The leading family of games consoles, from Sony Corporation consisting of the original Playstation (PS1) and the Playstation 2 (PS2). The basic Playstations consist of a small box containing the processor and a DVD reader, with video outputs to connect to a TV, sockets for two game controllers, and a socket for one or two memory cards. The PS2 also has USB sockets. The PS2 can run PS1 software because the PS2's I/O processor is the same as the PS1's CPU.
