A network can be as simple as attaching two or three computers together to form a workgroup. Then, they can easily share data files and a printer.
More complex systems involve multiple file servers across the country or around the world.
Equipment Selection Assistance - provided for selecting file servers, hubs, routers, and LAN interface cards. File servers - Networks can be set up using either Windows95, Microsoft Windows NT, or Novell NetWare. Workstations - Each workstation attached to the LAN can be configured with appropriate software so it can communicate with the rest of the network. This would include client software for e-mail systems or for accessing the Internet. Workstation environments covered are DOS, Windows 3.1, Windows for Workgroups, Windows95 and 98, Windows NT and NetWare.
