A denial-of-service (or DoS) attack is where one single computer continuously sends information to a particular IP address in an attempt to overload the network, and take it down. It is called denial-of-service, because you are literally preventing other legitimate users from accessing the server. DoS attacks are not as commonly done professionally today, due to modern technological advances where these servers are able to cope with lots of junk packets from one user, and will often times just block their IP address if the packets are sent too frequently.

A distributed denial-of-service attack is where an IP address is overloaded from multiple users at the same time, often general users like you and I. The way this is accomplished is through botnets, which are simple non-malicious programs that are retrieved through downloading things on the internet, often things like torrents, and they are hard to remove due to them being non malicious. A botnet simply routes internet traffic from the user's computer to the victim's IP address, and due to the nature of a botnet being able to spread to multiple computers very quickly via the internet, DDoS'ing is a much more potentially devastating attack, and loads of junk packets coming from tons of different users compared to one user in a DoS attack is much more likely to take down a server or a network. Additionally, the victim server is unable to distinguish the difference between an attacker and a legitimate user, as the packets are not sent too frequently from each user as to not get IP blocked, but the attack rather relies on the fact that there could sometimes be hundreds of thousands of users all at once, attacking a single IP address.

6.4 Predicting Prices of Used Cars. The file ToyotaCorolla.csv contains data on used cars (Toyota Corolla) on sale during late s
Brums [2.3K]

Answer:

Compare the predictions in terms of the predictors that were used, the magnitude of the difference between the two predictions, and the advantages and disadvantages of the two methods.

Our predictions for the two models were very simmilar. A difference of $32.78 (less than 1% of the total price of the car) is statistically insignificant in this case. Our binned model returned a whole number while the full model returned a more “accurate” price, but ultimately it is a wash. Both models had comparable accuracy, but the full regression seemed to be better trained. If we wanted to use the binned model I would suggest creating smaller bin ranges to prevent underfitting the model. However, when considering the the overall accuracy range and the car sale market both models would be

Develop a C program that calculates the final score and the average score for a student from his/her (1)class participation, (2)
White raven [17]

Answer:

Following are the code to the given question:

#include<iostream>//defining header file

using namespace std;

int main()//defining main method

{

float clspat,test,asst,exam,practice,total,average;//defining floating variable

char name[100];//defining char variable to input value

cout<<"Enter Name of Student: ";//print message

cin>>name; //input value

cout<<"Enter scores in following scoring items between 0 and 100:"<<"\n";//print message

cout<<"Enter class participation score: ";//print message

cin>>clspat;//input value

cout<<"Enter test score: ";//print message

cin>>test;//input value

cout<<"Enter assignment score: ";//print message

cin>>asst;//input value

cout<<"Enter exam score: ";//print message

cin>>exam;//input value

cout<<"Enter practice score: ";//print message

cin>>practice;//input value

total=clspat+test+asst+exam+practice;//calculating total value

average=total/5;//calculating average value

cout<<endl<<"SCORE CARD OF "<<name<<"\n"<<"-----------------------"<<"\n";//print value with message

cout<<"Total score: "<<total<<"\n";//print message with value

cout<<"Average score: "<<average; //print message with value

}

Output:

please find the attached file.

Explanation:

In this code, the floating-point variable is declared, which is used for input value from the user-end and after input the floating-point value it uses the "total, average" variable to calculate its respective values and store its value with init, after storing the value into the variable it uses the print method to print its values.
