6. (Technology) in research, an object or subject used in an
experimental procedure, which is treated identically to
the primary subject of the experiment, except for the
omission of the specific treatment or conditions whose
effect is being investigated. If the control is a group of
living organisms, as is common in medical research, it is
called the

{control group}.

Note: For most experimental procedures, the results are not
considered valid and reliable unless a proper control
experiment is performed. There are various types of
control used in experimental science, and often several
groups of subjects serve as controls, being subjected
to different variations of the experimental procedure,
or controlling for several variables being tested. When
the effects caused by an experimental treatment are not
consistent and obvious, statistical analysis of the
results is typically used to determine if there are any
significant differences between the effects of
different experimental conditions.

7. (Technology) the part of an experimental procedure in
which the controls[6] are subjected to the experimental

8. the group of technical specialists exercising control by

(Or "ctrl", "^") One (or a pair) of {modifier
keys} found on all modern {keyboards}. If the control key is
held down while pressing and releasing certain other keys then
a "{control character}" is generated, e.g. holding control and
hitting "A" generates control-A ({ASCII} code 1). The ASCII
code for the control character is generally 64 less than that
for the unmodified character.

The control key does not generate any character on its own but
most modern keyboards and {operating systems} allow a program
to tell whether each of the individual keys on the keyboard
(including modifier keys) is pressed at any time.

Control characters mostly have some kind of "non-printing"
effect on the output such as ringing the bell (Control-G) or
advancing to the next line (Control-J). Most have alternative
names suggesting these functions (Bell, Line Feed, etc.).
