ITPEC IP April 2026 Question 19

Topic: Computer ComponentAlso asked in April 2019, November 2021 and April 2024

Which of the following is an appropriate description about the function keys of a PC?

a)They are the keys where specific functions are assigned for each application and OS.b)They display a keyboard shape on a screen and enable input processing with software.c)They have a security role and are keys for performing encryption and decryption.d)They are information to uniquely identify a specific row in a database.

Explanation

Keys whose functions are assigned by each application and the OS — the F1 to F12 row changes its meaning with the software in use.

Function keys are the F1 to F12 keys along the top of a PC keyboard. They have no fixed meaning of their own: the OS and each application assign operations to them. F1 commonly opens help, F5 reloads the page in a web browser, and F2 renames a file in the Windows file manager, so the same key does different things in different programs.

Answer (a)

Why not others:

•(b) — describes a software keyboard (on-screen keyboard), a keyboard drawn on the display and operated by touch or mouse
•(c) — describes a cryptographic key, the secret value used for encryption and decryption
•(d) — describes a primary key, the column or columns that identify each row of a database table

Key rule: "Key" has several meanings in IT: a key on a keyboard (an input device), a cryptographic key (a secret value) and a database key (identifying data); read which one the question means.
