The word 'demo' is short for 'demonstration' and it is often used to refer to a brief presentation or sample of a product or service. For example, if you go to a store and the salesperson shows you how a new phone works, they might say "let me give you a demo". Similarly, if you are looking to buy music, you might listen to a demo version of a song before deciding to purchase it. In general, 'demo' means a preview or a sample of something that is being offered, so it can be used in a wide variety of contexts.
