Portable Computer
this generic term refers to any small, self-contained computer systems. Unlike pocket computers, which only allow the user to access data on a large mainframe, portables allow the user to gain control of the mainframe. They are expensive, and are redundant if you own a droid, but they don't get tempermental and don't require regular memory wipes. Portable computers have two primary components: the power supply and onboard memory. A flip-up display provides access to the keyboard.
