Computer Science - Operating Systems Concepts - Discussion

How is that possible and what is the reason behind this?

What is the explanation? please post it.

You can see that in the given options only operation code is capable of conducting some operation that too at machine level.

I hope you are satisfied with my answer.

What is the explaination post it.

Operation code only says about the operations performed in micro processor.

Operation code is right answer.

An instruction includes an opcode specifying the operation to be performed, such as "add contents of memory to register", and zero or more operand specifiers, such as registers, memory address or physical data.

Operation code is the better answer.

Operations code are used in assembly language to instruct the MP that which instruction is going to excute.

Detailed explanation:.

CPU has ALU (arithmatic and logic unit) for performing many arithmatic and logical operations and CU (control unit) for sending control signal to tell ALU about which operation to be performed.

As we have many operation to be performed by the same hardware unit of ALU, so we should have different binary equivalent code to identify each operation and that binary code is called opcode.

Control unit decode the opcode and issue corresponding control signal to perform appropriate operation between operands.
