Plug and Play

So, what exactly is Plug-and-Play (PnP)? PnP is a combine of the reckoner scheme composition Input Output establishment (BIOS), ironw are thingmabobs, operating organisation (OS), whirl device drivers, and system resources that dynamically detect and install hardware whatsiss that have been added to a reckoner system. Rather than requiring a roler to have a go at it and understand the technical detail involved in such(prenominal) a task, PnP will mechanically assign the system resources that are needed for the stark naked device and will similarly post and install the necessary driver software. In a nutshell, when connecting the newfound device, a substance abuser should be able to rhythm the figurer on and use the new hardware device later PnP installs and configures it. This concept is meant to end the eld of manual device material body and driver conflicts, providing nontechnical computer users with the ability to easily get up their computer systems. The goal was to take on adding components, such as a printer or scanner, no more thorny than adding a DVD to a picture; 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 communicating channels. With the older ISA bus, before PNP, jumpers were in one case 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. enchantment the PCI bus specifications do non use the term PnP, it supports in hardware what is today called PnP. The computer architecture of the PC provides for moreover a limited number of foil Requests (IRQ), curb Memory retrieve (DMA) channels, Input/Output (I/O) addresses, and retrospect regions.
