Introduction to PlayStation 2:

[Edit this paragraph]

PlayStation 2, called PS2 for short, is a domestic 128-bit game machine made by SCEI (Sony Computer Entertainment Inc.), a subsidiary of Sony Corporation of Japan, which was launched on March 4th, 2000. On the day it was listed in Japan, it caused a buying craze. In 2004, the ultra-thin PS2 console (named PlayStation Two, compared with the mini version of PS-PlayStation One) went on the market in the world. By August 29th, 2006, the global sales volume had exceeded 654.38+065.438+million units.

In China, the marketing slogan of Sony (China) is: △××□, feel the feeling of PS. In Taiwan Province Province, Sony Computer Entertainment (Taiwan Province Province) focuses on "this one", emphasizing not only playing games, but also playing DVDs.

The competing products of PlayStation 2 in the same period are:

Sega's DC

Microsoft Xbox

Nintendo's NGC and WII (in terms of price)

Other meaning of PS2:

PS/2 is one of the common interfaces on early computers, which is used for mouse, keyboard and other devices. Generally speaking, the mouse of PS/2 interface is green and the keyboard is purple.

PS/2 interface is an input device interface, not a transmission interface. Therefore, PS2 port has no concept of transmission rate at all, only scanning rate. In Windows environment, the sampling rate of ps/2 mouse is 60 times/second by default, and that of USB mouse is 120 times/second. A higher sampling rate can theoretically improve the movement accuracy of the mouse.

PS/2 interface devices do not support hot plug, and forced hot plug may burn the motherboard.

PS/2 can interoperate with USB interface, that is, PS/2 interface devices can be converted into USB, and USB interface devices can also be converted into PS/2.

In July, 2008, Shenzhen PS2 merchants quoted: 1 100 to 1280.

At present, PS2 is the most cost-effective game console, which supports the most games. Domestic cracking technology has also been put in place, which can basically be done by video game shopkeepers.

Moreover, there are few faults and many external accessories.
