Expert Solution & Answer
Chapter 3, Problem 1RQ
Program Description Answer
OUI of MAC address is unique.
Hence, the correct answer is option “B”.
Expert Solution & Answer
Explanation of Solution
The OUI:
- • OUI in networking stands for Organizationally Unique Identifier.
- • It is the memory of first 24 bits of a Media Access Control (MAC) address that is used for identifying a vendor uniquely.
- • It is the first three parts of 8bits each used for data communication in computing.
- • It is used in finding the Network Interface Controller (NIC) manufacturer.
Explanation for incorrect options:
The network identifier:
The network identifier is used for finding the computers or devices present on any local network or intranet.
Hence, the option “A” is wrong.
The device identifier:
The device identifier is used for categorizing the devices.
Hence, the option “C” is wrong.
The physical address:
A physical address is used for defining and understanding a cell which is related to main memory.
Hence, the option “D” is wrong.

Make a database with multiple tables from attributes as shown above that are in 3NF, showing PK, non-key attributes, and FK for each table? Assume the tables are already in 1NF. [Hint: 3 tables will result after deducing 1NF -> 2NF -> 3NF]
Please answer the JAVA OOP Programming Assignment scenario below:
Patriot Ships is a new cruise line company which has a fleet of 10 cruise ships, each with a capacity of 300 passengers. To manage its operations efficiently, the company is looking for a program that can help track its fleet, manage bookings, and calculate revenue for each cruise.
Each cruise is tracked by a Cruise Identifier (must be 5 characters long), cruise route (e.g. Miami to Nassau), and ticket price. The program should also track how many tickets have been sold for each cruise.
Create an object-oriented solution with a menu that allows a user to select one of the following options:
1. Create Cruise – This option allows a user to create a new cruise by entering all necessary details (Cruise ID, route, ticket price). If the maximum number of cruises has already been created, display an error message.
2. Search Cruise – This option allows to search a cruise by the user provided cruise ID.
3. Remove Cruise – This op…
