what is an ipod


An iPod is a portable device designed by Apple Computer which is used for storing and playing audio files encoded by MP3 or AAC compression algorithms. iPods have distinctive styling and can hold anywhere from a few hundred to ten thousand songs.

The iPod is a combination portable digital media player and hard drive from Apple Computer. The original version was about the size of a deck of playing cards, with a monochrome screen and a 5 gigabyte capacity. iPods can be now be purchased with up to 60 GB of hard drive capacity and color screens capable of playing television shows, videos or movies uploaded from a PC.
An iPod can be connected to a computer with either a FireWire or USB port, with many of the latest versions depending upon USB 2.0. iPods have a reputation for being user-friendly. Users navigate with what Apple calls a “touch wheel,” a centrally-placed circular disk designed for one-hand operation. Popular iPod features include a calendar, address book, to-do list, alarm clock with sleep timer, games and text reader. A large variety of peripherals exist for the iPod beyond its iconic white ear buds, including modules that allow songs to be broadcast on radio frequencies, docks for digital cameras, digital voice recorders and docking stations that are integrated with stereo systems, powered speakers or even automobile entertainment systems.

While the iPod was originally platform dependent, after July 2004 iPods (and Apple’s iTunes software, included with each unit) worked on either Windows or Mac. iTunes makes it possible to load an entire CD onto an iPod in as little as ten seconds, organize thousands of songs into favorite playlists, purchase songs, albums, videos and movies from the online store and subscribe to podcasts.

The iPod supports most audio file formats including MP3, wav, and AAC. As of October 2006, the iPod was the world’s most popular portable digital media player, with more than 60 million units sold worldwide
and A USB flash drive is a NAND-type flash memory data storage device integrated with a USB (universal serial bus) connector. USB flash drives are typically removable and rewritable, much shorter than a floppy disk (1-4 inches or 25-102 mm), and weigh less than 2 ounces (56 g). Storage capacities typically range from 64 MB to 32 GB[1] or more. Some allow 1 million write or erase cycles[2][3] and have 10-year data retention,[4] connected by USB 1.1 or USB 2.0 or both. USB Memory card readers are also available, whereby rather than being built-in, the memory is a removable flash memory card housed in what is otherwise a regular USB flash drive, as described below.
