Detailed explanation-1: -The processor is the brain of a computer. It is also called the central processing unit (CPU). It interprets and executes instructions of computer programs or the operating system.
Detailed explanation-2: -Control Unit: The control unit is the section of the CPU that selects interprets and sees to the execution of program instructions. It controls the input as well as the output. ALU: The full form of ALU is Arithmetic Logic Unit.
Detailed explanation-3: -An instruction set (used in what is called ISA, or Instruction Set Architecture) is code that the computer processor (CPU) can understand. The language is 1s and 0s, or machine language. It contains instructions or tasks that control the movement of bits and bytes within the processor.
Detailed explanation-4: -A CPU “receives” instructions from memory, by asking for them by address. The only commands a CPU “sends” (in the simplistic view, at least) are commands to the memory to deliver data, and commands on I/O buses, to operate I/O devices.
