Answer:
QoS
Explanation:
We could use a blacklisting or a MAC filtering to remove from the network, and in this way, we're going to get a high portion of bandwidth, but other must work too, and the whitelisting have almost the same function, but QoS Quality of service is specifically for these cases where we need high bandwidth for a video conference, we can make this with some tools or techniques like jitter buffer and traffic shaping.
 
        
             
        
        
        
Answer:
ofstream asia("asiasales2009.txt");  //It is used to open asiasales2009.txt files with the asia objects.
ofstream europe("europesales2009.txt");  //It is used to open  europesales2009.txt files with the europe objects.
ofstream africa("africasales2009.txt");
//It is used to open africasales2009.txt files with the africa objects.
ofstream latin("latinamericasales2009.txt");//It is used to open latinamericasales2009.txt files with the latin objects.
Explanation:
- The above code is written in the c++ language which is used to open the specified files with the specified objects by the help of ofstream class as described in the question-statements.
 - The ofstream is used to open the file in the c++ programing language, so when a user wants to use the ofstream to open the file in written mode, then he needs to follow the below syntax--
 
               ofstream object("file_name_with_extension");
 
        
             
        
        
        
Answer:
a DoS attack occurred
Explanation:
According to my research on information technology and cybersecurity, I can say that based on the information provided within the question he can conclude that a DoS attack occurred. This (denial-of-service) attack is when an individual sends a large amount of network authentication requests with an invalid return address and overloads a server until it crashes. Which is why the company website says "page not found". All of these requests are usually from a single computer, which is also why they all originated from the same IP in this situation.

<u>Explanation:</u>
ASCII, abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication.  Basically, ASCII value is the something which computers understand .
C program that asks the user to enter a single character and then outputs the ASCII number of that character :
#include <stdio.h>
#include <string.h>
int main()  
{  
    char Str[10];
    int i,length;
    printf("Enter the String: ");
    scanf("%s", Str);
    if(strlen(Str) == 1){
        printf(" %c ASCII value is %d",Str[0],Str[0]);
    }
    else{
        printf(" Please enter only single character!! ");
    }
    return 0;  
}
