Answer:

To make sure that data sent from a device is just received by appropriate device we use "<u>Switch</u>"

Explanation:

Switch is the networking device. It is used to connect all the Local area networks in a computer network. The switch store the addresses of all computers over the network. Whenever data packet arrives to the switch, it just read the address of destination computer and just send it to appropriate device instead of all devices.

Hub is also used for this purpose, but it has no ability to read the address and send the packet to all devices over the network.

<em>So, we use Switch to send data to appropriate device.</em>

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.

Write a regular expression pattern that matches strings representing trains. A single letter stands for each kind of car in a tr

MAVERICK [17]

Answer:

See explaination

Explanation:

import re

def isValidTrain(train):

pattern = r'^E+(((P|PP|PPP|PPPP)D)*(BB)*)*C$'

if re.match(pattern, train):

return True

return False

def checkAndPrintTrain(train):

print("Train", train, "is valid:", isValidTrain(train))

checkAndPrintTrain("EC")

checkAndPrintTrain("EEEPPDBBPDBBBBC")

checkAndPrintTrain("EEBB")

checkAndPrintTrain("EBBBC")

checkAndPrintTrain("EEPPPPPPDBBC")

checkAndPrintTrain("EEPPBBC")

checkAndPrintTrain("EEBBDC")

Sample output

Train EC is valid: True

Train EEEPPDBBPDBBBBC is valid: True

Train EEBB is valid: False

Train EBBBC is valid: False

Train EEPPPPPPDBBC is valid: False

Train EEPPBBC is valid: False

Train EEBBDC is valid: False
