Answer:
learning tool. i may be wrong
Explanation:
Option D is the answer because Digital Certificate is an entity that generates electronic and distributes them upon proving their identity sufficiently. In early days there was issues with people using the certificates that were not even issued by the organizations. Today it's a cryptographic technique which uses digital signatures and gives users a digital certificate that can be authenticated anytime online by any organization and is unique for every user having it.
Option A cannot be the answer because it has nothing to do with the identity of person but rather it is for specific fields.
Option B is not answer because it has no key and score matter to do with it.
Option C Web transactions has nothing to do with the certificates.
Answer:
The program is as follows:
word = input("Enter a word: ")
if word:
if len(word) <= 4:
word = word[::-1]
else:
word = word[0]+word[1]+word[-2]+word[-1]
print(word)
else:
print('empty!')
Explanation:
This gets input for word from the user
word = input("Enter a word: ")
If input is not empty
if word:
This checks if the length is less than or equal to 4 characters
if len(word) <= 4:
If yes, this reverses the word
word = word[::-1]
If otherwise,
else:
This gets the first, second, second to last two characters
word = word[0]+word[1]+word[-2]+word[-1]
Print the new string
print(word)
Print empty, if input is empty
<em>else:
</em>
<em> print('empty!')</em>
Answer:
Recommended is frame relay architecture with a local loop at each factory supporting the frame relay service connection to the network provider's POP
Explanation:
Frame Relay can be seen as WAN protocol that is said to often operate at both the physical and data layers link of the OSI reference model due to it high-performance and due to the fact that FRAME RELAY are as well use across Integrated Services Digital Network (ISDN) interfaces in which they are designed for cost-efficient data transmission in order to enable effective intermittent traffic between local area networks (LANs) and endpoints in wide area networks (WANs) which is why frame contains all the information necessary to route it to the correct destination.
Therefore type of BN and WAN architecture and WAN service i would recommend based on the above information is FRAME RELAY ARCHITECTURE with a local loop at each factory supporting the frame relay service connection to the network provider's POP.
