Q. What is Input - Output commands?

There are four kinds of I/O commands which an I/O interface can receive when it's addressed by a processor:

Control: This type of commands is device specific and is used to give specific instructions to device for example a magnetic tape requiring rewinding and moving forward by a block.
Test: This command checks status like if a device is ready or not or is in error condition.
Read: This command is helpful for input of data from input device.
Write: this command is employed for output of data to output device.
