The X-sync is the socket on an external flash that ensure that the flash will go off when the shutter opens. This begs the question, external flash?!
The in camera flash isn't a great flash... It tends to be very close to your subject and often washes out your photo. Some cameras do enable you to control not only turning it on or off, but also the percentage of brightness. And, of course, you can always utilize various tools to try to defuse the light from the flash, to soften it.
But, generally, a photographer may want to utilize external flash. An external flash can be attached to your camera as needed and many come with the ability to focus the light either on the subject (disfused or not) or to focus the light on another object, such as a wall or white sheet, which will enable the lit to bounce off and hit the subject in a softer, less direct manner.
You can also utilize multiple flash units (attached to the camera or not) which can give a photographer, for example, backlight. In this case, the X-sync would enable the flash to go off in a timely manner to coincide with the shot.

Interesting--I'd never heard the term n X-sync before. Always handy to have the right word in your pocket!
