What is iPod Nano

The iPod Nano (trademarked, marketed, and stylized as iPod nano) is a portable media player designed and marketed by Apple. The first generation of the iPod Nano was introduced in the end of 2005 as a replacement for the iPod mini. It uses flash memory, like the iPod Shuffle, but with a 56 millimetres (2.2 in) QVGA display on the latest model, and the "click wheel" found on the iPod Classic. The iPod Nano has gone through five models, or generations, since its introduction. The fifth generation (current) supports FM radio, video recording, a microphone for voice memos, a pedometer, and a slightly larger screen than that of the previous generation.
