What is the definition of draught beer and how does it differ from other types of beer?

Draught beer is beer that is served from a keg or cask, typically through a tap system. It is often fresher and has a creamier texture compared to bottled or canned beer. The main difference is in the serving method, as draught beer is dispensed directly from a keg, while other types of beer are packaged in bottles or cans.
