Computer means a device that performs logical operations and processes data. Computers are composed of, at a minimum:
(1) A central processing unit (CPU) to perform operations;
(2) User input devices such as a keyboard, mouse, digitizer, or game controller; and
(3) A computer display screen to output information. Computers include both stationary and portable units, including desktop computers, integrated desktop computers, notebook computers, thin clients, and workstations. Although computers must be capable of using input devices and computer displays, as noted in (2) and (3) above, computer systems do not need to include these devices on shipment to meet this definition. This definition does not include server computers, gaming consoles, mobile telephones, portable hand-held calculators, portable digital assistants (PDAs), MP3 players, or any other mobile computing device with displays less than 4 inches, measured diagonally.
