Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Platform as a Service (PaaS).

2. Infrastructure as a Service (IaaS).

3. Software as a Service (SaaS).

All of the following statements are true and correct because they are standard internet protocols;

I. Virtual appliances are becoming a very important standard cloud computing deployment object. This depicts the Platform as a Service (PaaS).

II. Cloud computing requires some standard protocols.

III. Cloud computing relies on a set of protocols needed to manage interprocess communications.

eduard

Answer:

Python Code

Explanation:

total = 0.0

change = 0.0

itemone = float(input("Enter the first price: "))

itemtwo = float(input("Enter the second price: "))

itemthree = float(input("Enter the third price: "))

total = itemone + itemtwo + itemthree

print("Total:", total)

cash = float(input("Cash given: "))

change = total - cash

print("Your change:", change)

WINSTONCH [101]

Answer:

The answer is "Option A"

Explanation:

In the OOPs programming language, the class and object concept is used, in which class is a collection of data members, and member function and object is known as real-time entity. In the class when the main method is created, so inside this method class object is created that's why the answer to this question is true.

Write only in C, not C++.

yawa3891 [41]

Answer:

#include <iostream>

using namespace std;

int main() {

int k;

double d;

string s;

cin >> k >> d >> s;

cout << s << " " << d << " " << k << "\n" << k << " " << d << " " << s; }

Explanation:

k is int type variable that stores integer values.

d is double type variable that stores real number.

s is string type variable that stores word.

cin statement is used to take input from user. cin takes an integer, a real number and a word from user. The user first enters an integer value, then a real number and then a small word as input.

cout statement is used to display the output on the screen. cout displays the value of k, d and s which entered by user.

First the values of k, d and s are displayed in reverse order. This means the word is displayed first, then the real number and then the integer separated again by EXACTLY one space from each other. " " used to represent a single space.

Then next line \n is used to produce a new line.

So in the next line values of k, d and s are displayed in original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.

The program along with the output is attached.

Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600 MHz. Computer B has a CPI of 2.5 and can be run at a

kirill115 [55]

Answer:

Check the explanation

Explanation:

CPI means Clock cycle per Instruction

given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M

Execution time is given by following Formula.

Execution Time(CPU time) = CPI*Instruction Count * clock time = $\frac{CPI*Instruction Count}{ClockRate}$

for system A CPU time is 1.3 * 100, 000 600 106

= 216.67 micro sec.

for system B CPU time is $=\frac{2.5*100,000}{750*10^6}$

= 333.33 micro sec

c) Since the system B is slower than system A, So the system A executes the given program in less time

Hence take CPU execution time of system B as CPU time of System A.

therefore

216.67 micro = = $\frac{2.5*Instruction}{750*10^6}$

Instructions = 216.67*750/2.5

= 65001

hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A
