<                    Checks if the value of left operand is less than the value of right operand. If yes, then the condition becomes true.                              (A < B) is true

>=                 Checks if the value of left operand is greater than or equal to the value of right operand. If yes, then the condition becomes true.                  (A >= B) is not true.
