ITPEC IP October 2020 Question 13
Which of the following is appropriate as a description concerning Plug and Play?
Explanation
The device driver is installed and set up automatically — Plug and Play lets the OS recognise a newly connected peripheral and configure it without manual settings.
When a device is connected, the OS identifies it, allocates the resources it needs and installs and configures the matching device driver, so the device is ready to use without the user setting anything by hand.
Answer (a)
Why not others:
- •(b) — describes a plug-in (add-in), software added later to extend an application's functions
- •(c) — describes bus power, such as a USB device powered through its cable
- •(d) — describes a benchmark test, which measures performance by timing a standard program
Key rule: Plug and Play is automatic recognition and driver setup of hardware; do not confuse it with plug-ins (software), bus power (electricity) or benchmarks (performance).
