manager, Memmaker, which can be run from a DOS-prompt (but not within Windows). Running a memory manager can free up conventional (the first 640K) memory for use by programs.

MIME

Multipurpose Internet Mail Extensions, a standard format that allows the attachment of graphics and other non-text files, such as programs, to text-based e-mail messages.

Moiré

Moiré is caused by the printing process of images in printed materials such as books or magazines. Moiré is caused by the resolution the original picture was scanned or digitized at in combination with the resolution the image was then printed. Descreening can often remove the moiré effect from an image.

Monitor

The visual output screen of the computer. It works with tiny clusters of tiny red, green and blue dots which are struck by a beam of electrons sweeping across the screen in a raster pattern which causes their phosphors to give off specific light which, in turn, reaches your eye as perceived color.

MPEG-1

Video compression standard for consumer applications, developed by the Motion Picture Experts Group (ISO 11172). Good resolution and speed, VHS quality. Normally requires hardware decompression (e.g. ELSAmotion). It is designed for resolutions of 352 x 288 with 25 frames per second (PAL), or 352 x 240 with 30 or 24 frames per second (NTSC or motion picture) and for common CD-ROM transfer rates. Approx. 70 minutes of video can be saved on one CD.

MPEG-2

Broadcasting quality standard, for example for full CCIR 601 quality or HDTV (high-resolution 16:9 television). Requires considerably higher transfer rates and memory capacities than MPEG-1 and is therefore not suitable for the consumer market.

MPEG-3

This is a relatively new standard that compresses the image or audio (or both) without loss of quality. While MPEG-3 decoders/players are becoming more common, encoders/editors are not widely available.

NTSC

National Television Standard Committee. The standard video format of North America (including the United States), Central America, and Japan.

OCR or Optical Character Recognition

The software will attempt to convert a scanned image of a document into editable text to be used in a word- processing program. If the software does not recognize a character shape, it will either make its best guess or will insert a null type character (differs program to program). Good OCR software can be quite expensive. Some OCR software is quite advanced & can convert a variety of fonts and page formats, including forms. There are several different TWAIN-compliant OCR software packages that are available as 3rd-party software, some even available from the Internet as shareware or freeware: Cuneiform, OmniPage, WOCAR, TextBridge and others. OCR relies heavily on the clarity of the document scanned. Documents printed on an inkjet or laser printer most easily converted with OCR. Documents that have been printed on a dot matrix printer or come are carbon duplicates may be difficult to OCR. Some OCR programs can only convert to ASCII, plain, or other forms of text, which usually will not retain format or fonts, found in the original. Most OCR programs are incapable of converting any item that was not scanned in LineArt mode (single bit, black and white).
