Document Summary

Objective 1: discuss the importance of computer networks. Computer network: two or more computers that share resources. Peer-to-peer network (p2p): each computer is considered equal & can share resources with every other device. The computer that is sharing a resource must be turned on & accessible by other computers in the network. Router: a device that connects two or more networks together--game console & internet- connected tv. Homegroup: (windows) consists of the computers on you home network running windows 7--or a later version of windows--that are configured with the same homegroup information. Members of a homegroup automatically share their picture, music, & video libraries and printers with each other without additional configuration. To share resources with macs, linux, or older windows computers, you must use a workgroup. Client-server network: a network that has at least one server at its center which provides a way to centralize the network management, resources, & security.
