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:
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
