Detailed explanation-1: -Each instruction has two parts: one is the task to be performed called the operation code (opcode) and the other is the data to be operated on called the operand (data).
Detailed explanation-2: -Opcodes and operands The opcode is the instruction that is executed by the CPU and the operand is the data or memory location used to execute that instruction.
Detailed explanation-3: -An instruction format defines the different component of an instruction. The main components of an instruction are opcode (which instruction to be executed) and operands (data on which instruction to be executed).
Detailed explanation-4: - An instruction is a binary pattern designed inside a microprocessor to perform a specific function. The entire group of instructions that a microprocessor supports is called Instruction Set.
Detailed explanation-5: -Operands are definite elements of instructions that specify the data on which operation is to be done. In general, each instruction code is 16-bit and consists of three parts called fields, which include the mode, the opcode, and the address.
