Different settings can be applied for when the machine is running off a charger, battery, UPS, or all three. The appropriate flags are as follows: -c (charger), adjust settings used while connected to a charger-b (battery), adjust settings used when running off a battery-u , adjust settings used when running off a UPS
It is referred to as non-volatile memory or NVRAM because, after the system loses power, it does retain state by virtue of the CMOS battery. When the battery fails, BIOS settings are reset to their defaults. The battery can also be used to power a real time clock (RTC) and the RTC, NVRAM and battery may be integrated into a single component ...
Boot Camp Assistant is a multi boot utility included with Apple Inc.'s macOS (previously Mac OS X / OS X) that assists users in installing Microsoft Windows operating systems on Intel-based Macintosh computers.
The updated MacBook Pro 13- and the 15-inch would each have up to a claimed 7 hours of battery life, while the 17-inch would keep its 8-hour capacity. [32] [34] Some sources even reported up to eight hours of battery life for the 13- and 15-inch MacBook Pro computers during casual use, [35] while others reported around six hours. [27]
The 15-inch MacBook Pro weighs the same as the 15-inch aluminum PowerBook G4, but is 0.1 inches (0.25 cm) deeper, 0.4 inches (1.0 cm) wider, and 0.1 inches (0.25 cm) thinner. [7] Other changes from the PowerBook include a built-in iSight webcam and the inclusion of MagSafe, a magnetic power connector designed to detach easily when yanked.
The Mac Pro Server includes an unlimited [8] Mac OS X Server license and an Intel Xeon 2.8 GHz quad-core processor, with 8 GB of DDR3 RAM. [114] In mid-2012, the Mac Pro Server was upgraded to an Intel Xeon 3.2 GHz quad-core processor.

The MacBook and the 13-inch MacBook Pro use a 60 W MagSafe charger, whereas the 15- and 17-inch MacBook Pro use an 85 W version. The MacBook Air used a lower-powered 45 W version. According to Apple, an adapter with a higher wattage than that originally provided may be used without problems. [12]
In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors.These MOS capacitors, the basic building blocks of a CCD, [1] are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges.
