Mac OS X is the desktop operating system from Apple Inc., found on Macintosh computers. OS X consists of a Mach/BSD-based kernel, operating system interfaces primarily based on FreeBSD and additional frameworks (written in C, C++ and Objective-C providing user interface and application-level services.

Mac OS X

All of Apple's hardware is produced solely by Apple Inc., who determines internal systems, designs, and prices. Apple buys certain components wholesale from third-party manufacturers. The current Mac product family uses Intel x86-64 processors. All Mac models ship with at least 1 GB RAM as standard. Current Mac computers use ATI Radeon or nVidia GeForce graphics cards and include a dual-function DVD and CD burner, called the SuperDrive. Current Apple hardware includes the iPad, iPhone, iMac, Mac Pro, Macbook, iPod and Apple TV. Discontinued hardware includes the Apple I, Apple II, and the Apple III, the Lisa, the Newton, the Quadra, Performa, Centris, Macintosh II and LC series, the Power Macintosh, iBooks and the MacBook.

Apple Hardware

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.

Apple OS

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
