Micro-DVI The Micro-DVI port is a proprietary video output port found in the original MacBook Air. It is smaller than the Mini-DVI port used by its MacBook models. To use the port for displaying video on a standard monitor or television, an adapter must be used. Both a Micro-DVI to DVI adapter and a Micro-DVI to VGA adapter were bundled with the original MacBook Air. A Micro-DVI to Video adapter, which provided composite and S-video outputs, was also sold separately. The Micro-DVI to DVI adapter is only compatible with a DVI-D (digital) signal; DVI-A and DVI-I signals do not work as they do not have the required analog connections. The Micro-DVI connector was replaced with the Mini DisplayPort connector starting with the Late 2008 MacBook Air.
Apple A5 The Apple A5 is a 32-bit system-on-a-chip designed by Apple Inc. and manufactured by Samsung and is the successor to the Apple A4. The A5 commercially debuted with the release of Apple's iPad 2 tablet, and also powers the iPhone 4S, iPod Touch fifth generation, Apple TV third generation, and the iPad mini. This is consistent with how Apple debuted the A4 chip: first in the original iPad, followed by the iPhone 4, and then the iPod Touch (fourth generation). Apple claims that compared to its predecessor, the A4, the A5 CPU "can do twice the work" and the GPU has "up to nine times the graphics performance".
