In the world of keystroke dynamics, what represents the amount of time you hold down in a
particular key?

A.
Dwell time

B.
Flight time

C.
Dynamic time

D.
Systems time

Explanation:
Keystroke dynamics looks at the way a person types at a keyboard. Specifically, keyboard dynamics
measures two distinct variables: “dwell time” which is the amount of time you hold down a
particular key and “flight time” which is the amount of time it takes a person to switch between
keys. Keyboard dynamics systems can measure one’s keyboard input up to 1000 times per second.
