Answer:
Explanation:
a. In this scenario, the best solution would have an Object of Traditional Books, CD, Music, Bookstore and Customer.
b. All five objects would be able to be called by the main program loop and the Customer Object would call upon and use either the Books or CD object, While the Bookstore object would call upon all of the other objects.
c. Both the Bookstore object and Customer object will "have" other objects as the Bookstore needs to hold information on every Book or CD in the Inventory. While the Customer object would call upon the Book and CD object that they are purchasing.
d. The Music Object will extend the CD object and use information on the CD object as its parent class.
e. Since the Music Object extends the CD object it is also considered a CD since it is in CD format like the Books on CD and therefore is both objects.
Answer:
Option A is the correct answer choice for the above question.
Explanation:
The computer system needs intercommunication which is done inside the processor to process the task given by the user. There are two types of model is used for intercommunication--
- Message passing and
- Shared memory
The difference between two is that message passing passes the message on two points at a single unit of time whereas shared memory simultaneous shares the multiple messages. That's why shared memory is faster than message passing.
- Hence option A is the correct choice because it also refers to the above concept. While the other is not correct because--
- Option B states that message passing is faster than shared memory which is wrong.
- Option C states that message passing is used for large data but shared memory is used for large data.
- Option D states that shared memory is unavailable in some processor which is wrong.
