Fundamentals Of Computer Networking

In the past, if two people want to share data between them

, they were loaded mobile media such as diskettes and CD-ROM. These possibilities of data transfer between remote computers are often difficult, especially when files are transferred frequently. Given the problems mentioned in the transfer of data in offshore platforms, the idea of linking two or more computers comes. Instead of transferring the files to the movement of the plates are the computers connected by pipeline connections to the computer.

If someone transferring data to another computer, you can share transfer files across the network. Thus, a portable hard drive is needed and the case is simple. When talking about computer networks, we must distinguish between the many types that distinguish the network. The computer network, depending on the geographic area in which they are or how they behave when the order to share and access data between computers on the network.

Let us first see how they are classified by geographic area. The purpose of this classification is how the network or simply supplement what is the size of the network. There are three types for all networks under this classification. Is the LAN, WAN and MAN. LAN (Local Area Network) is the smallest size in comparison with other species. The LAN is a living room, one floor of a building as a society, or more than one group of adjacent buildings. MAN (Metropolitan Area Network gaming) is an entire city or even country for some time. Moreover, the WAN to an entire country or group of countries or even worldwide. The second classification is based on the distribution of data across the network and how computers connected to each other, are treated. There are two types of networks in this ranking. The first is the peer-to-peer.

The purpose of this classification is that all computers on the network are treated as equals. Therefore, the amount of data on a computer the same size, and the other on a computer. The computing power and storage of all devices are equal. There are no computers on the network with a value greater than the other team. Hence the name, peer-to-peer. The second type of networks according to the above classification, client-server network. Thus, the case is different, because all the teams in the same amount. At least there is one computer (the server) is powerful and the power of memory. Therefore, the data stored on your computer are shared on the network. Every team that some information may be shared on the network, or by the server. This is because all PC and server memory sizes less CPU power too.
