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.
gamma radiation is both a type of nuclear radiation and electromagnetic radiation.
Radiation has both electric and magnetic fields and travels in waves. It comes from natural and man-made sources. The intensity of electromagnetic radiation varies from low energy to high energy. There are radio waves, microwaves, infrared rays, visible rays, ultraviolet rays, X-rays, and gamma rays.
Electromagnetic radiation consists of an electric field (E) of varying strength perpendicular to the direction of propagation of the radiation and a magnetic field (M) perpendicular to the electric field. Both fields move at the speed of light (c).
Electromagnetic radiation occurs when atoms absorb energy. The absorbed energy causes one or more electrons to change positions within the atom. Electromagnetic waves are generated when electrons return to their original positions.

Shamus Khan is a renowned sociologist with research interests on inequality and elites. He comes from an economically privileged immigrant family and attended St. Paul's school in Concord, New hampshire, where he graduated in 1996. Since he had a comfortable background and studied at that same institution, he was already familiar with the setting he would encounter during his reasearch in St. Paul's, which is stated in his book "Privilege
: The Making of an Adolescent Elite at St. Paul's School".
