Difference between Distance & Displacement

Displacement is a vector quantity as it is associated with direction,but distance is a scalar quantity which does not give any information about direction of motion.Distance and displacement magnitude are numerically equal only when the body travels in a straight line from A to B(i.e the shortest distance from a point to another). Also distance has always a non-zero magnitude,but displacement can be zero if the body returns to the point of origin at the end of motion.
