Well Formatted Question:

The _______ of the operating system enables users to communicate with the computer system.  

a) modem

b) window

c) network adapter card

d) user interface

Answer:

(d) user interface.

Explanation:

A user interface acts as a middleman between the user of a computer and the operating system of that computer. With the user interface, a user can easily communicate with the computer system including the applications running on it.

The user interface can either be text-based or graphics-based.

With text-based user interface, the user enters commands (using keyboards) in form of texts basically on the command line and then the operating system executes these commands.

With the graphical user interface, users interact with the computer using graphics-like control items such as buttons and menus to give instructions to the computer.

sleet_krkn [62]

Answer:

#include <iostream>

#include <stack>

#include <queue>

#include <string>

int main()

{

   while ( true )

   {

       std::string letters;

       std::cout << "Please enter a word (Enter - exit): ";

       std::getline( std::cin, letters );

       if ( letters.empty() ) break;

       std::stack<char>

           s( std::stack<char>::container_type( letters.begin(), letters.end() ) );

       std::queue<char>

           q( std::queue<char>::container_type( letters.begin(), letters.end() ) );

       while ( !s.empty() && s.top() == q.front() )

       {

           s.pop();

           q.pop();

       }

if ( s.empty() ) std::cout << "The word is a palindrome" << std::endl;

       else std::cout << "The word is not a palindrome" << std::endl;

   }

   return 0;

}

Explanation:

A <em>stack</em> is used to replicate a stack data structure in C++  while <em>Queue </em>container is a replica of the queue data structure in C++, Unlike stack, in the queue container, there are two ends, i.e. front, and back.

In the code above to be able to use used stack and queue, we included the headers #include <stack> and#include <queue>.

What field in a TCP segment is used to determine if an arriving data unit exactly matches the data unit sent by the source?
Rina8888 [55]

Answer:

a. Checksum

Explanation:

Based on the information provided within the question it can be said that the field that represents this information is called the Checksum. Like mentioned in the question this refers to a value that represents the amount of bits in a certain transmission message. This is done in order to make sure that the amount of bits that were sent match the amount that were received in order to make sure that no data was lost in transit that would cause high-level errors.

The area of a square is stored in a double variable named area. Write an expression whose value is length of the diagonal of the
melisa1 [442]

Answer:

sqrt(area)

Explanation:

  • Here sqrt is a short form of square root.
  • area is a variable name having he area of square.
  • When the function is called, it will give the square root of the value stored in variable area.

As we have to find the length of the diagonal, we must knew that as all sides of the square are same in length so are the diagonals. This means that each of the four sides of the square and it diagonals are equal in length.

So a square has: length=breadth=diagonal

As  Area= length*breadth

√area = length           (as length = diagonal length)

So     √area = diagonal length
