Answer:
I am going to use the Python programming language to answer this. The source code is given below:
print("Enter your tweet here")
user_tweet = input()
decoded_tweet = user_tweet.replace('TTYL', 'talk to you later')
print("This is the decoded tweet: ")
print(decoded_tweet)
Explanation:
In the program the replace() module was used to replace 'TTYL' with 'talk to you later.'
Attached is the screenshot of the output.
Answer:
c.
Explanation:
I believe that in this scenario, the best option for this data would be a hash table using open addressing with 1,800 entries. Hash tables consume more memory than lists but it makes up for it with much faster response time speeds. This is because hash tables work on a key:value system therefore, the license plate can easily be grabbed from the database extremely quickly by just plugging in the plate number. Doing so will retrieve all of the saved information from that license plate. That is why hash tables have a constant time complexity of O(1)
Sending potentially sensitive information by email
Potentially sensitive information can be sent via Email only if the Email is encrypted
Explanation:
No doubt Email is an inexpensive efficient means of communicating quickly. But it is prone to hacking and it is not a secure mechanism. In order to add security ,the Email needs to be sent in an encrypted form. Banking and HIPAA regulations require the emails to be sent in encrypted form as it is a secure mechanism. Even if one has the consent from the client , the Email has to be in encrypted. Even if the Organization's e-mail system has appropriate firewalls and related infrastructure , the golden rule is to send encrypted format Emails.
