Answer:
The answer is "Option a, and c".
Explanation:
Following are the description of the Digital Signature choices:
- To change the physical transportation of paper or link files in the computerized messaging system, some processes should be identified and utilized in digital signatures, which enables documentation to be validated unforgivably.
- Using public-key cryptography, digital signatures, that's an exquisite system, that's why options a and b are correct.
- Digital signatures are not a central authority, that's why the option B is wrong.

Answer:
The function in Python is as follows:
def digitSum( n ):
if n == 0:
return 0
if n>0:
return (n % 10 + digitSum(int(n / 10)))
else:
return -1 * (abs(n) % 10 + digitSum(int(abs(n) / 10)))
Explanation:
This defines the method
def digitSum( n ):
This returns 0 if the number is 0
<em> if n == 0:
</em>
<em> return 0
</em>
If the number is greater than 0, this recursively sum up the digits
<em> if n>0:
</em>
<em> return (n % 10 + digitSum(int(n / 10)))
</em>
If the number is lesser than 0, this recursively sum up the absolute value of the digits (i.e. the positive equivalent). The result is then negated
<em> else:
</em>
<em> return -1 * (abs(n) % 10 + digitSum(int(abs(n) / 10)))</em>
Answer:
Parameters of primitive type are considered by Java methods to be local variables.
Explanation:
The parameters in JAVA are passed by value only. This means a parameter is considered to be local and a copy of the value is created used locally.
So if you change parameters of the primitive type so the value you change is local to the method. This implies that a copy of the parameter is made and the changes made on this copy will not affect the argument's value. In a nut shell, the parameters of primitive type are considered by Java methods to be local variables.
