Detailed explanation-1: -A computer program is a list of instructions that can be executed by a central processing unit (CPU). A program’s execution is done in order for the CPU that is executing it to solve a problem and thus accomplish a result.
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.
