In Optics, transparency (also called pellucidity) is the Material property of allowing An analog or analogue signal is any continuous signal for which the time varying feature (variable of the signal is a representation of some other Vibration refers to mechanical Oscillations about an equilibrium point. The controller is called Dual Shock because the controller employs two vibration motors: a weak buzzing motor that feels like cell phone or pager vibration and a strong rumble motor similar to that of the Nintendo 64’s Rumble Pak.

Some third party DualShock-compatible controllers use batteries in lieu of the PlayStation’s power supply. The rumble feature of the DualShock is similar to the one featured on the first edition of the Japanese Dual Analog Controller, a feature that was removed shortly after that controller was released.
The controller was widely supported; shortly after its launch most new titles, including Crash Bandicoot: Warped, Spyro the Dragon, and Tekken 3 included support for the vibration function and/or analog sticks. Crash Bandicoot 3 Warped is a Platform game developed by Naughty Dog for the PlayStation.

When the PlayStation 2 computer entertainment system was announced, the DualShock 2 Analog Controller (SCPH-10010) included with it was exactly the same externally as the previous Dual Shock analog controller, except that it was black (colors came later), had different screw positioning (one fewer), and the DualShock 2 logo was added. Another way to tell the DualShock and the DualShock 2 controllers apart is that the connector that plugs into the console matches that console's memory card shape; the DualShock’s connector has rounded shoulders and DualShock 2’s is squared off. Internally, the Dual Shock 2 was lighter and all of the buttons (except for the Select, Start, Analog mode, L3 and R3 buttons) were readable as analog values (pressure sensitive).
