Answer:
a) Speedup gain is 1.428 times.
b) Speedup gain is 1.81 times.
Explanation:
in order to calculate the speedup again of an application that has a 60 percent parallel component using Anklahls Law is speedup which state that:
Where S is the portion of the application that must be performed serially, and N is the number of processing cores.
(a) For N = 2 processing cores, and a 60%, then S = 40% or 0.4
Thus, the speedup is:
Speedup gain is 1.428 times.
(b) For N = 4 processing cores and a 60%, then S = 40% or 0.4
Thus, the speedup is:
Speedup gain is 1.81 times.
Answer
Use the drop-down menus to complete each sentence about the layers of the atmosphere.
If the Mesosphere did not exist, Earth might be destroyed by chunks of rock from space.
The Stratosphere is located 12 to 50 kilometers from Earth’s surface.
Both the Mesosphere and Troposphere get colder as altitude increases.
The ozone in the Stratosphere protects people from ultraviolet (UV) radiation.
The Themosphere has the highest temperature of any layer in Earth’s atmosphere.

Answer: Time slicing
Explanation:
Time slicing is one of the technique that basically implement the multitasking in the operating system. It basically generate the interrupt and at the each clock of the interrupt in the operating system basically regain control and then assign that particular system or processor to the another user.
Time slice are typically work in milliseconds. By using the multi users system, the time slice is the total amount of the processing time for the each user get assigned.
