Question
2 marks
Define Instruction and instruction set.
Answer
An instruction is a binary command, and the instruction set is the complete vocabulary of commands the CPU understands.
An instruction is a highly specific, formatted binary command mathematically dictating exactly what operation the microprocessor must execute (e.g., ADD, JMP). The Instruction Set is the absolute, comprehensive dictionary of every single valid binary command (opcode) that the specific microprocessor hardware is physically engineered to recognize and execute.
