notebook A computer about the size of a piece of A4 paper (about 20 by 30 cm) and a few cm thick with a hinge along the long side. When opened up, a full-sized keyboard and monochrome or color LCD screen are revealed. Notebooks can have all the processing power and features of desktop computers. To increase their flexibility the pointing device is often a trackerball embedded in the keyboard rather than a mouse, which requires a hard flat surface to operate successfully. See also subnotebook, laptop computer, palmtop computer.
