Question

Which of the following is not a register?

• A. Accumulator
• B. Cursor
• C. Stack pointer
• D. Program counter

Hint:

Registers are used in CPU for temporary storage, while the cursor is just a pointer on the screen.

Answer 1

The Correct Option is B

A register is a small, fast storage location in a CPU. The options "Accumulator", "Stack pointer", and "Program counter" are all registers, used for specific tasks such as storing intermediate values, addresses, or program execution status. The "Cursor" is not a register, but rather a visual indicator on the screen.
Thus, the correct answer is \( \text{Cursor} \).
