This document discusses computer networks and local area networks (LANs). It defines a network as consisting of two or more linked computers that share resources and exchange files. The computers can be connected by cables, phone lines, wireless technologies or other means. A LAN is described as a group of computers and devices connected by a common line or wireless link and sharing resources within a small physical area, ranging from a few users to thousands. Common network components, topologies, and standard network types are also outlined.

- 6. 6 Topology Advantages Disadvantage S BUS Takes less cable Break in the Bus, network is down Ring Easy to install Expensive parts Star Easy to install; most common; break in workstation cable, network still works More expensive than Bus
- 7. Topologies Description Linear Bus All nodes and peripheral devices are attached to a common backbone cable. Ring All nodes are connected in a circular chain. Star All nodes are connected to a central hub.
- 9. A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link. Typically, connected devices share the resources of a single processor or server within a small geographic area . . A local area network may serve as few as two or three users or as many as thousands of users. 9
