"Plug and Play" refers to a technology that allows devices to be connected to a computer or system without requiring complex setup or configuration. When a compatible device, such as a USB drive or printer, is plugged into a port, the system automatically recognizes it and installs any necessary drivers, enabling immediate use. This concept simplifies the user experience, making it accessible for people without technical expertise. It is commonly used in various devices, including smartphones, gaming consoles, and home appliances, allowing users to easily expand their technology without needing extensive knowledge or assistance.
