MP3 Players
An MP3 player is a digital audio player that store and play audio files. Most of the audio files people save on them are music, though some people also store speeches or files of conversation as well. There are two basic types of MP3 players—flash-based players and hard-drive based players. Flash-based players rely on external sources for memory. In other words, users need to insert memory sticks or memory cards into flash-based MP3 players in order to have audio files available to play on the player. Hard-drive based MP3 players, on the other hand, store all audio files on the actual MP3 unit. One of these players can store thousands of songs. Either type of MP3 player can be good—it really comes down to personal choice MP3 is the dominant audio format format, and is nearly universally supported. The main alternative formats are AAC and WMA. Unlike MP3, these formats support DRM restrictions that are often implemented into files from paid download services. Open source formats, which are completely patent-free, are available - though less widely supported. Examples include Ogg Vorbis, FLAC, and Speex. Finally, a recent newcomer is MPEG 4, which is quickly starting to receive adoption by several digital audio players.
Types of MP3 Players
An MP3 player is generally categorized by the storage media that it contains:
* Flash-based Players: These are non-mechanical solid state devices that hold digital audio files on internal flash memory or removable flash media called memory cards. Due to technological advancements in flash memory, these originally low-storage devices are now available commercially ranging up to 32 GB. Because they are solid state and do not have moving parts they require less battery power and may be more resilient to hazards such as dropping or fragmentation than hard disk-based players. Basic MP3 player functions are commonly integrated into USB flash drives.
* Hard drive-based Players or Digital Jukeboxes: these are devices that read digital audio files from a hard disk drive (HDD). These players have higher capacities currently ranging up to 1 TB. At typical encoding rates, this means that thousands of songs – perhaps an entire music collection – can be stored on one player.
* MP3 CD Players: Portable CD players that can decode and play MP3 audio files stored on CDs or DVDs.
* Networked audio players: Players that connect via (WiFi) network to receive and play audio.
