Designing a Simple LAN - an example

Many small businesses can use a simple LAN design to make business communications easier. For example, consider a small law office that can benefit from having a LAN. The office consists of four attorneys and one secretary. Your research about the law firm’s needs reveals that each attorney keeps information about clients strictly on his or her computer, with the exception of sharing case information when they are working with one or more of the other attorneys on a case. When working together, the lead attorney keeps information about that case on her computer and periodically prints a copy to distribute. One problem with this method is that distribution of the information is sometimes forgotten when the lead is busy on another case. When it is time to bill a client, each attorney prints a rough draft of the billable hours and hand carries it to the secretary, who compiles the information and mails the bill. The secretary also keeps the books for the law practice on her computer. Finally, your research shows that each member of the office has his or her own computer and printer. Also, when you research the potential for using a wireless connection in the building, you learn that other offices in the building have decided to use cable connections. Wireless access is intermittent because of the building materials in the walls and because of wireless interference from surrounding electrical devices.

Proposed Design

A solid design for this office using what you have learned so far consists of the following:

Design Rationale

The rationale for this design is as follows:
