Answer: B) Vertical Partitioning
Explanation:
As, vertical partitioning is performed on Relation X, it is used for dividing the relation X vertically in columns and it involves creation of tables and columns.

Answer:
An answer to this question is given below in explanation section.
Explanation:
The given question is incomplete. First, we write the complete question that is:
Suppose Client A initiates a Telnet session with Server S. At about the same time, Client B also initiates a Telnet session with Server S. Run telnet in a terminal and capture the traffic on Wireshark. For example, open a telnet session using this command: "telnet cs537.cs.csusm.edu". What are the source and destination port numbers for the following items?
- the segment sent from A to S.
- the segment sent from B to S.
- the segment sent from S to A.
- the segment sent from S to B.
- if A and B are different hosts, is it possible that the source port number in the segments from A to S is the same as that from B to S?
- how about if they are the same host?
Answers
Source Port Numbers Destination Port Number
- A -> S 1467 23
- B -> S 1513 23
- S->A 23 1467
- S->B 23 1513
- Yes, it is that the source port number in the segement from A to S is the same as that from B to S. In short, there is no relationship between port numbers on different hosts
- no, a port number identify UNIVOCALLY a process.
