Buffer capacity falls to 33% of the maximum value at pH = pK a ± 1, to 10% at pH = pK a ± 1.5 and to 1% at pH = pK a ± 2. For this reason the most useful range is approximately p K a ± 1. When choosing a buffer for use at a specific pH, it should have a p K a value as close as possible to that pH.
A circular buffer can be implemented using a pointer and three integers: [4] buffer start in memory; buffer capacity (length) write to buffer index (end) read from buffer index (start) This image shows a partially full buffer with Length = 7: This image shows a full buffer with four elements (numbers 1 through 4) having been overwritten:
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes ...

A variation on z-buffering which results in more evenly distributed precision is called w-buffering (see below). At the start of a new scene, the z-buffer must be cleared to a defined value, usually 1.0, because this value is the upper limit (on a scale of 0 to 1) of depth, meaning that no object is present at this point through the viewing ...
added a section on buffer capacity; added simple and universal buffer mixtures; added four significant references; The applications section does not, at present, do the topic justice, I don't have the time to do this. See acid dissociation constant for some other applications, with references. Petergans 18:47, 27 August 2008 (UTC)
