You will create a simple client server program with a language of your choice (python is highly recommended) where a server is running and a client connects, sends a ping message, the server responds with a pong message or drops the packet.
You can have this program run on your machine or on the cse machines. Note that you will run two instances of your shell / IDE / whatever and they will communicate locally (though over the INET domain) - you can connect to your localhost (127.0.0.1 or make use of the gethostname() function in python).
Use UDP (SOCK_DGRAM) sockets for this assignment (parameter passed to socket()).
useful links:
https://docs.python.org/3/library/socket.html
https://docs.python.org/3/library/socket.html#example
details:
client.py
create a UDP socket (hostname and port are command line arguments or hard coded).
send 10 (probably in a loop) 'PING' message (hint: messages are bytes objects (Links to an external site.))
wait for the response back from the server for each with a timeout (see settimeout() (Links to an external site.))
if the server times out report that to the console, otherwise report the 'PONG' message recieved
server.py
create a UDP socket and bind it to the hostname of your machine and the same port as in the client (again either command line or hardcoded).
infinitely wait for a message from the client.
when recieve a 'PING' respond back with a 'PONG' 70% of the time and artificially "drop" the packet 30% of the time (just don't send anything back).
Server should report each ping message and each dropped packet to the console (just print it)
hint: for the dropping of packets, use random number generation (Links to an external site.)
You will submit 2 source code files (client.py and server.py), a README file that explains how to run your program as well as screenshots of your program running (they can be running on your own machine or the CSE machine). NOTE: your screenshot should include your name / EUID somewhere (you can print it at the beginning of your program or change the command prompt to your name, etc)
Example client output (Tautou is the hostname of my machine, 8008 is a random port i like to use - note you can hard code your hostname and port if you prefer):
λ python client.py Tautou 8008
1 : sent PING... received b'PONG'
2 : sent PING... Timed Out
3 : sent PING... Timed Out
4 : sent PING... received b'PONG'
5 : sent PING... received b'PONG'
6 : sent PING... Timed Out
7 : sent PING... received b'PONG'
8 : sent PING... received b'PONG'
9 : sent PING... received b'PONG'
10 : sent PING... received b'PONG'
example server output:
λ python server.py 8008
[server] : ready to accept data...
[client] : PING
[server] : packet dropped
[server] : packet dropped
[client] : PING
[client] : PING
[server] : packet dropped
[client] : PING
[client] : PING
[client] : PING
[client] : PING
python server.py 8000.
I can definitely help you with that! Here's a sample code in Python for a simple client-server program using UDP sockets:
client.py
import socket
import sys
SERVER_HOST = sys.argv[1]
SERVER_PORT = int(sys.argv[2])
PING_MESSAGE = b'PING'
# Create a UDP socket
client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
for i in range(1, 11):
# Send a ping message to the server
print(f'{i} : sent PING...')
client_socket.sendto(PING_MESSAGE, (SERVER_HOST, SERVER_PORT))
try:
# Wait for a pong message from the server
client_socket.settimeout(3.0)
response, server_address = client_socket.recvfrom(1024)
# If a pong message is received, print it
if response == b'PONG':
print(f'{i} : received {response}')
except socket.timeout:
# If the server times out, report it to the console
print(f'{i} : Timed Out')
# Close the connection
client_socket.close()
server.py
import socket
import sys
import random
SERVER_PORT = int(sys.argv[1])
PONG_MESSAGE = b'PONG'
# Create a UDP socket and bind it to the server address
server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
server_address = ('', SERVER_PORT)
server_socket.bind(server_address)
print('[server]: ready to accept data...')
while True:
# Wait for a ping message from the client
data, client_address = server_socket.recvfrom(1024)
if data == b'PING':
# Drop packet 30% of the time
drop_packet = random.random() < 0.3
# If packet is dropped, do not send a pong message
if drop_packet:
print('[server]: packet dropped')
else:
# Send a pong message to the client
server_socket.sendto(PONG_MESSAGE, client_address)
print('[client]: PING')
# Close the connection
server_socket.close()
To run the program, you can open two terminal windows and run the server.py file on one window and the client.py file on another window. In the client window, you will need to provide the hostname and port number for the server as command-line arguments. For example, to connect to a server running on localhost with port 8000:
python client.py localhost 8000
In the server window, you only need to provide the port number as a command-line argument:
python server.py 8000

which of the following types of storage would you recommend if someone needed a hard drive with fast data access and a small outline?a. Magnetic hard driveb. Solid-state hard drivec. Flash drived. Optical drive
If someone needs a hard drive with fast data access and a small outline, the type of storage that should be recommended is a Solid-state hard drive (SSD). The correct answer is B.
An SSD, also known as a solid-state drive, is a storage device that employs flash memory to store data. It is smaller in size and faster than a standard hard disk drive (HDD). It has a faster read/write speed than an HDD and consumes less energy than an HDD because it does not have any moving parts.
A magnetic hard drive has moving parts and is slower than an SSD. Optical drives, on the other hand, are used to read data from CDs, DVDs, and Blu-ray discs, and are not suitable for storage purposes. Flash drives are often used for data transfer and storage, but they have a lower storage capacity than an SSD.
Therefore, if someone needed a hard drive with fast data access and a small outline, the type of storage that would be recommended is a Solid-state hard drive (SSD).

You are working for an online gaming company. You have been asked to write some code to support
online card games, such as poker, gin rummy, other games. As a starting point, you have been asked to
write prototype code that does the following:
• Create a deck of cards
o There 10 card values, numbered 0 through 9, and there are four cards for each card
value
o You do not need to track suits (e.g., hearts, spades, etc.); for the purposes of this
assignment, all cards with the same card value are equivalent.
• Deal a set of hands to a set of players
o There are five cards per hand and four players per game
• Record counts of the multiples and singletons for the cards in each hand (four of a kind, three of
a kind, pairs, singletons, etc.)
• Store the state of the deck, hands, and hand counts in a set of arrays
o These will be used and updated over the course of games, so simply printing the state of
cards and hands at the start of the game is not sufficient
Any game played with playing cards is considered a card game. Poker, bridge, blackjack, solitaire, and go fish are a few popular card games.

Use Pointer1.cpp to explore basic pointer concepts (30 minutes in coding).Question: Consider the call to display2() in main(), what's wrong with the call?Coding (finish in 5min): Fix the problem you saw in the first question without changing display2().Take away: notice the difference of "&" and "*" and how to pass parametersCoding (finish in 15min):Create a new function named "display3," which looks like "void display3(int m, int* p)"In "display3," assign new values to "m" and "*p"Print out the values of "b" and "a" in in main()Call "display3" by passing in "b" and "aPtr"Print out the values of "b" and "a" in in main() again, after calling display3() in the previous stepTake away: parameter values can be changed "following" (de-referencing) pointers. This is one way to return results from a function (by defining parameter as references or pointers).Coding (finish in 5min)Please update function "display3"In "display3," after the code to update the value of "*p," print out "*p," "p" and "&p."Take away: pay attention to the values printed out:int a = 3, &p(a); // a is 3, p refers to acout << p; // shows the value referred to by p ==> 3cout << &p; // shows the address of the variable referred to by p, ==> &aCoding (finish in 5min): Back in main(), at the bottom, assign a new value to the storage that "aPtr" points to (hint: use the dereference operator) and output both "*aPtr" and "a" - what has happened?
In Pointer1.cpp, the call to display2() in main() is missing the parameter. It should be display2(aPtr).
In the new function "display3", we assign new values to "m" and "*p" using the dereference operator. Then we print out the values of "b" and "a" in main() before and after calling "display3". This demonstrates how parameter values can be changed following pointers, allowing us to return results from a function.
To update the function "display3", we add code to print out the value, pointer, and address of the variable "*p" after updating its value.
Finally, back in main(), we assign a new value to the storage that "aPtr" points to using the dereference operator. We output both "*aPtr" and "a" to see the result. This demonstrates how changing the value of the storage pointed to by a pointer can affect the value of the original variable.
