The CIR (Current Instruction Register) is a crucial component of a computer's CPU that holds the instruction currently being executed. When an instruction is fetched from memory, it is placed in the CIR before being decoded and executed by the control unit. This allows the CPU to keep track of the instruction flow and manage execution efficiently. By storing the instruction temporarily, the CIR plays a key role in the instruction cycle of the CPU.
