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

Programs written for the Apple operating systems are distinguished from software created for other operating systems in that it must be approved by Apple for use on its devices, whether it is from Apple (Final Cut, iWork, Keynote, Logic Pro and GarageBand are popular titles), or is a third party application from Parallels, Nuance, Microsoft and Amazon, among many others.

Apple Software

Apple devices including Macs, iPhones, iPods and iPad support standard wired and wireless networking technologies, but they also utilize custom applications and some special techniques for networking with each other and with non-Apple devices. Apple manufacturers the AirPort line of wireless networking products, and has its own networking protocols, AppleTalk and AFP (Apple Filing Protocol).

A miscellany is defined as a "collection of various pieces of writing by different authors", but it has come to mean something "Of items gathered or considered together of various types or from different sources" or "a collection or group composed of members or elements of different kinds". The word "miscellaneous" comes from the Latin word "miscere", meaning "to mix." You might have heard the expression "a mixed bag," which applies when you don't quite know what you're going to get. More commonly, a miscellaneous group is made up of an odd group of things that don't fit anywhere else.
