The system file allow-io.sys, known as Allow IO software is identified as a Windows driver. It is a small software program allowing users to communicate with connected devices and hardware. This driver allows easy communication of the user with T-POD using the parallel port on user PC. It also let windows control all user hardware (printer, sound card, CDROM, modem, keyboar, mouse, etc). Updating the driver will improve system performance and stability of the user PC. Since it operates at speeds that may not be congruent with the operating system, the communication between the two is done primarily through I/O (input and output) request packets (IRPs). These packets are like network packets or Windows message packets. They are passed from OS to a specific driver then one after another. IRPs go from a driver to another in the same stack to facilitate communication. The stack is composed of joystick driver, USB host controller, USB hub and the PCI bus. The communication is coordinated when each driver send and receive IRPs in the stack.

A process usually a part of an installed application such as Windows Allow I/O Driver, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.
