n. the chemical formula for carbon dioxide, a heavy odorless gas (CO2) formed during respiration and by the combustion or decomposition of organic substances; it is absorbed from the air by plants in photosynthesis. The formula itself, pronounced out, is often used instead of the full name, especially with reference to fire extinguishers using this gas for fire suppression; as, a CO2 extinguisher.
Syn. -- carbon dioxide, carbonic acid gas. [ WordNet 1.5 +PJC ]

a device for suppressing fire, consisting of a steel cylinder containing compressed carbon dioxide, which may be released by pressing on a handle. The release of the gas is usually accomplished through a hose attached to a funnel-shaped vent which is directed at the base of the fire, and when released, part of the carbon dioxide is chilled sufficiently to solidify into a powder. The large quantity of inert carbon dioxide released on top of a small fire is usually sufficient to exinguish the flame by excluding oxygen, and the cooling effect also helps drive the temperature of the combustible material below that required to support compustion. It is used in situations where putting water on the fire might cause undesirable damage. [ PJC ]

a. (Computers) having dates fully and properly represented, and not susceptible to failure due to the year 2000 bug.
Syn. -- date compliant. [ PJC ]

n. (Computers) an error in the coding of certain computer programs in which the year portion of dates was represented by only two decimal digits, assuming that the first two digits are “19”. In such a program the the year 1975 is represented as “75”. This was a common practise in computer programming even into the 1990's, as many programmers failed to consider that their programs would be used after the year 1999. Thus, with such a program, a person born in 2000 would be considered as 101 years old in 2001; many different serious problems, as various as the programs, could be caused by such an error. In 1998 many programs with the year 2000 bug were still not corrected, and it is not clear how many programs will retain the bug when the year 2000 arrives. Tune in then.
Syn. -- millemium bug, Y2K bug, Y2K problem. [ PJC ]
