ITPEC IP October 2020 — Question 13 of 100
Plug and Play automatically detects a newly connected peripheral and performs or assists with driver installation and configuration. The operating system identifies the device, allocates resources, and loads a suitable driver so manual hardware setup is minimized.
Answer (a)
Why not others:
- separately installed software that extends an application is a plug-in
- supplying power through a connection describes bus-powered hardware
- timing a standard program to evaluate performance describes benchmarking
Key rule: Plug and Play concerns automatic device recognition and configuration when hardware is connected.
