Which avenue may utilize video streaming, audio narration, print designs and animation?
Shtirlitz [24]

Answer:

Multimedia avenue.

Explanation:

A file type is the standard used to store data such as pictures, texts, videos, and audios. All file types have unique file extension that determine which program to use to open a particular file and to access its data e.g pictures (jpeg, png), texts (txt, docx, rtf), videos (mp4, 3gp, avi), audios (mp3, acc).

Sometimes, computer users make the mistake of opening files with the wrong software application or program, this often leads to an error due to the incompatibility of the software application with the particular file.

Basically, all software applications are designed and developed for use with specific file extensions or formats and as such, when used to open a file it isn't developed for, it result in an error.

A multimedia avenue refers to a channel that is designed and developed to accept, utilize and combine various file formats such as audio, video, text, animation effects, etc. A common example of a multimedia avenue is Microsoft PowerPoint software.

Hence, the multimedia avenue may utilize video streaming, audio narration, print designs and animation.

Design a software system for a bookstore that keeps an inventory of two types of books: Traditional books and books on CD. Books
Sophie [7]

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.
