Describe a LAN
A. The diagram below illustrates the computer connections in three areas of a large company.
First look at the description of the office area network. Then write similar descriptions of the other two areas.
• In the office area, the computers are connected in a Token Ring network. Various PCs have access to a file server, an IBM mainframe, an e-mail server, and a printer.
The file server probably contains application programs like databases, spreadsheets and accounting packages. The mainframe contains large amounts of information about the company, administrative work, etc.
B. If you use a network write a short description of it, with details of its architecture and protocol. Say what you and your colleagues use the network for.
