The Galaxy Tab utilizes a capacitive (c-type) touchscreen that responds to the user's input through body contact.
Other touchscreen technology like resistive (r-type), respond via pressure points. For r-type, the touchscreen must be calibrated properly. With c-type, this is no longer needed because it uses a different technology to distinguish the touchpoints being used.
Note: The Galaxy Tab also supports multi-touch, thus method like pinch & zoom can be used in a web browser.
