ITPEC IP October 2023 — Question 12 of 100
A device driver enables the operating system and application software to communicate with a specific peripheral. It translates general input/output requests into commands the device understands and handles device-specific behavior, interrupts, and data transfer. Applications normally access the peripheral through operating-system interfaces backed by the driver.
Answer (b)
Why not others:
- (a) Compiler translates source code into executable or intermediate code
- (c) Plug and play automatically detects and configures compatible hardware, but the device still needs a driver
- (d) Hot plug allows a device to be connected or removed while the system is running
Key rule: The driver provides operational communication with hardware; plug and play and hot plug describe how hardware is detected or connected.
