Plug & Play

Dedicated hardware are devices with built-in games. They are usually connected to a TV via cables, and may be powered by batteries. The Plug & Plays are a subset of dedicated hardware which are usually identified for being only a controller which are connected directly to the TV. Some dedicated hardwares have a cartridge/expansion slot, making them very similar to a standard console, but this is not their main purpose of being a self-contained device.
