A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Unlike a typical personal computer, an SBC may not include slots into which accessory cards ("daughterboards") may be plugged. An SBC may be based on almost any available microprocessor, and may be built up from discrete logic or programmable logic. Simple designs, such as built by computer hobbyists, often use static RAM and low-cost eight or 16 bit processors.

Famous quotes containing the word computer:
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
