The router can deliver packets directly over interfaces 0 and 1 or it can forward packets to Routers R2, R3, or R4. Describe wha
ra1l [238]

Answer:

Following are the solution to this question:

Explanation:

In point A:

It applies the AND operation with the subnet-mask that is  

=128.96.39.00001010 \ \ AND \ \ 255.255.255.10000000 \\\\= 128.96.39.0000000 \\\\= 128.96.39.0 \\\

This corresponds to a 128.96.39.0 subnet. This is why the router sent the packet to 0.

In point B:  

It applies the AND operation with the subnet-mask that is 255.255.255.128

= 128.96.40.00001100\  AND \ 255.255.255.10000000 \\\\ = 128.96.40.0000000\\\\= 128.96.40.0

This suits the 128.96.40.0 subnet. The router then sent R2 to the packet. The packet.

In point C:  

It  applies the AND operation with the subnet-mask that is 255.255.255.128

=128.96.40.10010111 \ AND \ 255.255.255.10000000 \\\\= 128.96.40.1000000\\\\= 128.96.40.128

It  applies the AND operation with the subnet-mask  that is 255.255.255.192

= 128.96.40.10010111 \ AND \ 255.255.255.11000000 \\\\= 128.96.40.1000000 \\\\= 128.96.40.128\\

All of the matches of its sublinks above.  

Its default R4 router was therefore sent to the router by router.

In point D:

It  applies the AND operation with the subnet-mask  that is 255.255.255.192

= 192.4.153.00010001 \ AND \ 255.255.255.11000000\\\\ = 192.4.153.0000000 \\\\= 192.4.153.0 \\\\

It matches the 192.4.153.0 subnet. It router has sent packet to R3 then.

In point E:

It  applies the AND operation with the subnet-mask  that is 255.255.255.128

= 192.4.153.01011010\  AND \ 255.255.255.10000000 \\\\= 192.4.153.0000000 \\\\= 192.4.153.0

There, neither of the subnet inputs correlate with the ip address with the same subnet mask.

It  applies the AND operation with the subnet-mask  that is 255.255.255.192

=192.4.153.01011010\ AND \ 255.255.255.11000000 \\\\ = 192.4.153.0100000 \\\\= 192.4.153.64

It does not correlate to the subnet entries for same subnet mask, and therefore neither of the entries matches their corresponding ip address entries.  

Mask of the subnet.  That packet would therefore be sent to the default R4 router by the router.

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>
