A network consists of two or more computers that are linked in order to share resources (such as printers and CD-ROMs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. The three basic types of networks include: Local Area Network (LAN) Wide Area Network (WAN) Local Area Network A Local Area Network (LAN) is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart.

		LAN ^Votes:0 Local Area Network The Local Area Network (LAN) is by far the most common type of data network. As the name suggests, a LAN serves a local area (typically the area of a floor of a building, but in some cases spanning a distance of several kilometers). Typical installations are in industrial plants, office buildings, college or university campuses, or similar locations. In these locations, it is feasible for the owning Organisation to install high quality, high-speed communication links interconnecting nodes. Typical data transmission speeds are one to 100 megabits per second. A wide variety of LANs have been built and installed, but a few types have more recently become dominant.

In effect it's whatever you want or need it to be, but basically it's where two or more computers have the ability to communicate with each other. Maybe the simplest type of computer network is one where two PC's are linked together via a single piece of cable. Using Windows 98, for example, it is possible to 'link' or network two PC's together using DCC (Direct Cable Connection) software via the serial (usually used for connecting an external modem) or parallel (usually used for connecting a printer) ports.

		What's a Network ^Votes:0 What's a Network A computer network is nothing more than two or more computers connected together in order to share information. It's a simple but very powerful concept. Networked computers (also called nodes, clients, workstations, and servers) perform three key functions; they share files, resources (printers, disks, etc.), and programs. Each node has its own unique hardware address to identify it on the network. A networked computer that provides resources is called a server. The computer accessing those resources is called a workstation, a node or client. Servers are usually the most powerful computers on the network because other computers share their resources. Workstations are usually PCs, which are cheaper and less powerful. A computer may be a server or a workstation but rarely bo Read More Go to Site
