iPod vs. MP3 Players: What's the Difference?


PMP devices, which is short for portable music player, is a
term used to describe any digital portable music player
that allows you to download or save digital music files (in
MP3 format) from their computer to play on a PMP.
The category of PMP devices have all but replaced the
larger Walkmans and portable CD players, not only due to
their much smaller size but because you can store
hundreds or ,on some devices, thousands of songs on
them.

Today Portable Music Player devices come in all shapes.
As if we didn't have enough terminology in this category of
devices already, here is another acronym for you. Some
PMP devices, like MP3 players, are also called DAP, short
for digital audio player.

What is an MP3 Player?
An MP3 player is a type of digital audio player and falls
under the broader category of PMP devices. It's a small
(often weighing less than an ounce) handheld device that
use flash memory for storing MP3 files.

In addition to supporting the MP3 format, depending on the
brand of player you buy, it might also support additional
file types such as Windows Media Audio (WMA), Waveform
Audio (WAV), Music Instrument Digital Interface (MIDI),
Advanced Audio Coding (AAC), Ogg Vorbis and other audio
formats.

An MP3 player is basically a storage device that contains
solid-state memory, like flash memory, and software that
will let you transfer audio files from your computer to the
player. MP3 players may also include features such as
playlists, radio or Web site streaming, and basic options
like being able to choose backlight color, and equalization
options. MP3 players most commonly use the USB port on
your computer for data transfer however some may plug
into the FireWire or parallel port. Once you transfer the
music files to the player they are stored in the player's
memory. Most MP3 players are battery-powered and may
also come with an AC Adapter.

Today there are also a host of other consumer devices
which have an embedded MP3 player. Some examples
include satellite radios, smart phones, PDAs, sunglasses,
and even MP3 watches.

How Is It Different From an iPod?
The big question then is what's the difference between an
iPod and an MP3 player? The answer to that questions is
that both are MP3 players, but the iPod is a specific brand
of MP3 player, made by Apple that has a specific set of
features and design. Since the release of the Apple iPod in
2001,  under the iPod brand Apple has released many
variations of its product such as the iPod classic, iPod
Touch, iPod Shuffle, iPod Mini, iPod Nano and several
spin-off devices such as the iPod Photo. Unlike most mass
market MP3 players, the iPods use the Apple iTunes
software to transfer music to the music devices. Using
iTunes you can store a music library on your computer,
burn  music from CD, transfer photos, videos, game and
small applications (when supported by the player) and
many other features.
