Question

which of the following contains the instruction register?
control unit
arithmetic/logic unit
auxillary storage device
ram

Explanation:

The control unit fetches instructions from memory, decodes them, and manages the execution of instructions. The instruction register is part of the control unit and holds the currently executing instruction. The arithmetic/logic unit (ALU) performs arithmetic and logical operations. Auxiliary storage devices (like hard drives) store data long - term. RAM (Random Access Memory) is volatile memory for temporary data storage. ROM (Read - Only Memory) stores firmware and non - volatile data.
