persistence
1.
A property of a programming language where created objects and variables continue to exist and retain
their values between runs of the program.
2. 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.
