How an iPod works - Essay Example You want to know more about this Ipod, but are overwhelmed by the technical jargon of MP3 and DMZ protocol. Yet, under that veil of secrecy lies a simple device that requires only a simple understanding. The Ipod is a three-step process of getting an input, looking for some human interface, and giving an output. Long before you listen to a song on your Ipod, a studio somewhere on the West Coast had disassembled the song and broken into small pieces waiting to be purchased. They take these pieces and squeeze them down and compress them into small packets called the MP3 format. When you order this song it is quickly thrown into a delivery system called a download. The packets come through the Internet, into your computer, out to your Ipod, and are stored in a box called memory. The squeezed packets, under great pressure, will sit and wait until their next calling. The song that was broken up only moments ago has buried itself deep within your machine through a step called input. The input sits in the box and waits for the human interface. In the world of Ipod, the output is the small brain, the human is the big brain, and the input is no brain at all. Here in the 2nd step the Ipod waits for human control. The big brain kicks in and presses the right buttons, it locates the mood, and navigates to the proper memory box. The big brain sets the tone, volume, and play list.
