what is the term which differentiate the Apple A7 and Apple A8 system on a chips?
Apple A7 The Apple A7 is a 64-bit system on a chip (SoC) designed by Apple Inc. It first appeared in the iPhone 5S, which was introduced on September 10, 2013. Apple states that it is up to twice as fast and has up to twice the graphics power compared to its predecessor, the Apple A6. While not the first 64-bit ARM CPU, it is the first to ship in a consumer smartphone or tablet computer.
Apple QuickTake The Apple QuickTake (codenamed "Venus", "Mars", "Neptune") is one of the first consumer digital camera lines. It was launched in 1994 by Apple Computer and was marketed for three years before being discontinued in 1997. Three models of the product were built including the 100 and 150, both built by Kodak; and the 200, built by Fujifilm. The QuickTake cameras had a resolution of 640 x 480 pixels maximum (0.3 Mpx). The 200 model is only officially compatible with the Apple Macintosh for direct connections, while the 100 and 150 model are compatible with both the Apple Macintosh and Microsoft Windows. Because the QuickTake 200 is almost identical to the Fuji DS-7 or to Samsung's Kenox SSC-350N, Fuji's software for that camera can be used to gain Windows compatibility for the QuickTake 200. Some other software replacements also exist as well as using an external reader for the removable media of the QuickTake 200.
