CPU Architecture refers to the design and organization of a computer's central processing unit, which is the component responsible for executing instructions and processing data. It includes the layout of the CPU's internal components, such as the arithmetic logic unit (ALU), control unit, and registers, as well as how these components interact with each other and with other parts of the computer. Different types of CPU Architecture, such as x86 and ARM, have distinct features and capabilities. These architectures determine how efficiently a CPU can perform tasks, manage power consumption, and support various software applications. Understanding CPU architecture is essential for optimizing performance in computers and other devices.
