Which of the following protocols is used to unsure secure transmissions on port 443?A. HTTPSB. TelnetC. SFTPD. SHTTP

Answers

Answer 1
Answer:

Answer:

A. HTTPS

Explanation:

Default HTTP port is 80. This means that the server request is received on port 80. But default HTTP request is susceptible to interception. In order to prevent it, HTTP communication is secured using SSL encryption (HTTPS protocol). In this case the Url string begins with 'https://' which differentiates it from normal web request. The default port used for HTTPS service is 443 instead of 80.

PLEASE HELP!!!For this activity, you will create two designs for the same project. For example, you might choose to create a CD cover for your favorite band’s newest release, or you might want to design a menu for the local deli. No matter what you decide for your subject matter, the two designs must involve different media. One of these media will be an image-editing program, such as Inkscape. You will learn more about the basic tools available in Inkscape later in this lesson. The two designs should incorporate different techniques. For example, you might make one design abstract, while making the other more realistic. Be sure to save both of your designs. Scan or take a picture of the design that wasn’t created in an image-editing program. You will submit this item later in this lesson as your portfolio item.

Define a function below called average_strings. The function takes one argument: a list of strings. Complete the function so that it returns the average length of the strings in the list. An empty list should have an average of zero. Hint: don't forget that in order to get a string's length, you need the len function.

Answers

The required code written in python 3 which returns the average of the strings in a list goes thus :

def average_strings(string_list):

#initializeafunctionnamedaverage_stringwhichtakesinalistofstringasparameter

total_length = 0

#initializetotallengthofstringto0

if len(string_list)==0:

#checksofthe stringisempty

return 0

#ifstringisemptyreturn0

for word in string_list :

total_length += len(word)

#addthelength ofeachstringtothetotallengthofthe string.

return total_length / len(string_list)

#returntheaveragevalue

A sample run of the function is given here and the output attached.

string_list = ['dog', 'cat', 'mouse']

print(average_strings(string_list))

Answer:

def average_strings(lst):

   total = 0

   if len(lst) == 0:

       return 0

   for s in lst:

       total += len(s)

   return total / len(lst)

Explanation:

Create a function called average_strings that take one parameter, lst

Initialize a total to hold the length of the strings in lst

If the length of lst is 0, return 0

Otherwise create a for loop that iterates through the lst. Calculate the length of each string in lst and add it to total

When the loop is done, return the average, total length of the strings divided by length of the lst

A proper divisor of a positive integer $n$ is a positive integer $d < n$ such that $d$ divides $n$ evenly, or alternatively if $n$ is a multiple of $d$. For example, the proper divisors of 12 are 1, 2, 3, 4, and 6, but not 12. A positive integer $n$ is called double-perfect if the sum of its proper divisors equals $2n$. For example, 120 is double-perfect (and in fact is the smallest double-perfect number) because its proper divisors are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, and 60, and their sum is 240, which is twice 120. There is only one other 3-digit double-perfect number. Write a Python program to find it, and enter the number as your answer below.

Answers

Answer:

The program written in Python is as follows:

See Explanation section for line by line explanation

for n in range(100,1000):

     isum = 0

     for d in range(1,n):

           if n%d == 0:

                 isum += d

     if isum == n * 2:

           print(n)

Explanation:

The program only considers 3 digit numbers. hence the range of n is from 100 to 999

for n in range(100,1000):

This line initializes sum to 0

     isum = 0

This line is an iteration that stands as the divisor

     for d in range(1,n):

This line checks if a number, d can evenly divide n

           if n%d == 0:

If yes, the sum is updated

                 isum += d

This line checks if the current number n is a double-perfect number

     if isum == n * 2:

If yes, n is printed

           print(n)

When the program is run, the displayed output is 120 and 672
