Answer:
def analyze_text(sentence):
count = 0
e_count = 0
for s in sentence:
s = s.lower()
if s.isalpha():
count += 1
if s == "e":
e_count += 1
return "The text contains " + str(count) + " alphabetic characters, of which " + str(e_count) + " (" + str(e_count*100/count) + "%) are ‘e’."
Explanation:
Create a function called analyze_text takes a string, sentence
Initialize the count and e_count variables as 0
Create a for loop that iterates through the sentence
Inside the loop, convert all letters to lowercase using lower() function. Check each character. If a character is a letter, increment the count by 1. If a character is "e", increment the e_count by 1.
Return the count and e_count in required format
Answer:
a. Telnet transmissions are not encrypted.
Explanation:
Indeed, since <em>Telnet transmissions are not encrypted,</em> all the information sent, and even the characters typed in the telnet console are sent in clear text.
This is a security issue, since any other device in the same network will receive a copy of the information (packets) sent. For default, all the devices, except for the server expecting to receive the information, will discard the packets. However it is easy to actively <em>listen </em>and keep those packets, wich will contain the information in plain text and human readable.
