A brute force is the type of attack that occurs when other users on a network are locked out because an intruder is trying to gain access by guessing a large number of password.
<h3>What is a
brute force?</h3>
A brute force attack refers to a situation where someone uses a trial-and-error to guess login info, encryption keys etc.
In conclusion, the brute force is the type of attack that occurs when other users on a network are locked out.

Answer:
Logical record, Physical record.
Explanation:
The logical record is structured and it is the unit of file I/O accessed by an application program as a single unit while the unit of storage transferred between the device controller and memory in a file I/O operation is the physical record which is often unstructured.
Answer:
When we know how many times a loop is going to occur when we make use of them for a loop. Like if we want to print a number 100 times, then we make use of them for a loop. However, if we only know the condition then we make use of the while loop.
Like while( sum<=100):
sum +=i
i=i+1
And this will add till sum <=100.
Hence, while requires us to know the number of times the loop will take place. And while requires a condition. On many occasions, both can be used. However, it must be understood that we increment the loop number at the end in case of the while loop and the beginning in case of a loop.

Answer:
Please check the attachment.
Explanation:
Firstly we need to draw the state diagram or the transition table. It clearly states through 4 bit even up counter that the next state of 0000 is 0010, and of 0010 is 0100 and so on. So we have the state diagram and the transition table, and thus answer for 1st and 2nd question.
Now through the Karnaugh map, we get the input circuit for D1, D2, D3, and D4. And these are mentioned in the attachment. Remember D outputs the same. which is the input. Thus, we have the answer for 3rd question. And then we draw the diagram, which can be found in the attachment. And this is the answer for the fourth question.
