Answer:

DoS attack

Explanation:

A Denial of Service attack involves the sending of maliciously formatted data packets to a server. The packet can be larger than the allowed IP size such that when it arrives at the server, the server cannot identify the headers in the data packet for it to process and extract data. The server can either freeze or crash, denying allowed users access to its resources and making it unavailable.

Which of the following code is correct? I: print("Programming is fun") print("Python") print("Computer Science") II: print("Prog
vfiekz [6]

Answer:

None of the options is correct.

Explanation:

One of the simplest statements that you can write in Python is a print statement, which causes a message to be displayed on the screen. For example, the following statement causes the message Python programming is fun! to be displayed:

print 'Python programming is fun!'

Notice that after the word print, the Python programming is fun! was written inside a set of single-quote marks. The quote marks are necessary, but they will not be displayed. They simply mark the beginning and the end of the text that we wish to display.

Here is an example of how you would type this print statement at the interpreter’s

prompt:

>>> print 'Python programming is fun!'

After typing the statement you press the Enter key and the Python interpreter executes the statement, as shown here:

>>> print 'Python programming is fun!'

Python programming is fun!

>>>

Thus, the correct way to write the codes in the question is:

print 'Programming is fun'

print 'Python'

print 'Computer Science'

The derived class is the sub-class and it is derived from its super class, as a matter of fact in Java programming language, all classes are derived from some other class. Objects are made from classes with their state (fields) and behavior (methods) since objects are made from classes, the objects of the super class will not be the same as that of the subclass.
