Answer:
Check the explanation
Explanation:
To solve the above question.
The two valid classes are:
1. Patron_identity
2. Books
Class generalization can be between Books and Patrol_identity to create a new superclass for All The Books that this patron has ever checked out.
Two valid associations can be between:
1.Patron_identity and books
2.Books and library catalogue
To keep a desktop computer or a server powered up when the electricity goes off in addition to protection against power fluctuations, an <u>uninterruptible power supply (UPS)</u>, which contains a built-in battery, can be used.
<u>Explanation</u>:
An uninterruptible power supply (UPS) is a device that allows a computer or server powered up for a short time, when the electricity goes off. UPS device also provides uninterrupted service during power fluctuation.
A battery is inbuilt in the UPS and provides power for few minutes to the computer to shut down it in a proper manner.
UPS is available at affordable cost and can be maintained at low cost compared to generators.

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.
