Chapter 1, Problem 1E
How does a computer’s main memory differ from its auxiliary memory?
Expert Solution & Answer
Explanation of Solution
Difference between main memory and auxiliary memory:
| Main memory | Auxiliary memory |
| It is directly accessible by the CPU. | It is not directly accessible by CPU |
| It contains the data to be processed by the computer and holds the result of the calculations. | Data which needs to be stored permanently is kept in the secondary memory |
| It is volatile in nature. | Auxiliary memory is non-volatile. |
| It could be accessed by the data bus. | It could be accessed by the input-output channels. |
| Data could be accessed in a faster rate. | Data accessed by the secondary memory is slower. |
| It is made up of semiconductors | It is made of magnetic and optical material. |

Java Graphics
(Bonus
In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to
implement the following:
A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a
Point (see java.awt.Point) in a PointCollection class (you need to build this).
The points need to be represented by circles.
Below the drawing panel, you will need 5 buttons:
O
о
о
○
An input button to register your mouse to the drawing panel.
A show button to paint the points in your collection on the drawing panel.
A button to shift all the points to the left by 50 pixels.
The x position of the points is not allowed to go below zero.
Another button to shift all the points to the right 50 pixels.
"
The x position of the points cannot go further than the
You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel
containing the buttons, and a GridLayout to hold the drawing panel and button panels.
Regardless of how…
