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.
The meaning of mesh topology is that it is a type of networking that is made up of the fact that all its nodes do work together to share data amongst each other.
<h3>What is meant by mesh topology?</h3>
Mesh topology is a kind of networking that is said to be where the full nodes do act in a form of a cooperation so that they can be able to share or distribute data among themselves.
Note that this topology was said to be first seen or developed in about an approximate of about 30+ years ago and it is one that is often used in military applications and now it is seen to be used in home automation, smart HVAC control, and others.
Hence, The meaning of mesh topology is that it is a type of networking that is made up of the fact that all its nodes do work together to share data amongst each other.

Answer: Federation
Explanation:
In multiple enterprises there are number of authentication processes to access resources and information so in order to avoid a large number of authentications we have a process called federation whereby all the authentication and authorization processes are passes from one system to the other within the enterprise.
Software as a Service cloud model is ideal for Rita’s business. SaaS are office solutions that allow Rita’s small business to work more efficiently and in a more organized way. Most SaaS applications are used for invoicing and accounting, sales, performance monitoring, and overall planning. SaaS applications can save Rita money.

Whoever manages SaaS’s IT infrastructure running the applications brings down fees for software and hardware maintenance. SaaS has generally been acknowledged to be safer than most on-premise software.
