A program is a set of instructions a computer can understand. We refer to these instructions as a sequence.
A rule has two components: an event and commands (or action).
An event is a trigger that the computer recognizes and causes it to do some action
In addition to running instructions sequentially, computers are very good at repeating sets of instructions. In computer science we call this a “loop”, or code that repeats. Consider using a loop to repeat the sandwich making process: For the number of sandwiches I need: open the tuna, add mayo, stir, put on bread, put in bag.
