DDoS - Distributed Denial of Service
<u>Explanation:</u>
- In DDoS attack, the attack comes from various system to a particular one by making some internet traffic.
- This attack is initiated from various compromised devices, sometimes distributed globally through a botnet. It is different from other attacks such as (DoS) Denial of Service attacks, in which it utilizes an unique Internet-connected device ( single network connection) to stream a target with the malicious traffic.
- So in DDoS, multiple systems are involved in the attack and hence we can conclude that as the answer.
Answer:
b
Explanation:
First, we need to initialize the classifier.
Then, we are required to train the classifier.
The next step is to predict the target.
And finally, we need to evaluate the classifier model.
You will find different algorithms for solving the classification problem. Some of them are like decision tree classification etc.
However, you need to know how these classifier works. And its explained before:
You need to initialize the classifier at first.
All kinds of classifiers in the scikit-learn make use of the method fit(x,y) for fitting the model or the training for the given training set in level y.
The predict(x) returns the y which is the predicted label.And this is prediction.
For evaluating the classifier model- the score(x,y) gives back the certain score for a mentioned test data x as well as the test label y.

The Correct syntax for inserting an image as hyperlink is given in explanation section
Explanation:
To make an image act as a hyperlink, place the image element within the HTML anchor "<a></a>" element.
The syntax of inserting image hyperlink in XHTML is given below.
<a href = "link_that_can_be_accessible"><img src="source of image" alt="display name if image not shown in the browser" border="0"/></a>
for example lets insert image as hyperlink
<a href="ajax.html"><img src="logo.gif" alt="AJAX" border="0" /></a>
The default appearance is a blue border around the image. Specifying border="0" removes the border around the image.
if you want to insert image from another folder then the image hyperlink looks like this:
<a href="ajax.html"><img src="/images/html5/logo.gif" alt="AJAX" border="0" /></a>
If you want to insert image from another server then image hyper link looks like this:
<a href="ajax.html"><img src="https://www.myExample.com/images/html5/logo.gif" alt="AJAX" border="0" /></a>
