plug-in machine is a plug-in device. It is a computer hardware device that can expand and upgrade the hardware functions by plugging and unplugging external plug-ins. It can increase the input, output, storage and other functions of the computer, and can also improve the performance of the computer. Plug-in machines usually use standardized interfaces, such as PCI interfaces, ISA interfaces, AGP interfaces, etc., and perform data transmission by connecting to corresponding slots or interfaces.
