Glossary 765
SOJ
Acronym for small outline package J-lead, a small-dimension, plastic, rectangular
surface mount chip package with j-shaped pins on its two long sides.
SRAM
Abbreviation for static random-access memory. Because SRAM chips do not
require continual refreshing, they are substantially faster than DRAM chips.
state
Refers to the condition of an object that can have more than one condition.
For example, an object may be in the "not ready" state.
status
Refers to the health or functioning of an object. For example, a temperature probe
can have the status normal if the probe is measuring acceptable temperatures.
When the probe begins reading temperatures that exceed limits set by the user,
it reports a critical status.
SVGA
Abbreviation for super video graphics array. VGA and SVGA are video standards
for video adapters with greater resolution and color display capabilities than
previous standards.
To display a program at a specific resolution, you must install the appropriate
video drivers and your monitor must support the resolution. Similarly, the number
of colors that a program can display depends on the capabilities of the monitor,
the video driver, and the amount of video memory installed in the computer.
switch
On a computer system board, switches control various circuits or functions in
your computer system. These switches are known as
DIP switches; they are
normally packaged in groups of two or more switches in a plastic case.
Two common DIP switches are used on system boards:
slide switches and rocker
switches. The names of the switches are based on how the settings (on and off) of
the switches are changed.
syntax
The rules that dictate how you must type a command or instruction so that the
computer understands it. A variable’s syntax indicates its data type.
