Detailed explanation-1: -Central Processing Unit (CPU) The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it.
Detailed explanation-2: -The actual mathematical operation for each instruction is performed by a combinational logic circuit within the CPU’s processor known as the arithmetic–logic unit or ALU. In general, a CPU executes an instruction by fetching it from memory, using its ALU to perform an operation, and then storing the result to memory.
Detailed explanation-3: -Random access memory (RAM) Its function is to store programs and data so that they are ready for use when the CPU needs them.
