A cassette is a small rectangular box that holds a thin strip of tape. This tape can have music, sound recordings or movies on it, and can be played in a special machine called a cassette player. Cassettes used to be very popular in the past, but now they have been replaced by CDs and digital files. So you might hear the word "cassette" when people are talking about something that was popular in the past, or when they are comparing old technology to new technology.
