Answer:
Python file with appropriate comments given below
Explanation:
#Take the input file name
filename=input('Enter the input file name: ')
#Open the input file
inputFile = open(filename,"r+")
#Define the dictionary.
list={}
#Read and split the file using for loop
for word in inputFile.read().split():
#Check the word to be or not in file.
if word not in list:
list[word] = 1
#increment by 1
else:
list[word] += 1
#Close the file.
inputFile.close();
#print a line
print();
#The word are sorted as per their ASCII value.
fori in sorted(list):
#print the unique words and their
#frequencies in alphabetical order.
print("{0} {1} ".format(i, list[i]));
The correct answers are A. For extending the learning experience for students. C. So students can use the Slides for review and can go to additional resources outside of the presentation. D. To make the presentation more graphically appealing
Explanation:
The use of hyperlink objects in presentations means objects such as images, texts, or icons are associated with links or websites students can easily access by clicking on the specific image or element. This might be used in educational contexts to allow students to have a complete learning experience by providing alternative and external sources outside the presentation. For example, if the topic is space hyperlinks to NASA website can be included. This means, hyperlink objects extend learning experiences and provide additional resources (Option A and D).
Besides this, this resource can make a presentation more appealing as links to images, videos, and other visually interesting resources can be included (Option D). However, it also breaks the linearity of the presentation as students will need to move to other websites as they go through the presentation.

Explanation:
Playfair cipher invented in 1854 by Charles Wheatstone was the first practical digraph substitution cipher. Lord Playfair promoted the use of the cipher, therefore it was named after him. Playfair cipher encrypts pairs of letters (digraphs) making it hard to break. Frequency analysis can still be undertaken but requires much more cipher text in order to work. It requires no additional equipment to operate and is very fast therefore it is to protect information during war. It was used by British forces in the Second Boer War and in World War I and during World War II by the Australians.
When the PT-109 American patrol boat, under the command of Lieutenant John F. Kennedy, was sunk by a Japanese destroyer, a message was received at an Australian wireless station in the morning of the 2 of August 1943 in Playfair code:

upfront price, but dependent on how long you use it you will save money, also the power it provides per square inch is low but that will be solved with time.
