cable network functions to send information in the form of electrical signals between the network computer.
  Wireless Network (Wireless Network)Is a network of the medium in the form of electromagnetic waves. In this network cables are not required to connect between computers because it uses electromagnetic waves will transmit signal information between networked computers.
4. Based on the role of computers in the Process Data
Client-Server NetworkIn this network there are one or more computer servers and client computers. The computer that will be the server computer and a client computer and changed through software on the network protocol. Client computer as an intermediary to be able to access data on the server computer while the computer server providing the information required by the client computer.

Network Peer-to-peerIn this network there are no computer client or server computer for all computers can do the delivery and receipt of information so that all the computers to function as a client as well as server.
Thus articles on a variety of computer networks that have been published along with the meaning of each of these types of computer networks. Hopefully this information is probably useful.
