Installing Antivirus and Using Firewall checks the function and background of site. If site found to be suspicious then it blocks the program from running on the computer.
Antivirus protect your computer from malware, that can steal your data. From the viruses that can destroy your files. Its for this reason its important to have antivirus on the system.
Antivirus works in two ways.
In a first way it scan the program files of the system or coming through internet. Then it compares with the prerecorded definition of virus. Present in the database.
If the match is found then it blocks the file and gives the warning message. If not then it give safe message.
In the another method, it simply scans and goes through the files. Here it checks for any suspicious behavior shown by the file. This way protects you.
If firewall is not present in the computer. Then it increases the risk of unauthorized access of private data. Data leaks and hacking of computer can happen.
Firewall filters the good network from bad network for you and tells the incoming traffic is good or bad for the computer.
Firewall scans for the malicious code coming with the packet. With its database , compare it and flags it if danger is spotted and prevents it from entering the computer.

The typical cost to the retailer is \$200$200dollar sign, 200 per repair, and the plan covers a maximum of 333 repairs. Let xxx be the number of repairs a randomly chosen customer uses under the protection plan, and let fff be the retailer's profit from one of these protection plans. Based on data from all of its customers, here are the probability distributions of xxx and fff:
An electronics retailer offers an optional protection plan. The expected total cost to the retailer for repairs is 66,600.
What is expected value theory?Expected value theory is a subfield of decision theory that examines the likelihood and anticipated outcomes of specific decisions. It is based on the idea that decisions are made based on the probabilities and expected outcomes of those outcomes.
Instead of focusing on the actual outcome of a decision, this theory emphasizes the expected outcome. It attempts to determine the expected value of a decision by first calculating the probability of various outcomes.
The total expected benefit or cost of a decision, taking into account all of the possible outcomes and their probabilities, is known as the expected value.
An illustration of expected value theory is this question.
The maximum number of repairs (333) is multiplied by the cost of repairs ($200 ) to get the expected value in this example.
As a result, the retailer anticipates paying a total of $200 (200 ×333) for repairs, or $66,600

what process involves placing one pdu inside of another pdu?
Answer: encapsulation
Explanation: When a message is placed inside of another message, this is known as encapsulation. On networks, encapsulation takes place when one protocol data unit is carried inside of the data field of the next lower protocol data unit.
When a message is placed inside of another message, this is known as encapsulation.
What is Encapsulation?Encapsulation is one of the fundamental concepts of object-oriented programming (OOP). Encapsulation, as it is defined, is the idea of combining data itself with methods that operate on it into a single entity, much like a class in Java.
This concept is widely used to conceal the internal representation or state of an entity.
The fundamental idea of this system is straightforward. For example, you might possess some characteristic that is concealed from view from the exterior of an item.
Encapsulation is a technique for preventing direct user access to some object components, preventing users from seeing the state values for all of an object's variables.
Therefore, When a message is placed inside of another message, this is known as encapsulation.

In this program, prompt the user to enter a vowel. If they keep typing something other than a vowel... keep prompting them until they finally enter a vowel. Once they finally enter a vowel, tell them how many times it took them to properly enter a vowel. Specifically:
Setup your program with comments included
Prompt the user to type in a vowel.
Create a count variable to keep track of guesses
While the letter they enter is NOT a vowel {upper or lower case), tell the user, "That is not a vowel" and prompt them again to enter a vowel.
After the while loop, if the user entered a vowel on their first attempt, output "You entered a vowel on your first try!" or else, output, "It took you [count] tries to enter a vowel...sad"
HINT: Using the lower() or upper() method might save you some typing in your while condition

In this program, you are going to create a turtle graphic program that will draw a circle that gradually increases in size, however many times the user specifies. Specifically:
Create your program, including comments
Import the turtle module and add the stop command at the end
In between, create a turtle and screen
Change the color of the screen, shape of the turtle and color of the turtle
Prompt the user using numinput for a number between 1 - 20
Using a for loop, repeat the number of times the user entered above (**NOTE - you will need to typecast this as an int() since their input will be a float()**)
Inside the loop, draw a circle (that gets filled in) that increases in size each time through the loop. **use a new method called circle(#), where the number represents the radius of the circle**
HINT - use the variable from the for loop multiplied by or added to another number to help create an increasing larger circle
Answer:
Explanation:

# Ask the user for the number of times they want the circle to increase in size
times = int(input("How many times do you want the circle to increase in size? "))

Is is known that a current of 0. 200 a flows through a resistor when a voltage of 5. 00 v is applied across it. What is the resistance of this resistor?.
The resistance of the resistor is 25 Ohms when the current of 0. 200 a flows through a resistor when a voltage of 5. 00 v is applied across it.
Calculating :The equations above are mathematical expressions of this relationship.
V = I x R
I = V / R
R = V / I
In this case, the voltage is 5.00 V and the current is 0.200 A. By rearranging Ohm's Law, we can calculate the resistance of the resistor as follows:
R = V/I
R = 5.00 V / 0.200 A
R = 25 Ohms
What does it mean to resist?The opposition a substance provides to the flow of electric current is known as resistance. The standard unit of resistance is the ohm, which is sometimes written as a word and sometimes symbolized by the uppercase Greek letter omega. It is represented by the capital letter R.
What is Ohm's law?Ohm's law is one of the most fundamental and significant laws governing electric circuits. Under all physical conditions and temperatures remaining constant, Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.

The IV is typically used as part of an encryption algorithm, where it is combined with a secret key to encrypt a message. The IV is unique for each encryption session, and must be unpredictable and non-repeating. A good IV should not be reused across multiple encryption sessions, and it should be kept secret from anyone who does not have access to the decryption key.
