How Do iPods Work?

Are you interested in technology, and do you want to know how do iPods work? An iPod is one of the most exciting and revolutionary technology developments of the last two decades. It revolutionized the way that individuals listened to music, as well as the entertainment industry. Yet, few people understand the technology behind this technology. How do iPods work?

First, you need to understand exactly what an iPod is before you can understand the answer to how do iPods work. An iPod is categorized as a MP3 player, or a portable music device. MP3 files are not saved in analog form like music on a CD. However, an iPod also plays other types of files such as the ACC, WAV, AIFF, and Apple Lossless formats.

The music on iPods is saved in digital files instead. This means that the music is saved in a long stream of “0’s and 1’s” that your iPod can read. These digital files can also be played by your computer or laptop as well. The type of files that a iPod reads also means that it can hold much more music than a normal CD player.

For example, a normal audio CD can only hold approximately eight hundred megabytes of data. This translates into approximately eighty minutes of music on the audio CD. Since MP3 files are much smaller than a normal audio file, this means that iPods (and MP3 players) can hold much more music than an audio CD.

Now, that you understand a little more about the type of technology that an iPod is, and the type of technology that it uses, we can examine how they work. An iPod is able to compress files, which is part of the reason that you can store so much onto your iPod. Your iPod can compress files to one tenth the size of the regular file without sacrificing a significant loss in quality for the music.

Before an audio file is compressed by your iPod, it usually contains approximately fifty megabits worth of data depending on the size of the audio file. However, your iPod can compress this file into a five megabyte MP3 file using MP3 compression technology. Specifically, your iPod uses codecs to compress the files. 

What Is a Codec?

A codec, also known as a compressor-decompressor or a coder-decoder, is a type of device that can both encode or decode a digital data stream. Codecs can convert an audio analog into a digital analog. Thus, your iPod uses this technology when it compresses your audio (or video files depending upon the type of iPod that you have) and stores it in the iPod.

iPod File Storage

After the files are converted into a form that your iPod can use, the files are then stored your iPod’s memory. Your iPod uses a solid state memory. A solid state memory is a flash memory card (similar to the memory on a flash drive) that stores all the files.

This memory of an iPod uses small hard discs that can usually store up to eighty to one hundred and sixty gigabits worth of memory. This memory is integrated with your computer, which is how you are able to transfer new songs onto your iPod, as well as arrange songs into a playlist on your iTunes and then transfer this playlist onto your iPod.

Selecting Music on an iPod

The LCD screen of an iPod allows you to navigate through your library and select the music, or videos that you want to play. An LCD screen stands for a “liquid crystal display.” This LCD screen uses light modulating properties of liquid crystals to display information on its screen.

Finally, your iPod also has a power source which allows it to operate without being plugged in.
