Explanation:
Detailed explanation-1: -Every machine instruction becomes a binary number stored in instruction memory. The binary number is separated into chunks or fields that contain information about the instruction. The field uniquely identifying the instruction as an add, a subtract, a multiply, a move, a shift, etc. is called the opcode.
Detailed explanation-2: -The types of operations include arithmetic, data copying, logical operations, and program control, as well as special instructions (such as CPUID and others).
