Examples of things that are digital include CD’s and DVD’s, music referred to as MP3’s, most new televisions, computers, and more!
ExplorationBack in the day!
Before digital technology was invented, many things worked differently! For example, before people started using CD's and MP3's to listen to music, they listed to cassette tapes and records! And before movies were watched on DVD's, they were stored on something called VHS tapes!
Find out if your parents or grandparents still have any of these older things in the house. Ask them to show you the tapes or records. What are some of the differences and similarities that you notice? If the old tapes or records still work, try watching or listening to them. Do you notice a difference in what you see or hear?
