SDRAM
A generic name for various kinds of dynamic random access memory: DRAM that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM is rated in MHz rather than in nanoseconds (ns). This makes it easier to compare the bus speed and the RAM chip speed. You can convert the RAM clock speed to nanoseconds by dividing the chip speed into 1 billion ns (which is on...

GIF
A compressed graphic format suited for flat color images (illustrations) and drawings. It compresses images by referencing areas of the same colour thus it is less suitable then JPEG for photographic images (where there are colour gradients)

whereis
Locate the binary, source, and manual page files for specified commands/files. The supplied filenames are first stripped of leading pathname components and any (single) trailing extension of the form .ext (for example, .c). Prefixes of s. resulting from use of source code control are also dealt with. whereis then attempts to locate the desired program in a list of standard Linux directories (e.g., /bin, /etc, /usr/bin, /usr/local/bin/, etc.).

Aperture
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. |

XDe
The PawPrint XDe allows web site proprietors to pick and choose from various components that all work from a common database. Each module builds upon the others to provide additional functionality. These intelligent modules can even detect their peers and may offer additional functionality depending on what other modules are present.
The entire system can be customized through CSS and centralized site options (another XDe module) but implementation times are very short because of the cross pl... |
