The Central Processing Unit (CPU) is considered the brain of the computer because it performs all the essential calculations, processes instructions, and manages data flow within the system. It is responsible for executing commands given by software programs, making logical decisions, and controlling other hardware components. The CPU consists of three main parts: Arithmetic Logic Unit (ALU): This part handles mathematical calculations and logical operations, such as addition, subtraction, and comparisons. Control Unit (CU): It directs the operation of the processor by fetching, decoding, and executing instructions. It also manages communication between the CPU and other components. Registers: These are small memory storage units inside the CPU that hold data and instructions temporarily for quick processing. The speed and efficiency of a computer largely depend on the CPU’s performance, measured in GHz (gigahertz) , which determines how many instructions it can...
