The best answer to this question should be (A)
Cloud Computing.
In general, cloud computing is the term used for the delivery
of hosted services over the internet. We can also simply put cloud computing as
the delivery of computing services like storage, servers, databases, software
and more over the internet.
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
The two characteristics of scalable network are such that it
can easily grow in size without causing any impact to the current users. This means,
increase in network capacity and technical capability will not have any detrimental
effects to the users. Another characteristic
of this network is that it can work perfectly with modular devices provided
they support expansion process.
Answer:
C++.
Explanation:
<em>Code snippet.</em>
#include <map>
#include <iterator>
cin<<N;
cout<<endl;
/////////////////////////////////////////////////
map<string, string> contacts;
string name, number;
for (int i = 0; i < N; i++) {
cin<<name;
cin<<number;
cout<<endl;
contacts.insert(pair<string, string> (name, number));
}
/////////////////////////////////////////////////////////////////////
map<string, string>::iterator it = contacts.begin();
while (it != contacts.end()) {
name= it->first;
number = it->second;
cout<<word<<" : "<< count<<endl;
it++;
}

I have used a C++ data structure or collection called Maps for the solution to the question.
Maps is part of STL in C++. It stores key value pairs as an element. And is perfect for the task at hand.
Answer:
A. <em>Encoding Process </em>
Explanation:
Memory is an <em>encoding process </em>that includes the organization and shaping of information by processing, storage, and retrieval of information.
There are two types of memory in computing, <em>RAM </em>and <em>ROM</em>. <em>RAM </em>stands for <em>Random Access Memory</em>. It I the core memory of the computer and it is especially faster regarding reading and writing process. As an analogy, RAM memory is like the “<em>Short-term</em>” memory of the computer. <em>ROM </em>stands for <em>Read-Only Memory</em>, this is the type of memory in charge of permanently storing data in the computer. It contains the necessary information to run the computer. As an analogy, <em>ROM </em>memory is like the “<em>long-term</em>” memory of the computer.
