Plug-and-Play (PnP) is a standard way of configuring PC-compatible computer hardware automatically. Developed by Microsoft and other companies in the mid-1990s, PnP simplifies the process of adding new hardware to a computer by allowing the operating system to detect and install devices automatically.
Universal Serial Bus (USB) is a standard interface used for connecting peripherals to computers and other devices, offering improved data transfer rates and ease of connectivity as compared to earlier technologies like parallel ports.
