What is Programmed I/O: How the CPU communicates with other hardware

The computers CPU uses Programmed I/O to communicate with other hardware. Using this technique, hardware is addressed in a similar way to how memory is addressed, instead of a Memory Address Register, I/O devices use a I/O Device Register. Data that is intended to be read or written to I/O devices is communicated via an I/O data register. These registers are within the controllers for the devices.
