Students have asked these similar questions
the database for a professional hockey league in Canada that contains
the following relations:
teams(name, id, budget, home_venue_id)
players(name, position, id, salary, team_id)
⚫ venues(name, city, capacity, id)
games(home_team_id, away_team_id, venue_id, winner_id, date, start-time, id, overtime)
tickets(game_id, seat number, price)
Create an Entity-Relationship (E-R) model for the hockey league. Draw your model.
Your diagram should follow the conventions discussed in lecture. In the diagram, identify all
primary keys and mapping cardinalities.
Note: You may use software such as draw.io, PowerPoint, etc. to draw your diagram or you
may draw it by hand and take a clear photo or scan to insert into your submission.

It is a substitution cipher where each letter in the plaintext is shifted a certain number of places down the alphabet. For example, with a right shift of 3, 'A' would be replaced by 'D', 'B' would become 'E', and so on. The alphabet "wraps around," so with a shift of 3, 'X' would become 'A'. Your task is to implement this logic. 1. Develop a set of functions to encrypt a string using a Caesar cipher. 2. Develop a set of functions to decrypt a string using a Caesar cipher. 3. Develop a set of functions to help solve (break) a Caesar cipher by showing all possible shifts.4.

You are using a web browser to load a webpage. Let’s assume the size of the webpage is negligible. The access link rate of the webserver is 1 Gigabits per second. The IP address for the associated URL is not cached in your local host, so a DNS lookup is necessary to obtain the IP address. Suppose that n DNS servers are visited before your host receives the IP address from DNS; the successive visits incur an RTT of RTT1, . . . , RTTn. Let RTT0 denote the RTT between the local host and the webserver containing the webpage. Now answer the following: 1) Ignore all types of delays at the client and the servers.

- In a client-server file distribution paradigm, let’s assume the server has an upload rate of 25 Mbps. Each client’s download rate is 3 Mbps. Now consider multiple scenarios where the number of clients is 50, 200, and 1000. For each of these scenarios, consider 2 possible upload rates of each client: 200 Kbps, and 1Mbps. For these 6 combinations of the number of clients and the client-upload rate, what are the minimum distribution times for a file of size 30 Gigabit? Now, if the same file needs to be distributed in a P2P paradigm, what will be the 6 minimum distribution times? Show all calculations and provide detailed explanations.

The functionality provided by these programs will be similar to the functionality provided by standard ping programs available in modern operating systems. However, these programs will use a simpler protocol, UDP, rather than the standard Internet Control 1Message Protocol (ICMP) to communicate with each other. The ping protocol allows a client machine to send a packet of data to a remote machine, and have the remote machine return the data back to the client unchanged (an action referred to as echoing). Among other uses, the ping protocol allows hosts to determine round-trip times to other machines. Do not modify the attached server code. In this server code, 30% of the client’s packets are simulated to be lost. The server sits in an infinite loop listening for incoming UDP packets.
