A microprocessor, often referred to as a central processing unit (CPU) or simply a processor, is a multipurpose, clock-driven integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides an output. Microprocessors are the brains of computers and many other electronic devices. They perform the arithmetic, logic, and control operations that are essential for a device's functioning.

The key components of a microprocessor include the arithmetic logic unit (ALU), which performs calculations and logical operations, the control unit (CU), which directs the flow of operations and interprets instructions, and registers, which are small, fast memory locations used to hold data and instructions temporarily. Microprocessors are designed to execute a set of instructions, known as an instruction set, which defines the operations the processor can perform.

The development of the microprocessor has been a driving force behind the digital revolution. Early microprocessors were relatively simple and had limited processing power. However, over time, advancements in semiconductor technology have led to increasingly complex and powerful microprocessors. This progress is often described by Moore's Law, which observes that the number of transistors on a microchip doubles approximately every two years, leading to exponential increases in performance and reductions in cost.

Microprocessors are ubiquitous today, found in everything from personal computers and smartphones to automobiles, home appliances, and industrial control systems. Their ability to process information rapidly and efficiently has enabled the development of sophisticated software and advanced functionalities across a vast array of applications.
