How is an MP3 player related to a computer?

An MP3 player—an electronic device that weighs less than one ounce (28 grams)— allows music to be copied from the Internet, organized, and stored into a computer’s memory. An MP3 player plays MP3 files, a compressed digital audio file. With an MP3 player, like Apple’s iPod®, a consumer can create personalized music lists and carry thousands of songs wherever he or she goes.

Tiny MP3 players allow us to carry thousands of songs with us everywhere we may go.
