Explanation:
function from S_1 to S_2 (functions have unique mapping
each element in S_1 has 2 elements to map to in S_2 and there are 3 elements in S_1
therefore number of functions = 2^3 = 8 (2 choices for each of 3 elements)
a) relations between S_1 and S_2 are subset of S_1 x S_2
there are 6 elements in S_1 x S_2 therefore relations would be 2^6 = 64
(no of subsets of set of n elements = 2^n)
b) By above explanation functions from S_2 to S_1 = 3^2 = 9
and relation from S_2 to S_2 = 2^4 = 16
Yes, a UDP packet header should contain both Sour Port # and Destination Port #.
<h3>Which fields are included in a UDP header?</h3>
The fields that one can see in a UDP header are:
<h3> Source port :</h3>
This is known to be the port of the device that is known to be sending the data. This field is one that a person can set to zero only if the destination computer do not require one to reply to the sender.
<h3> Destination port :</h3>
This is known to be the port of the device that is said to be getting or receiving the data.
Hence, to the answer above, my response is Yes, a UDP packet header should contain both Sour Port # and Destination Port #.

I’m not sure how to answer that
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.
The managers at Peter’s company have an Autocratic environment.
<u>Explanation:</u>
The managers who are autocratic in nature make decisions on their own. They will never get insights of their employees and they will not take the inputs of them in taking any decisions. This type of management is suitable in an organisation where there is an urgent need to taking decisions to any matter.
Managers who are autocratic in nature will make decisions without consulting anyone's advice. This type suits those organisations wherein there are very less number of employees. Here, the manager of Peter did not consulted peter in making decisions related to him, the environment is authoritarian or autocratic.
