Discs
The PlayStation 2 features a pop-out tray on which disc games are loaded. The discs then connect and spin over a built-in DVD laser lens that can also read CDs, DVDs, and original PlayStation games.
Controller Ports
The front of the PlayStation 2 features two serial controller ports that are compatible with both PlayStation and PS2 controllers. A PS2 controller expansion bay can plug in to one of the controller ports to make the system compatible for eight-player games.
Expansion Bay
The back of a PS2 features an expansion bay that a hard drive or Ethernet connection can snap onto. The expansion bay is covered by a plastic piece that is pulled off using a flathead screwdriver.
CPU
The system runs at 299 MHz with a chip that has 64-bit graphics processing. The CPU chip is known as the Emotion Engine and is located internally on the system. It also uses a GS graphics card to help render and display games.
Cords
The PlayStation 2 requires two cords to power and connect to a television. The basic power cord plugs into the back of the PS2 and plugs into any standard outlet. The A/V cord is an RCA cord with a special connection to the PS2 and three cables for the television (two audio and one video).
