Answer:

Worm malware

Explanation:

The worm operates destructively as it replicates itself and keeps spreading within a computer or network. It takes advantage of software and security vulnerabilities.

Once a computer or network is infected, worms replicate themselves, therefore using up the computer and network resources. Among others, one of the major missions of worms is to create a backdoor into a network, to be able to enable the attacker to carry out a more devastating attack.

Since worms take advantage of weak security in the Operating system, it is very important to constantly update the security features of the Operating system. Users must be careful of the emails they open and attachments they download.

Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The
marin [14]

Answer:

Following are the program in the Python Programming Language

#set variable to input sentence to replace words

sen = input()

#split that sentence

sen = sen.split()

#set variable to input whole sentence

get = input()

#set the for loop to replace words

for i in range(0, len(sen), 2):

 #check condition when words of sen is in get

 if sen[i] in get:

   #then, replace words

   get = get.replace(sen[i], sen[i+1])

#print the whole string after replacing

print('\n',get)

Explanation:

<u>Following are the description of the program</u>.

  • Set a variable 'sen' that get a sentence for replacing the word.
  • Split that sentence by split() method and again store that sentence in the following variable.
  • Set a variable 'get' that gets the whole sentence from the user.
  • Set the for loop for replacing words then, set the if conditional statement that checks the condition that the variable 'sen' in the variable 'get' then replace the words.
  • Finally, print the whole sentence after the replacement.

Choose the correct sequence for classifier building from the following.
Alekssandra [29.7K]

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.

python Write a function that computes a future investment value at a given interest rate for a specified number of years. The fu
Svetlanka [38]

Answer:

def future_investment_value(investment, monthly_interest_rate, years):

  print("Years\tFuture Value")

  print("- - - - - - - - - - -")

  for i in range(1, years+1):

      future_value = investment * ((1 + monthly_interest_rate) ** (12 * i))

      print(i, "\t\t", format(future_value, ".2f"))

investment = float(input("Enter the invesment amount: "))

interest = float(input("Enter the annual interest rate: "))

year = int(input("Enter the year: "))

future_investment_value(investment, interest/1200, year)

Explanation:

Inside the function:

- In the for loop that iterates through the years, calculate the future value using the formula and print the results

Then:

- Ask the user for the investment, annual interest rate, and year

- Call the function with the given inputs

What conclusion can be made about the state of the program when the while loop terminates? Assume answer is a declared and initi
stellarik [79]

<u>Answer:</u>

<em>1. The loop will run unless the value of answer equals to Capital N.</em> The method equals is “case-sensitive” that is lower case letter and upper case letters are considered different. That “a” and “A” means the same to us, but for the method equals it is different and equals method will return false if the case is not matching.

<em>2. a (int)(Math.random() * (upper − lower) ) + lower </em>

Since we need to consider the lower limit value together to get the desired results we need to add the value of lower limit to the multiplied answer.

<em>3. b while(userGuess != secretNumber || userGuess >= lowerLimit && userGuess <= upperLimit)</em>

Here the program is required to check the while loop and exit when user guess the number or we can say the loop should continue until the user guess the number, so that is why we have taken <em>userGuess!=secretNumber. </em>Next the loop should be exited if it is not within the range or we can say that the loop should run only if the guessed number is within the upper and lower limit.<em> That is why we have opted for the condition userGues>=lowerlimit && userGuess<=upperlimit.</em> Why we have taken && as the operator is that, it’s a range of values so && operator best suit for this kind of logical condition.

Return 1 if ptr points to an element within the specified intArray, 0 otherwise.
Paladinen [302]

Answer:

int withinArray(int * intArray, int size, int * ptr) {

      if(ptr == NULL) // if ptr == NULL return 0

            return 0;

      // if end of intArr is reached

      if(size == 0)

          return 0; // element not found

  else  

          {

            if(*(intArray+size-1) == *(ptr)) // check if (size-1)th element is equal to ptr

                   return 1; // return 1

            return withinArray(intArray, size-1,ptr); // recursively call the function with size-1 elements

         }

}

Explanation:

Above is the completion of the program.
