ITPEC IP April 2018 Question 10
ITPEC IP April 2018 — Question 10 of 100
Plug and Play automatically detects a newly connected peripheral and configures the device and its driver with little or no manual setup. The operating system identifies the hardware, assigns necessary resources, and loads or installs an appropriate driver.
Answer (a)
Why not others:
- later-installed software that extends an application is a plug-in or add-on
- supplying power through a connection describes bus power, such as USB power
- evaluating performance by timing a program describes benchmarking
Key rule: Plug and Play concerns automatic hardware recognition and configuration; it does not mean plug-ins, cable power, or performance testing.
