Computer Network computer(nc), also named thin client, is a terminal unit that works under the network environment. Comparing with the pc, it has no hard disk, floppy disk and cd-rom. It gains the resources from the network. The software and data are stored on the server. Nc has convenient data interface and data processing ability close to the pc. Therefore, besides characteristics shared with pc, nc is easier in management. It widely used in the area of government, army, bank, taxation, enterprise, school and habitation. The advantages of nc: The cost of installation reduces by 30%. The total cost in five years reduces by 80%. The electric charge reduces by 92%. The cost of software reduces more.
