Answer:
CPU need 50% much faster
disk need 100% much faster
Explanation:
given data
workload spend time CPU = 60%
workload spend time I/O = 40%
achieve overall system speedup = 25%
to find out
How much faster does CPU need and How much faster does the disk need
solution
we apply here Amdahl’s law for the overall speed of a computer that is express as
S = 
.............................1
here f is fraction of work i.e 0.6 and S is overall speed i.e 100% + 25% = 125 % and k is speed up of component
so put all value in equation 1 we get
S =
1.25 = 
solve we get
k = 1.5
so we can say CPU need 50% much faster
and
when f = 0.4 and S = 125 %
put the value in equation 1
S =
1.25 = 
solve we get
k = 2
so here disk need 100% much faster
(D) Standard of living. Because, from this text you can tell that Leo is a wealthy person, and welthy people tend to get the best things, including fancy neighborhoods and Cars. So its most likely (D)
Answer:
There are additional security risks associated with using cloud computing over local data storage.
Explanation:
Cloud computing: The term "cloud computing" is described as a process through which an individual tends to access and store various programs and data over the internet rather than his or her computers' "hard drive". However, the term "cloud" here refers to a specific metaphor associated with the internet.
Types:
1. Software-as-a-service or SaaS.
2. Platform-as-a-service or PaaS.
3. Infrastructure-as-a-service or IaaS.
In the question above, the very first option is correct as all other options mentioned over here are incorrect because they aren't related to cloud computing.
Answer:
SURVEILLANCE-SPECIFIC DESIGN.
Explanation:
Defensible space offers a series of architectural guidelines that can be used in the design of new urban residential complexes to promote both the residential group’s territorial claim to its surroundings and its ability to conduct natural surveillance. The designs are: site interrelationship design, site design, street design and surveillance-specific design.
Surveillance-specific design can be used to increase general visibility by providing adequate lighting, by reducing or eliminating physical barriers to visibility, and by the visibility-promoting location of key areas (entrances, lobbies, elevator waiting areas, parking areas e.t.c.) so as to be directly visible from as many viewpoints as possible.
Since the data center designer requested additional lighting for the entrance to the data center as well as the removal of a object which is blocking security's view of the entrance, then it is an example of SURVEILLANCE-SPECIFIC DESIGN.
