ITPEC FE Morning October 2020 Question 12

Software that controls a peripheral device connected to the PC — the device driver translates the OS's generic requests into the commands one particular device understands.

Each printer, graphics card or network adapter comes with its own driver. The OS and applications call a standard interface, and the driver turns those calls into device-specific operations, so a new device only needs a new driver, not changes to the OS.

Answer (a)

Why not others:

• •(b) — software that installs applications is an installer
• •(c) — software that invades another PC and causes damage is malware, such as a worm or virus
• •(d) — recording keyboard or other operations and replaying them automatically is a macro or automation tool

Key rule: A driver sits between the OS and a specific piece of hardware; installers, malware and macro tools all act on software or users, not on devices.
