Answer:
Digital Certificate is the correct answer of this question.
Explanation:
Digital certificates are always for encryption and identification for transmitting public keys.The concept of digital certificate is a data structure used for linking an authenticated person to a public key. It is used to cryptographically attach public key rights to the organization that controls it.
<u>For example</u>:- Verisign, Entrust, etc.
- An appendix to an electronic document that is used for authentication purposes.
- A digital certificate's most frequent use is to confirm that an user sending a message is who he or she appears to be, and provide the recipient with the means to encode a response.
Overflow occurs when the magnitude of a number exceeds the range allowed by the size of the bit field. The sum of two identically-signed numbers may very well exceed the range of the bit field of those two numbers, and so in this case overflow is a possibility.
Answer:
11 bit slot will be needed
Explanation:
The number of prime numbers between 1 through 16
= 2, 3 , 5, 7, 11 and 13
hence we can say 6 stations are to use the shared channel
Given that all the stations are ready simultaneously
The number of bit slots that will be needed to handle the contention will be 11 bits :
slot 1 : 2, 3, 5 , 7, 11 , 13
slot 2 : 2,3, 5, 7
slot 3 : 2, 3
slot 4 : 2 . slot 5 : 3 . slot 6 : 5,7. slot 7 : 5 . slot 8 : 7. slot 9: 11,13.
slot 10 : 11. slot 11 : 13
