Reversible computing

Reversible computing is a way of doing calculations in computers that allows us to undo what we've done. Imagine that you are playing a game of chess - when you make a move, you can always go back and take that move away. Reversible computing works in the same way. Instead of deleting the information each time a calculation is made, it stores the data in a "reversible" way so that the information can be undone. This helps save energy and can make calculations faster.
