ITPEC IP October 2021 — Question 21 of 100
Function keys are keyboard keys to which an operating system or application assigns particular operations. The actions of keys such as F1 through F12 can vary with the active software; for example, F1 commonly opens help.
Answer (a)
Why not others:
- an on-screen keyboard is software that displays a keyboard-shaped input interface
- cryptographic keys are data used by encryption algorithms, not function keys on a keyboard
- information that uniquely identifies a database row is a primary key
Key rule: A function key triggers a software-defined command, and its meaning can depend on the OS or application context.
