Quizplus · Accepted Answer

The memory address of the first instruction is stored in a pointer within the control unit of the microprocessor. A pointer is a variable that stores the memory address of another variable or data in the computer's memory. Option A, index, typically refers to a numerical value used to access elements within an array, and is not used in this context. Option B, variable, refers to a storage location in memory with a specific value, but does not describe the memory location of the first instruction. Option D, constant, refers to a value that does not change during program execution, and is not related to the memory location of the first instruction.
