the dot ball is a ball in which no run(s) scored
A six is scored when the ball goes over the boundary rope without touching the ground. A four is when the ball crosses the rope with one or more bounces before reaching the rope.

Runs are scored by the batting team by hitting the ball. The batsmen can try and hit 6's or 4's. even if you don't hit a boundary you can still run 1,2,3,4,etc it is wise to stop running when the ball is close to the wicket.
A dot represents a ball bowled from which no runs are scored
By hitting the ball over the boundary without the ball touching the ground before hand. If the ball touches the ground before the boundary but goes over it, it scores four.
