Keskprotsessoritel

Keskprotsessoritel, commonly referred to as CPUs (Central Processing Units), are the primary components of a computer responsible for executing instructions and performing calculations. They are often described as the "brain" of the computer. A CPU consists of several key parts, including the arithmetic logic unit (ALU) for performing mathematical and logical operations, and the control unit (CU) for managing and coordinating the execution of instructions.

CPUs have evolved significantly over time, with advancements in processing power, efficiency, and the number of cores. Modern CPUs are typically multi-core, meaning they contain multiple processing units on a single chip, allowing them to handle multiple tasks simultaneously. This parallel processing capability greatly enhances a computer's overall performance.

The speed of a CPU is often measured in gigahertz (GHz), indicating the number of cycles it can perform per second. Other important factors influencing CPU performance include cache memory, which stores frequently accessed data for faster retrieval, and the architecture of the processor itself.

CPUs are manufactured using complex microelectronic fabrication processes, involving intricate layers of transistors and other components. The continuous drive for more powerful and energy-efficient processors fuels ongoing research and development in the field of semiconductor technology.
