We all know the iPod, if you don't know of it, you must be from another planet and wouldn't be interested in this article anyways. If you are thinking about buying an iPod or already own one and interested in how it works, here you go.

The iPod Rocks!

The iPod is usually categorized as a portable music device that among other things play music files such as MP3's. MP3's are digital files that can be played on most computers today. Music is not saved in analog form; instead it is saved in digital form, and stored on a hard drive or flash memory unit or in the case of the iPod a miniature digital hard drive. It should be noted that besides the ability to play MP3's, most iPod's can play AAC, WAV, AIFF, Apple Lossless and Audible 2, 3 and 4 formats.

I am sure you have some, or used to have some audio CD's right? Well a CD can hold about 80 minutes of music, which isn't very much.

How does the Apple iPod fit hours upon hours of music in such a small amount of space? The answer is compression.

The iPod can fits so much music because of the codecs that it uses to compress the MP3's or other digital audio files. Codecs are compression decompression algorithms and are formulas that allow you to shrink the size of large files into very small and manageable files. The iPod is able to read these shrunken files and create high quality audio files out of them, which in turn play the sound to your earpiece and let you enjoy the music.

Today, there are many different types of iPod's available. They can include traditional iPod's, video iPod's, the iPod Nano and the iPod Shuffle. These different types of iPods usually use one of two types of storage; miniature hard drives or flash memory.

Miniature hard drives can be smaller than 2 inches and fit as much as 80 gigabytes of data, making it extremely easy to store your entire music collection and download several full length motion pictures. On smaller sized units such as the iPod Nano and iPod Shuffle a different type of storage media is used, it is called flash memory. This type of storage unit usually holds from 1 to 8 GB of data. The advantage of using flash memory is that it is even smaller than miniature hard drives and extremely thin, allowing an even smaller device to be created.

How do you get music onto your iPod?

For the most part, transferring audio and video files to your iPod is extremely easy and convenient. There are two main ways that most people transfer files to their iPod; using iTunes and transferring their MP3 or other files from their computer.

iTunes is Apple's music and video store that sells digital files that users can download. These files come in a format called AAC and include DRM (Digital Rights Management) so that there are limitations on how you use these files. Usually your iPod can easily synch up with iTunes with the help of your computer and transfer the music from the iTunes site off the internet directly to your iPod through the use of a USB cable.

For those people that already have CD's or MP3's on their home computer, your iPod also plays these types of files. You can easily synch your iPod up with your home computer or computing device and send these files from one device to another. It should be noted that depending on the type of iPod you own, you can transfer music files, view music videos, TV shows, full length motion pictures and even digital photos.
