We people every body know that playstation is the gameming device not only kids it’s for every aged pople.So, Play station is my favourite device. PlayStation 2 software is distributed on CD-ROM and DVD-ROM. In addition the console can play audio CDs and DVD movies, and is backwards compatible with PlayStation games. The PS2 also supports PlayStation memory cards and controllers, although original PlayStation memory cards only work with original PlayStation games and the controllers may not support all functions(such as analog buttons) for PS2 games.
The standard PlayStation 2 memory card has an 8 MB capacity. There are a variety of non-Sony manufactured memory cards available for the PlayStation 2, allowing for a memory capacity larger than the standard 8 MB.
The console also features USB and IEEE 1394(Firewire) expansion ports. A hard disk drive can be installed in an expansion bay on the back of the console, and is required to play certain games, notably the popular Final Fantasy XI.[28] This is only available on certain models.
The hardware uses the custom-designed Emotion Engine CPU, with a floating point performance of 6.2 GFLOPS, and the custom-designed Graphics Synthesizer GPU, with a fillrate of 2.4 gigapixels/second, capable of rendering up to 75 million polygons per second.[29] When accounting for features such as lighting, texture mapping, artificial intelligence, and game physics, it has a real-world performance of 3 million to 16 million polygons per second.[29][30]
The PlayStation 2 may natively output video resolutions on SDTV and HDTV from 480i to 480p while other games, such as Gran Turismo 4 and Tourist Trophy are known to support up-scaled 1080i resolution[31] using any of the following standards: composite video(480i), S-Video(480i), RGB(480i/p), VGA(for progressive scan games and PS2 Linux only), YPBPR component video(which display most original PlayStation games in their native 240p mode which most HDTV sets do not support), and D-Terminal. Cables are available for all of these signal types; these cables also output analog stereo audio. Additionally, an RF modulator is available for the system to connect to older TVs.
Digital(S/PDIF) audio may also be output by the console via its TOSLINK connector which outputs 5.1 channel sound.
