A central processing unit (CPU) on a single chip. A modern microprocessor can have several million transistors in an integrated-circuit package that can easily fit into the palm of one’s hand. Microprocessors are at the heart of all personal computers. When memory and power are added to a microprocessor, all the pieces, excluding peripherals, required for a computer are present. The most popular lines of microprocessors today are the 680x0 family from Motorola, which powers the Apple Macintosh line, and the 80x86 family from Intel, which is at the core of all IBM PC–compatible computers.

An integrated circuit semiconductor chip that performs the bulk of the processing and controls the parts of a system.
Complete computer central processing unit contained on a single integrated circuit, or chip. The appearance of the first microprocessor 1971 designed by Intel for a pocket calculator manufacturer heralded the introduction of the microcomputer. The microprocessor has led to a dramatic fall in the size and cost of computers, and dedicated computers can now be found in washing machines, automobiles, and so on. Examples of microprocessors are the Intel 8086 family and the Motorola 68000 family. + prikaži više
