plug and play
Peripheral component interface PCI slot or expansion slot can be used as plug and play if an internal USB card supporting USB version 2.0 is installed in it
Operating system
Plug-and-Play, sometimes called PnP, is a feature that many people take for granted - it is a system that attempts to detect what hardware is there upon connection and finds a way to communicate with it to make it work with the computer system. A BIOS (Basic Input/Output System) is software embedded on a chip that is responsible for starting the computer and booting an operating system.
Most wireless cards in laptops are physically removable. However, the laptop's BIOS often only allows certain wireless cards to be installed. In this case, you either need to modify the BIOS (very tricky / risky), or turn off the internal card and plug a card into a CardBus slot or USB port.

Plug 'n' Play (PnP).
BIOS has it's own set of basic I\O drivers, for example, for keyboard and monitor, sometimes the mouse as well depending on the BIOS. Once the OS is loaded, it loads it's own drivers for these devices.
digitally signed
On a laptop it is. On a desktop compuer it can be done through a fax/modem card or other expansion card. There are also models that can plug into a USB connection, with no installation necessary.
