What does "plug and play" refer to in computing?

"Plug and play" refers to devices that automatically operate with the included drivers once they are connected to a computer or other host devices. This feature enables users to easily add new hardware to their system without the need for complex installation procedures or manual configuration. When a plug and play device is connected, the operating system recognizes it and loads the necessary drivers automatically, allowing for immediate usability.

This ease of use is a significant benefit for users, as it streamlines the process of integrating new hardware into existing setups. Examples of common plug and play devices include USB flash drives, modern printers, and external hard drives. Such devices enhance user experience by eliminating the knowledge barrier often associated with hardware installation, making technology more accessible to individuals without extensive technical expertise.
