persistence

[pər′sis·təns]
(electronics)
A measure of the length of time that the screen of a cathode-ray tube remains luminescent after excitation is removed; ranges from 1 for short persistence to 7 for long persistence.
A faint luminosity displayed by certain gases for some time after the passage of an electric discharge.
(meteorology)
With respect to the long-term nature of the wind at a given location, the ratio of the magnitude of the mean wind vector to the average speed of the wind without regard to direction. Also known as constancy; steadiness.

persistence

(programming)
A property of a programming language where created objects and variables continue to exist and retain their values between runs of the program.

persistence

(hardware)
The length of time a phosphor dot on the screen of a cathode ray tube will remain illuminated after it has been energised by the electron beam. Long-persistence phosphors reduce flicker, but generate ghost-like images that linger on screen for a fraction of a second.

persistence

(1) In a CRT, the time a phosphor dot remains illuminated after being energized. Long-persistence phosphors reduce flicker, but generate ghost-like images that linger on screen for a fraction of a second.

(2) In object technology, the storage of an object on a permanent storage device such as a disk or SSD. See persistent data and persistent name.
