What Is a Central Processing Unit (CPU)?
A Central Processing Unit (CPU) is the main component of a computer system. It acts as the brain of the computer, performing calculations and controlling all other components in order to execute instructions given by software programs. The CPU consists of two parts: an arithmetic logic unit (ALU), which performs mathematical operations such as addition, subtraction, multiplication and division; and a control unit (CU), which manages data flow between memory and input/output devices. CPUs are typically made up of multiple cores that can process multiple tasks simultaneously for improved performance.
The speed at which a CPU operates is measured in hertz or gigahertz (GHz). Modern CPUs have speeds ranging from 1 GHz to 5 GHz or higher depending on their type and model number. Additionally, modern CPUs also come with integrated graphics processing units (GPUs) that allow them to handle more complex graphical tasks than traditional GPUs could manage alone. This allows users to enjoy better gaming experiences without having to purchase additional hardware components like dedicated video cards.
