Answer: D

Explanation: A doesn't make sense, B doesn't either.

However you're left with C and D. In this case I can understand if you picked C, but I picked that and got the answer wrong.

D makes sense since data abstraction means to simplify the code to make it easy to read and point out details while removing other components.

A function allows one to understand the intention of the code by its name and thus it makes it easier to read.

Therefore, I suggest D.

Aleonysh [2.5K]

Answer: C. Live

Explanation:

A live acquisition is where data is retrieved from a digital device directly via its normal interface such as activating a computer and initiating executables. Doing so has a certain level of risk because data is highly likely to be modified by the operating system. The process becomes significantly more common likely with less available disk space to the point of completely impractical to image.

artcher [175]

Answer:

C++ code is explained below

Explanation:

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

// Variables to store inputs

string robot_name = "Nao";

string visitor_name;

int age, first_num, second_num;

// Constant variable initialisation for programmer name

const string programmer_name = "XXXXXXXX";

// Constant variable initialisation for assignment number

const string assignment_num = "123546";

// Constant variable initialisation for due date

const string due_date = "16 August, 2019";

// Displaying robot's name as script

cout << "Hello, welcome to Montgornery College!";

cout << "My name is " << robot_name << " . May I have your name?" << "\n\n";

// Taking visitor's name as input from the visitor

cin >> visitor_name;

// Displaying vistor's name as script

cout << "\n\nNice to have your with us today, " << visitor_name << "! ";

cout << "Let me impress you with a small game.";

cout << "Give me the age of an important person or a pet to you. ";

cout << "Please give me only a number!" << "\n\n";

// Taking human age as input from the visitor

cin >> age;

// Displaying human's age as script

cout << "\n\nYou have entered " << age << ". If this is for a person,";

cout << " the age can be expressed as " << age << " years or ";

// Computing months, days, hours, minutes and seconds from age input

double months = age*12;

double days = months*30;

double hours = days*24;

double minutes = hours*60;

double seconds = minutes*60;

// Computing dogs and fish age from human's age

double dogs_age = 7*age;

double gold_fish_age = 5*age;

// Displaying months, hours, minutes, hours and seconds as script

cout << months << " months or about " << days << " days or";

cout << " about " << fixed << setprecision(0) << hours << " hours or about " << minutes;

// Displaying dogs age and gold fish age as script

cout << " it is " << dogs_age << " years old in human age.";

cout << " If this is for a gold fish, it is " << gold_fish_age;

cout << " years old in human age" << "\n\n";

cout << "Let's play another game, " << visitor_name << "!";

cout << "Give me a whole number." << "\n\n";

// Taking first whole number from the visitor

cin >> first_num;

cout << "\nVery well. Give me another whole number." << "\n\n";

// Taking second whole number from the vistor

cin >> second_num;

// Computing sum and division for displaying in the script

double sum = first_num+second_num;

double division = first_num/second_num;

// Displaying sum and division script

cout << "\nUsing the operator '+' in C++,";

cout << " the result of " << first_num << " + " << second_num;

cout << " is " << sum << ". Using the operator '/', the result ";

cout << "of " << first_num << " / " << second_num << " is " << division;

cout << "; however, the result of " << first_num << ".0 /" << second_num;

cout << ".0 is about " << floatDivision << "." << "\n\n";

cout << "Do you like the games, " << visitor_name << "?";

cout << " If you do, you can learn more by taking our classes.";

cout << ". If you don't, I am sad, You should talk to our Chairman!" << "\n\n";

// Displaying Programmer Name, Assignment Number and due date to output screen

cout << "Programmer Name : " << programmer_name << endl;

Which two factors most influenced the growth of the Internet during the 1970s?
eduard

Answer:

The answer is "increase in the power of public universities and increased appreciation for a liberal arts education". DARPA and Russia had nothing to do with this. Yes, the computer hardware improvement led to a growth, but National Science Foundation funding in 1981, and hence this is also not an option. And electrical power supply had nothing to do with this. Hence, the above answer. as the concept of the internet is based on liberal arts of education, to impart practical and intellectual skillsets, and hence to grow the social responsibility among the citizens of the whole world. Also, the power of public universities had a big role to play definitely, and this was confirmed from Pentagon as well then when the question was raised, is this due to the risk of a nuclear attack.

Many people think that the main reason was the nuclear attack threat, but that was not an issue definitely. Actually this was the time of liberalization, and the power of the public universities was increased. Hence, they got the chance to share the information of various sorts with the people, and in the process internet started expanding.

Explanation:

The answer is self explanatory.
