MAC: A family of personal computers from Apple, introduced in 1984. It was the first computer to popularize the graphical user interface (GUI), which, along with its hardware architecture, has provided a measure of consistency and ease of use that is unmatched. The Macintosh family is the largest non-IBM compatible personal computer series in use in what is essentially a PC versus Mac world. The first Mac had only a floppy disk and 128K of memory. Its "high-rise" cabinet and built-in 9" monochrome screen were unique. Maintained for a number of years and streamlined in its Classic model, the high-rise machine has long since given way to more traditional cabinetry. The first Macs were powered by Motorola's 32-bit 680x0 family of CPUs. In 1994, Apple introduced the PowerMacs, the next generation of Macintoshes, which use the PowerPC CPU chip. PowerMacs run native PowerPC applications and emulate traditional Mac 680x0 applications. DOS and Windows applications can be run with Insignia Solution's SoftWindows.
Macros Focus: Focusing range that allows you to take close-up pictures. A setting that allows a camera to focus on objects which are very near. It is a feature found on some 35mm, APS, and digital cameras.
Marquee: The outline of dots created by the selection tool on an image when an operator is performing a task such as cropping, cutting, drawing a mask, etc.
Mask: A defined area used to limit the effect of image-editing operations to certain regions of the image. In an electronic imaging system, masks are drawn manually (with a stylus or mouse) or created automatically--keyed to specific density levels or hue, saturation and luminance values in the image. It is similar to photographic lith masking in an enlarger

Memory Card: A credit-card-sized memory module used as an additional disk or disk alternative in laptops and palmtops. Called IC cards, ROM cards and RAM cards, they use a variety of chip types, including RAM, ROM, EEPROM and flash memory. RAM cards used in this manner contain a battery to keep the cells charged. Note that when you add more memory in a laptop, the plug-in cards may also be called memory cards or RAM cards, but these are not substitutes for disk. They extend the computer's normal RAM memory and are typically contained on proprietary plug-in modules. The memory card that functions as a disk typically uses the PCMCIA architecture and requires special software that accompanies the computer.
Microdrive: Microdrive is a micro-miniature high-capacity rotating disk drive that is slightly larger (thicker) than CompactFlash card. Microdrive conforms to the CF+ II standard that builds upon the basic CF specification. CF+ II microdrives are available in capacities of 170 MB and 340 MB.
