what is a network? once you have got two or more computers to link up to one network, which means they are able to share one printer, this is good so that because it means you can buy one expensive printer which links up to more than one computer instead of one printer per computer

LAN (local are network) Once the computers are connected together into a LAN, this means many people can share and use the same resources at the same time. They can share files, software, hard disks and peripherals such as a printer or CD-ROM. this means they are linked between networks this is good because you can be in the building next door and still link up.
