Counts per minute (abbreviated to cpm) is a measure of the detection rate of ionization events per minute. Counts are only manifested in the reading of the measuring instrument, and are not an absolute measure of the strength of the source of radiation. Whilst an instrument will display a rate of cpm, it does not have to detect counts for one ...
Actions per minute, abbreviated to APM, is a term used in video games, particularly real-time strategy and fighting games which refers to the total number of actions that a player can perform in a minute. Actions per minute are the number of actions (such as selecting units or issuing an order) completed within a minute of gameplay in real-time ...
Finger snapping. Snapping (or clicking) one's fingers is the act of creating a snapping or clicking sound with one's fingers. Primarily, this is done by building tension between the thumb and another ( middle, index, or ring) finger and then moving the other finger forcefully downward, so it hits the palm of the same hand at a high speed.
Click-through rate ( CTR) is the ratio of clicks on a specific link to the number of times a page, email, or advertisement is shown. It is commonly used to measure the success of an online advertising campaign for a particular website, as well as the effectiveness of email campaigns. [1] [2] Click-through rates for ad campaigns vary tremendously.
The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science, more specifically in the psychophysics of visual perception. A traditional term for "flicker fusion" is "persistence ...
The maximum delay required for two consecutive clicks to be interpreted as a double-click is not standardized. According to Microsoft's MSDN website, the default timing in Windows is 500 ms (half a second). [3] The double-click time is also used as a basis for other timed actions. The double-click timing delay can usually be configured by the user.
A minute of arc is π 10 800 of a radian . A second of arc, arcsecond (arcsec), or arc second, denoted by the symbol ″, [2] is 1 60 of an arcminute, 1 3600 of a degree, [1] 1 1 296 000 of a turn, and π 648 000 (about 1 206 264.8) of a radian. These units originated in Babylonian astronomy as ...
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.
