What is an MP3 Player?
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, like mp3 players, with long battery life.
The limitation of flash-based mp3 players is that they do not have a great deal of storage capacity. For larger storage needs, hard disk-based mp3 players were developed. These mp3 players can have storage capacities in the tens of thousands of songs, but sacrifice the ultra compactness of flash-based mp3 players. Hard disk-based mp3 players are also generally more expensive than flash-based mp3 players.
With an mp3 player in hand or pocket, a consumer can create personalized music lists and carry thousands of songs wherever they go. All of that stored music and the mp3 player itself fit into a device that, in some cases, weighs less than one ounce. Portability is a large factor in the popularity of the mp3 players, considering the ease of transportation in comparison to other devices.
