Information hiding concept restricts direct exposure of data. Data is accessed indirectly using safe mechanism, methods in case of programming object. Taking bike as an example, we have no access to the piston directly, we can use ’start button’ to run the piston. You can understand the advantage of information hiding concept from this example. If a bike manufacturer allows direct access to piston, it would be very difficult to control actions on the piston.
