Answer:polling and interrupt
Explanation: polling is a protocol in which the CPU constantly checked if a device request an important attention based on a request. The polling process unit constantly scans the device. Example of polling is when a parallel printer port is pulled to check whether it is ready for another character which involves examining as little as one bit of a byte.
interrupt is a mechanism whereby a device notifies a CPU that it requires a response based on a request. The CPU gets an interrupt signal via an interrupt request line allowing the CPU to spot it's current process and give priority to the interrupt request at that point in time. Example of interrupt is pressing a key on a keyboard which in turn triggers a specific interrupt handler.
Answer:
non-participant observation research method
Explanation:
In non-participant observation studies, Greg is not part of the group being studied. He decides in advance precisely what kind of behaviour is relevant to the study and can be realistically and ethically observed. He observes the way students talk to each other. He makes notes on the words used, the atmosphere of the school and the way the students present themselves to each other.The observation can be carried out in a few different ways. Observation does not only include noting what happened or was said but also the fact that a specific behaviour did not occur at the time of observation.

Everything a speaker says is filtered through a listener's
"Frame of reference".
Frame of reference is an intricate arrangement of
suppositions and states of mind which we use to channel observations to make
meaning. The frame can incorporate convictions, compositions, inclinations,
qualities, culture and different manners by which we predisposition our
comprehension and judgment. Like we are wearing pink glasses and normally trust
that the world has a pink shade, and subsequently that others will see it
similarly.
