In the following assume that we are illustrating encapsulations of header / trailers for various protocols. We use H to indicate a Header and T to indicate a Trailer, for each of the protocols Eth (Ethernet), TCP, UDP and IP. Use M for a message that is send by an application layer. Which encapsulation would be a correct one?

In the 802.11 CSMA/CA protocol several Interframe intervals are defined. The following is typically the shortest:

The table in an Ethernet learning bridge consists of:

In Module 12, we discussed the Sendai Framework for addressing global natural disaster risk management.  Which of the following are the “Priorities for Action” of the Sendai Framework?

In Module 12, we discussed the Sendai Framework for addressing global natural disaster risk management.  Which of the following are the global targets of the Sendai Framework? I.  Reduce global disaster mortality. II.  Reduce damage to critical infrastructure/basic services. III.  Increase international cooperation.

From the Global Risks Report 2024, which of the following are things that could constrain or prevent the proper guardrails being put in place with regard to artificial intelligence (AI)?

Which of the following statements best describes the dynamic nature of intermediate filament assembly and disassembly?

Which structure of the tRNA base-pairs with the complementary mRNA sequence?   

In this part, you will write the implementation of the method below. Your implementation should be consistent with the class you’ve written in a prior step (i.e., only use the field(s) and method(s) that exist in the MyBookingScheduler class). You do not need to include any import statements or Javadoc comments in your response. T cancel(T booking) throws IllegalArgumentException, NoSuchElementException Removes and returns the booking in the system that is equal to the booking passed in. Remaining bookings should be shifted towards the beginning of the system. This method MUST use the cancel(int index) method to perform the removal! HINT: the implementation of this method is simple if you’ve implemented the cancel(int) and indexOf(T) methods. Think about how you can use these two methods to find and remove a booking that is equal to the argument (and throw the required exceptions, if necessary).  You can also rely on the propagation of exceptions, where appropriate. method throws IllegalArgumentException when the argument is null. The message should contain text describing the reason the argument is illegal. You may assume that IllegalArgumentException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. method throws NoSuchElementException when a booking equal to the argument doesn’t exist within the system. You may assume that NoSuchElementException is an unchecked exception and has a constructor that takes in a single String parameter representing the message.

In this part, you will write the implementation of the MyBookingScheduler class and its nested inner class MyBookingSchedulerIterator. DO NOT implement the BookingScheduler interface methods here. You should only provide the following in your response: the class header necessary field(s) HINT: the booking count of the system isn’t the same as the length of the backing array. You’ll want to keep track of the logical count of the collection using a private field. required Iterable method(s) complete MyBookingSchedulerIterator class implementation You do not need to include any import statements or Javadoc comments in your response. The requirements for the MyBookingScheduler class are as follows: MyBookingScheduler will support the interface below. Make sure that you are not using any raw types (i.e., you must use the generic type parameter in your solution). public interface MyBookingScheduler extends Iterable { … } The MyBookingScheduler class must have ONE private array that is used to store the bookings of the system in ascending (i.e., least-to-greatest) order. This class must also have a single, no-argument constructor that creates the generic array of type T with an initial length of 10. No other constructors should be written. NOTE: For ease of implementation, you can assume that new T[length] is valid syntax for creating a new array of type T. You can earn 5 bonus points if you know the correct way to create a new array of a generic type that will compile in Java. The MyBookingScheduler class should also have a nested inner class named MyBookingSchedulerIterator that satisfies the requirements of the Iterator interface. The iterator should iterate over the bookings in the system in ascending (i,e, least-to-greatest) order. Remember that nested inner classes have access to the private data members of the enclosing class! (i.e., the iterator will be able to access the backing array and any other fields the system class has) Think carefully about what state information an iterator will need to iterate over an array, and don’t overcomplicate it. Don’t forget that one of the Iterator methods should throw a NoSuchElementException when the iterator is asked to return a booking that doesn’t exist! The message should tell the user that the system contains no more bookings. IMPORTANT: DON’T FORGET TO IMPLEMENT THE METHOD(S) REQUIRED BY THE Iterable INTERFACE!
