MP3 is a digital audio file compressed using a standard defined by the Motion Pictures Experts Group (MPEG). Officially known as "MPEG-1, Layer 3", MP3s can use as little as 10% of the storage required by the CD format. An MP3 player is a device for playing MP3 files.
MP3 players come in many sizes and capacities. The smallest MP3 players use a type of memory known as flash; unlike conventional memory such as that found in a desktop computer, flash does not lose stored information when the power is turned off. Flash is very compact and uses very little power, allowing for extremely small designs with long battery life.
