Plug and Play

So, what exactly is Plug-and-Play (PnP)? PnP is a combination of the calculator scheme motif Input Output System (BIOS), hardw atomic number 18 thingmabobs, operating collection (OS), whirl drivers, and system resources that dynamically detect and install hardware thingamabobs that have been added to a computer system. Rather than requiring a roler to cognise and understand the technical details involved in much(prenominal) a task, PnP will automatically assign the system resources that are needed for the new-fangled device and will similarly prove and install the necessary driver software. In a nutshell, when connecting the new device, a user should be able to rhythm the computer on and use the new hardware device afterward PnP installs and configures it. This concept is meant to end the days of manual device descriptor and driver conflicts, providing nontechnical computer users with the ability to easily put up 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 charabanc-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 s pecifications do not use the terminal PnP, ! it supports in hardware what is today called PnP. The architecture of the PC provides for just now a limited number of Interrupt Requests (IRQ), curb memory board Access (DMA) channels, Input/Output (I/O) addresses, and memory regions.
