    (i) Spooling is a process that allows a computer to store data temporarily in a buffer or queue while it is being transferred from one device to another. This can be used to improve the performance of the system by allowing the computer to handle multiple input and output tasks concurrently.

    (ii) Caching is the process of storing frequently accessed data in a high-speed memory location for quick retrieval. This can improve the performance of a computer by reducing the number of times it needs to access slower storage devices.

    (iii) Buffering is the process of storing data temporarily in a buffer or queue while it is being transferred from one device to another. This can help to smooth out the flow of data and improve the performance of the system by allowing it to handle multiple input and output tasks concurrently.

    (iv) A device controller is a hardware component or software program that manages the communication between a device and a computer. It is responsible for controlling the input and output of data to and from the device and ensuring that it operates correctly.
