Ydinprosessoriyksikkö

Ydinprosessoriyksikkö, often abbreviated as CPU, is the central processing unit of a computer. It is the primary component responsible for executing instructions and performing calculations that make a computer function. The CPU contains a control unit that directs operations and an arithmetic logic unit (ALU) that performs arithmetic and logical operations. It also includes registers for temporary data storage and a clock that synchronizes operations. Modern CPUs are highly complex integrated circuits, often featuring multiple cores, each capable of processing instructions independently. This multi-core design significantly enhances a computer's ability to multitask and run demanding applications. The speed and efficiency of a CPU are measured in clock speed, typically in gigahertz (GHz), and the number of cores. Advances in CPU technology have led to smaller, faster, and more power-efficient processors, driving innovation in computing across various devices, from smartphones to supercomputers. The design and manufacturing of CPUs are core aspects of the semiconductor industry.
