keskprotsessorüksust
The term "keskprotsessorüksus" is the Estonian word for Central Processing Unit, commonly known as the CPU. The CPU is the primary component of a computer that performs most of the processing. It acts as the brain of the computer, executing instructions from software and hardware. This involves arithmetic, logic, control, and input/output (I/O) operations specified by the instructions. The CPU is typically housed on a single integrated circuit (IC) chip, often referred to as a microprocessor. Its speed is measured in Hertz (Hz), with modern CPUs operating at gigahertz (GHz) frequencies. Key characteristics of a CPU include its clock speed, the number of cores, and its cache memory. These factors significantly influence a computer's overall performance. The CPU fetches instructions from memory, decodes them to understand what needs to be done, executes the required operations, and then writes the results back to memory. This continuous cycle is fundamental to the operation of any digital computer.
