Processors
The processor is the heart, the intelligent central element, of a computer or other digital information handling system. It is the part that does all of the processing, the actual work of performing arithmetic or logic operations. Everything else in current computers mostly only holds information, as bits.
Some technical names for processors: Central Processing Unit (CPU), Arithmetic Logic Unit (ALU). Processors can be of many pieces or can be one piece (monolithic). Older processors were always in many pieces, current ones are usually monolithic. Processors that fit fully on one integrated circuit chip are often called microprocessors, and have parts (features) measured in microns or micrometers (millionths of a meter). The future will bring nanoprocessors, with parts measured in nanometers (billionths of a meter), and made with a technology called nanotechnology.
