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.
In general, synchronous communication means you have to wait for the answer all the time. The programming logic is simpler, but the cost that you spend a lot of time waiting.
If the options are:
<span>a. The people communicating don't need to be online at the same time.
b. There is lag time in the communication.
c. The communication occurs in real time.
a is false, you do need to be online to receive the message
b is true, typically you continue only after an acknowledgement
c is true, you wait for acknowledgement that occurs in real time (not necessarily fast though)</span>

Answer:
CJ is developing a new website blogging about cutting-edge technologies for people with special needs. He wants to make the site accessible and user friendly. CJ wants to link to articles in his website. He has assigned specific values for each ID attribute. To link to that ID attribute, CJ must use an # before the ID value in his href statement.
Explanation:
In order to create an internal link, a link's href element must be assigned to a hash symbol #, including the value of the id attribute for the element that is to be to internally linked to, usually further down the page. Then, there is also a need to add the same id attribute to the element to be linked to.
An id refers to an attribute that uniquely describes an element. Below is an example of an internal anchor link and its target element:
<a href="#contacts-header">Contacts</a>
