Question

Eva is listening to music while she browses the Internet. Which type of operating system must she be using?

Answer 1

The info is a bit contradictory. Streaming music is real time. Doing more than one thing at a time is multi-tasking.

Answer 2

It depends on how she is listening to music. She could be listening to music on her MP3 player, stereo, at concert, via a music application on her computer or streaming from the internet. Its all a matter of perspective. For all of the possibilities I have listed above, her OS could be windows, iOS, linux etc. I think there are many OSes that can't do what you asked. But even windows or ios or even linux won't be able to do that without the required application.
