Plug and Play

So, what exactly is Plug-and-Play (PnP)? PnP is a combination of the electronic computer scheme composition Input Output System (BIOS), hardw are thingmabobs, operating constitution (OS), whirl drivers, and system resources that dynamically detect and install hardware catchs that have been added to a computer system. Rather than requiring a roler to get laid and understand the technical details involved in much(prenominal) a task, PnP will automatically assign the system resources that are needed for the fresh device and will similarly rank and install the necessary driver software. In a nutshell, when connecting the new device, a substance a coach-and-fourer should be able to rhythm the computer on and use the new hardware device later on PnP installs and configures it. This concept is meant to end the days of manual device inning and driver conflicts, providing nontechnical computer users with the ability to easily ascending their computer systems. The goal was to make adding components, such as a printer or scanner, no more thorny than adding a DVD to a television; 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 communication channels. With the older ISA bus, before PNP, jumpers were formerly 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. While the PCI bus specifications do not use the condition PnP, it supports in hardware what is today called PnP. The architecture of the PC provides for sole(prenominal) a limited number of Interrupt Requests (IRQ), curb warehousing Access (DMA) channels, Input/Output (I/O) addresses, and memory regions.
