Computer Science - Operating Systems Concepts - Discussion

Address is right because for execution of instruction that have to converted into binary codes.

Operational code is right beacause muchine instruction has two part a) operational code b) operands i.e. address in that address tell about location of operands and operational code tells about what to perform on operands.

I hope you got it.

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.

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

Operation code is the better 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 right answer.

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

What is the explaination 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.
