Presentation.
I choose MP3, because I'm interested in computer technology.
In past, we could get music from CD. The size was very huge.
Nowdays we don't need a CD player, because someone invented mp3 technology.
A principle of mp3 is this way. ( use a board )
MP3 is compression that lost information.
The size of original music file is 50 times larger than mp3.
The size of original music file is about 100 MB, but the size of mp3 is about 2 or 3 MB
It lose many data, but we can not feel the difference.
Our ears are not sensitive enough to hear that. It cannot be problem.
This is very useful. We don't need to carry huge CDplayer thanks to this technology.
The other hand, It causes problem. The problem is illegar copy of music.
We can download mp3 on internet. Many musician have damaged in property.
So, we must not use a illegar mp3 files.

Sangjun,
I think this is your summary, although you didn't write your name.
Your presentation was very informative. It is always good to hear from someone deeply interested in a subject.

Sangjun,
I don't know much about the computer technology but, I like the reproductive MP3 . It's fantastic. I can download a lot of music in my IPOD just a question. What is the different between MP3 and MP4?
