    1. Managing data transfer: I/O device controllers are responsible for managing the transfer of data between the device and the computer. This involves receiving data from the device, buffering it if necessary, and sending it to the appropriate location in the computer’s memory.
    2. Controlling device operation: I/O device controllers also manage the operation of the device itself, ensuring that it functions correctly and performs the tasks it is designed to do. This may involve sending commands to the device or adjusting its settings as needed.
    3. Providing device drivers: In some cases, I/O device controllers may also provide device drivers, which are software programs that allow the computer to communicate with the device. Device drivers are often specific to a particular device or type of device and are necessary for the computer to be able to use the device.
    4. Error handling: I/O device controllers are also responsible for detecting and handling errors that may occur during the transfer of data or the operation of the device. This may involve retrying failed data transfers or issuing error messages to the user.
