A system that acts to minimize the change in concentration of a specific chemical species in solution against addition or depletion of this species. pH buffers: weak acids or weak bases in aqueous solution. The working range is given by pKa +/- 1. Metal ion buffers: a metal ion chelator eg. EDTA, partially saturated by the metal ion acts, as a buffer for the metal ion.
A temporary memory store which is used to compensate for differences in data transmission speed between, for example, a computer and a printer.
(2) A Storage device used to compensate for a difference between rates of transmission and receipt of data.
(1) A mechanically resilient protective coating that is applied over a fibre. Also referred to as Secondary Coating.
any substance or combination of substances that, when dissolved in water, produces a solution that resists a change in its hydrogen ion concentration on the addition of acid or base.

A zone of user-specified distance around a point, line or area. The generation of buffers to establish the proximity of features is one of the most common forms of GIS analysis. For example, it may be used to find all areas of industry less than 5km from a reservoir.

A memory cache that the Amiga uses to remember the contents of disks and hard drives to speed up access. To increase this you can use a PD utility such as PowerCache or put a line in your startup-sequence. By default the device DF0: is set to15 on boot up.Found on http://www.amigahistory.co.uk/b.html

pH buffer; buffer solution. A solution that can maintain its pH value with little change when acids or bases are added to it. Buffer solutions are usually prepared as mixtures of a weak acid with its own salt or mixtures of salts of weak acids. For example, a 50:50 mixture of 1 M acetic acid and 1 M sodium acetate buffers pH around 4.7.Found on http://antoine.frostburg.edu/chem/senese/101/glossary/b.shtml
Buffer is a solution designed to maintain a constant pH when small amounts of a strong acid or base are added. Buffers usually consist of a fairly weak acid and its salt with a strong base. Suitable concentrations are chosen so that the pH of the solution remains close to the pKa of the weak acid.Found on http://www.ktf-split.hr/periodni/en/abc/b.html
