The term plug and play has now been expanded to a massive variety of application where the same lack of user setup is applied. Expansion hardware devices are controlled and exchange data with the host system through defined memory or I/O spaceport addresses, interrupt request lines, direct memory access channels, and other mechanisms, that must be related with a particular device to operate. Most of the computers have a unique combination of these resources to each slot of a motherboard.
