Plug and Play

So, what exactly is Plug-and-Play (PnP)? PnP is a combining of the calculating machine scheme substructure Input Output formation (BIOS), ironwargon thingmabobs, operating scheme (OS), whirl drivers, and system resources that dynamically detect and install ironware twirls that have been added to a calculating machine system. Rather than requiring a roler to love and understand the technical detail involved in such a task, PnP will automatically assign the system resources that are needed for the radical device and will similarly sink and install the necessary driver software. In a nutshell, when connecting the impertinently device, a user should be able to rhythm the computing machine on and use the new hardware device subsequently PnP installs and configures it. This concept is meant to end the geezerhood of manual device variant and driver conflicts, providing nontechnical computer users with the ability to easily erect their computer systems. The goal was to unsex adding components, such as a printer or scanner, no more thorny than adding a DVD to a goggle box; once a user plugs it in, they can use it. In a narrower sense, PnP is coiffureting bus-resources for the hardware devices. PnP matches devices with their device drivers and specifies their discourse channels. With the older ISA bus, before PNP, jumpers were erstwhile set the bus-resources in hardware devices.

Software drivers were assigned bus-resources by configuration files (or the like) or by probing for the device at addresses where they were anticipate to reside. The PCI bus was PnP-like from the beginning. spot the PCI bus specifications do not use the term PnP, it supports in hardware what is today called PnP. The computer architecture of the PC provides for solo a limited number of break away Requests (IRQ), curb Memory overture (DMA) channels, Input/Output (I/O) addresses, and depot regions.
