Answer:

An operating system is a software that allows a user to run other applications on a computing device. The applications generally are not designed to interface directly with hardware, almost all of the applications are written to run on an operating system, in order to become independent of the hardware design.

The main function of an operating system are:

  • manage the hardware resources of a computer: central processing unit, memory, disk drives, and printers.
  • establish a user interface to facilitate the interaction human-computer.
  • execute and provide services for software applications.

Which of the following is not a mobile means of connecting devices to networks?
ElenaW [278]

Answer:

USB cables.

Explanation:

Think of what would happen if you started walking to a friend's house that is 3 houses away from yours. You have a cell and there are no others that you can see. Your friend calls you.

Could you hear what he says with a blue tooth earphone? Likely.

If you are connected by a wifi device. Again likely.

What about a broad band. That would be possible too.

So what about a USB cable. Now there's a problem. The cable would have to be at least 75 feet long (city plots are usually somewhere in the neighborhood of 25 feet wide). You would need an awfully long cable. And that's only 3 houses away.

Given a long integer representing a 10-digit phone number, output the area code, prefix, and line number using the format (800)
Alexxandr [17]

Answer:

See explanation!

Explanation:

Here we have a program written in C++ language. Each // symbol is a relative comment explaining the reason for each command line (and is not included during the program execution).

<em>The Program: </em>

#include <iostream>

<em>//c++ build in library</em>

using namespace std;

<em>//main code body starts here</em>

int main()

{

 <em> //declare variable to store phone numbers,its area code, prefix and line    number.</em>

  long pnumber;   <em>//declare long variable</em>

  int ac, prefix, lnumber;

 <em> //declare integer variables, where ac: Area Code and lnumber is the Line Number</em>

  cout<<"Enter a 10-digit Phone Number: "<<endl;

  <em>//cout command prints on screen the desired message</em>

  cin>>pnumber;

 <em> //cin command enables the user to interact with the programm and enter information manually</em>

 <em> //main body to obtain the desired output starts below</em>

<em>   //each 'division' is used to allocate the correct value at the correct </em>

<em>   //since prefix is used to get the desired output of ( )    -</em>

  ac = pnumber/10000000;

  prefix = (pnumber/10000)%1000;

  lnumber = pnumber%10000;

 <em> //main body ends here</em>

  cout<<"Based on your 10-digit number"<<endl;

  cout<<"below you have (AreaCode), Prefix, and - line number "<<endl;

  cout<<"("<<ac<<")"<<""<<prefix<<"-"<<lnumber<<endl;

 <em> //Prints on screen the desired output of the long 10 digit Number</em>

  return 0;<em> //ends program</em>

}

-------------------------------------------------------------------------------------------------------

<em>The Output Sample:</em>

Enter a 10-digit Phone Number:

8019004673

Based on your 10-digit number

below you have (Area Code), Prefix, and - line number

(801) 900-4673

<em>....Programm finished with exit code 0</em>
