Answer:

D. Sequence number

Explanation:

The sequence number facilitates the keeping track of many segments. This enables it to determine which segments out of many in which it should be in. The sequence number field is usually 32 bits.

Sequence numbers are used in transmitting data because of their importance. Since data is transmitted in packets, they can be lost and as such the receiver uses the sequence numbers to reorder them.

After you create an array variable, you still need to ____ memory space.
Svetllana [295]
This is a little tricky. I would say reserve. It would help to know what programming language and class this is for because a lot of times when you create an array variable the memory is put onto the stack and you as the programmer do not reserve memory space. Now on the other hand, if you are programming in C and you want to create an array variable and put it on the heap then you would reserve memory space on the heap.

Suppose Client A initiates a Telnet session with Server S. At about the same time, Client B also initiates a Telnet session with
poizon [28]

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?

  1. the segment sent from A to S.
  2. the segment sent from B to S.
  3. the segment sent from S to A.
  4. the segment sent from S to B.
  5. 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?
  6. how about if they are the same host?

Answers

                           Source Port Numbers               Destination Port Number

  1. A -> S                      1467                                               23
  2. B -> S                       1513                                               23
  3. S->A                         23                                                  1467
  4. S->B                         23                                                  1513
  5. 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
  6. no, a port number identify UNIVOCALLY a process.

Write an expression using membership operators that prints "Special number" if special_num is one of the special numbers stored
Mashcka [7]

Answer:

In python, the statement can be written as:

<em>if(special_num in special_list): print("Special Number") </em>

Explanation:

We need to create a list with the name 'special_list' with some values and then check whether special_num is in the list or not using the membership operator.

Membership operator in python: <em>in</em>

Let us do it step by step in python:

<em>special_list = ['1', '2', '3','4']      #</em>A list with the values 1, 2, 3 and 4

<em>special_num = input("Enter the number to be checked as special \t") </em>

<em>#</em>Taking the input from the user in the variable special_num.

<em>if(special_num </em><em>in</em><em> special_list): print("Special Number") </em>

#Using the membership operator <em>in </em>to check whether it exists in the list or not.

Please refer to the image attached for the execution of above program.

So, the answer is:

In python, the statement can be written as:

<em>if(special_num in special_list): print("Special Number") </em>
