The CPU (Central Processing Unit) is the primary component of a computer that performs most of the processing inside a system. It executes instructions from programs, performs calculations, and manages data flow between other hardware components like memory and storage.
Often called the “brain” of the computer, the CPU interprets and processes instructions from software applications, operating systems, and user inputs. Its performance is determined by factors such as clock speed, the number of cores, and cache memory.
CPUs are used in computers, smartphones, servers, and embedded devices, enabling all digital operations. Modern CPUs can handle multiple tasks simultaneously, making them essential for multitasking, gaming, data processing, and artificial intelligence applications.
