A protocol for asynchronous data communications that represents the evolution from x.25 and Frame Relay. It includes specific considerations for QoS and allows for different packet priority and size.

RAM is a type of computer storage whose contents can be accessed in any order. This is in contrast to sequential memory devices such as magnetic tapes, discs and drums, in which the mechanical movement of the storage medium forces the computer to access data in a fixed order. It is usually implied that RAM can be both written to and read from, in contrast to read-only memory or ROM.

Computers use RAM to hold the program code and data during execution. In the first electronic computers, RAM wa...

Abbreviation of Printer Control Language, the Page Description Language (PDL) developed by Hewlett Packard and used in many of their laser and ink-jet printers. PCL 5 and later versions support a scalable font technology called Intellifont.

Locate the binary, source, and manual page files for specified commands/files.

The opening of a lens that admits light. Except in very simple cameras, the Aperture can be varied in size by an adjustable  diaphragm, which regulates the amount of light passing through the lens. The relative Aperture is measured as the focal length of the lens divided by the diameter of the Aperture; this is expressed as an f-number: f/3, f/5, and so on.

Aperature has a dramatic effect on the Depth-of-field of the photograph.

The Rank nominated by Google with their PageRank system. Google assigns a "popularity" rating to each page in their index on a scale of 1-10 so what they consider to be a good page might start around the 4-6 ranking mark an excellent page might be 7-10.

PageRank relies on the uniquely democratic nature of the web by using its vast Link structure as an indicator of an individual page´s value. In essence, Google interprets a Link from page A to page B as a vote, by page A, for page B...
