Answer to Question 1
If the firm anticipates growing in the future, it may want to consider planned growth. Purchase decisions should be made with that growth in mind. In the future, the firm will certainly have more than one attorney and one paralegal. A network purchased now should be expandable to include new employees in the future.
Answer to Question 2
A computer system includes at least one input device, a computer processor, and at least one output device. A computer system in a law office could be a single stand-alone personal computer, but is more likely to be a number of personal computers linked together by a network. The network file server would permit everyone in the office to have access to the same software and files. In a large law firm, a mainframe system might still be used.
