QUICKTIME
This is a multimedia technology developed by our friends at Apple Computer. It is a popular format for creating and storing sound, graphics, and movie (.mov) files. Though it is an Apple technology, QuickTime software is available for both the Mac and the PC. If you don't have QuickTime on your computer, or if you want to see if you have the latest version, check out Apple's QuickTime site.

QWERTY
This term is used to describe a standard (Latin alphabet-based) keyboard. Why? Because the first six keys in the upper-left part of the keyboard spell out Q-W-E-R-T-Y. I suppose you could call it a QWERTYUIOP keyboard, but QWERTY is a lot easier to say. In case you are wondering why the QWERTY keyboard is arranged like it is, the original reason was to reduce the jamming of typebars in typewriters as they moved to strike the paper.
In 1932, August Dvorak developed what was intended to be a more efficient keyboard, in which he placed the vowels and the five most common consonants in the middle row, based on the idea that an alternating rhythm would be established between the right and left hands. Though the keys on the Dvorak keyboard were more efficiently arranged, it was and still is too much of a pain for people to switch from the familiar QWERTY arrangement. So, it looks like we're stuck with what we have. Sorry Dvorak.

QUAD-CORE
Quad-core CPUs have four processing cores. These cores act as separate processors, but reside in a single chip. A quad-core CPU can process instructions using all four cores at the same time, but the computer's software must support multiprocessing in order to use the four cores effectively. Example: "Apple's Mac Pro workstations have quad-core CPUs."
