First appearing as massive machines seen only in areas of high technology, the computer eventually found its way into offices in the smaller, more accessible form of the personal computer (PC). As computers and software have become easier to use, or more “user friendly,” many people are finding them both useful and necessary for their jobs. A typical personal computer has components to display and print information (monitor and laser printer); input commands and data (keyboard and mouse); retrieve and store information (CD-ROM and disk drives); and communicate with other computers (modem).
