How MP3 Music Files Work
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a patented
digital audio encoding format using a form of lossy data compression. It is
a common audio format for consumer audio storage, as well as a de facto
standard of digital audio compression for the transfer and playback of music
on digital audio players. MP3 is an audio-specific format that was designed
by the Moving Picture Experts Group.
The word's primary usage comes in the form of a verb. Increasingly,

FTP is a standard network protocol used to exchange and manipulate files
over an Internet Protocol computer network. FTP is built on a client-server
architecture and utilizes separate control and data connections between
the client and server applications. Client applications were originally
interactive command-line tools with a standardized command syntax, but
graphical user interfaces have been developed for all desktop operating
systems in use today. FTP is also often used as an application component
to automatically transfer files for program internal functions.
