Answer:
a) Yes
b) Yes
c) Yes
d) No
e) Yes
f) No
Explanation:
a) All single-bit errors are caught by Cyclic Redundancy Check (CRC) and it produces 100 % of error detection.
b) All double-bit errors for any reasonably long message are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
c) 5 isolated bit errors are not caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit since CRC may not be able to catch all even numbers of isolated bit errors so it is not even.
It produces nearly 100 % of error detection.
d) All even numbers of isolated bit errors may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
e) All burst errors with burst lengths less than or equal to 32 are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
f) A burst error with burst length greater than 32 may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit.
Cyclic Redundancy Check (CRC) does not detect the length of error burst which is greater than or equal to r bits.

A Design Basis Threat (DBT) is known to be a characteristics of any given or potential insider and also those of external adversaries, that may try to have or gain unauthorized removal or sabotage, against a physical protection system that was set up designed and evaluated.
<h3>What are Cybersecurity objectives?</h3>
Cybersecurity aims are:
- To protect computer system,
- To protect networks,
- To protect software programs from such cyber attacks.
Note that a lot of digital attacks are targeted at accessing, changing, or deleting sensitive information as well as others.

Answer:
class Foo:
def F(self, n):
if n == 1:
return 1
return self.F(n - 1) + 3 * n - 2
Explanation:
This should cover part a to this question. The thing I'm not sure on is they use the term "method" which in python technically means a class function...but then list one argument with the function call which makes me think it is possibly just supposed to be a regular function. Which would be the following snippet. It would depend on if you are using classes or not yet in your coding class.
def F(n):
if n == 1:
return 1
return F(n - 1) + 3 * n - 2
Play around with it and look into python "lists" and "for loops" for part c. Part b I'm not sure what kind of example they want since I'm not in that class. Good luck!
