1. What are the main architectural components of a LAN? (Minimum word count: 60)
Network cards, network cables, network hubs, network switches, and routers are the main architectural components of a LAN. A network cards is the component that allows the network to talk to the computer, and the computer to talk to the other devices on the network. Network cables are the actual, physical lines that carry information between the computers, workstations, printers, and other components of the network. Network hubs are the radio stations of the network. They broadcast the data to every computer in the network, no matter where the data was intended to go. Network switches are the newer alternative to network hubs. They allow addresses to be assigned to each computer in the network, so that routing becomes easier. Finally, routers connect one network to another, whether across the building, or across the nation.
2. Describe the function and characteristics of a network operating system (NOS). (Minimum word count: 100)
Network operating systems are used to run computers that act as servers. They provide services to clients over a network. It also includes special functions for connecting computers and devices into a local area network. Network operating systems provide file and print sharing, account administration for users, security, and backing up data. Installed components must provide client functionality, as well as, server functionality. One of the key functions of the NOS is to provide network administration utilities. These allow the network administrator to perform tasks involved in managing resources and users. There is several different types of network operating systems. A variety of versions of Microsoft Server, Microsoft NT, Linux/UNIX, Mac OS X Server, and NetWare, are available, just to name a few.
