ITPEC IP April 2024 Question 21
ITPEC IP April 2024 — Question 21 of 100
Function keys are keyboard keys to which an operating system or application assigns specific operations. They are usually labeled F1 through F12. Their action depends on context: for example, an application may use F1 for help, while other keys may refresh a view, open a command, or work with a modifier key to invoke another function.
Answer (a)
Why not others:
- (b) describes an on-screen or software keyboard, not physical function keys
- (c) confuses the ordinary meaning of a keyboard key with a cryptographic key used for encryption and decryption
- (d) describes a database key, such as a primary key, that uniquely identifies a row
Key rule: The word key has different meanings by context; a PC function key invokes a software-defined operation, whereas cryptographic and database keys are information rather than keyboard controls.
