Plug and Play (PnP) is a computer feature that allows a device to be connected to a system and be automatically detected, configured, and ready for use with minimal or no user intervention. When a new hardware device like a keyboard, mouse, or printer is plugged in, the operating system identifies it, finds and installs the necessary drivers, and sets it up for use. This technology simplifies hardware installation, eliminating the need for manual configuration like setting jumpers or dip switches.

How Plug and Play works

Device detection: When a device is connected, the system detects its presence.

Device identification: The system identifies the device's specifications.

Driver installation: The operating system automatically locates and installs the correct driver software needed for the device to function.

Configuration: The system configures the device's resources, allowing it to communicate with the computer.

Benefits

Ease of use: Users can simply plug in a new device and start using it almost immediately.

Reduced complexity: It eliminates the need for users to have in-depth technical knowledge for hardware setup.

Efficiency: It saves time by automating the setup process, which was previously a complex and multi-step procedure.
