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.

The full name for our year is 2020 A.D., which stands for Anno Domini or "in the year of our Lord". This began at the birth of Christ. So, when we say we're in the year 2020, what we're really saying is that it's been 2020 years since the birth of Christ.
Venus is unusual because it spins the opposite direction of Earth and most other planets. And its rotation is very slow. It takes about 243 Earth days to spin around just once. Because it's so close to the sun, a year goes by fast.
In the pillbug experiment, if the pillbugs in the experimental chamber would have moved to the side of the chamber with sand instead of cornstarch then the Pillbugs tend to prefer sand over cornstarch.
Pillbugs are categorised as terrestrial isopods and are in the crustacea family. The purpose of this experiment is to determine if pillbugs, often known as roly-polys, prefer light or darkness. They are cold-blooded, slow-moving organisms whose environs control their body temperatures.
The pill bugs are the controlled variable, and the behaviour of the pillbug is the dependent variable. The experimental group is housed in a moist environment with water and cornstarch, whereas the control group is in a dry environment with sand.
