What do sensors detect in physical computing?

• Physical actions like button presses

• Software errors

• Network connections

• Data storage issues

Answer explanation

Sensors in physical computing detect physical actions like button presses, allowing devices to respond to user inputs. This is essential for interactive systems, making the first answer choice the correct one.

What is an example of a function in Microbit programming?

• display.show()

• print()

• input()

• output()

Answer explanation

The function 'display.show()' is specific to Microbit programming, used to display images or text on the Microbit's LED screen. The other options are general functions not specific to Microbit.
