Chapter 1, Problem 1RQE
Explanation of Solution
Difference between main memory and secondary storage:
| Main Memory | Secondary storage |
| In Main memory or Random Access Memory (RAM), the data is directly accessed by the processing unit. | In secondary storage, the data is transferred to the main memory and then routed to the processing unit. |
| Main memory is volatile, which means the information stored in the memory would be erased when the computer is turned off. | Secondary storage is non-volatile, which means the information stored in the memory is not erased when the computer is turned off. |
| Main memory has a limited storage capacity. | Secondary storage can store bulk amount of data in a single unit. |
| Main memory devices are more expensive when compared to the secondary storage devices. | Secondary storage devices are less expensive when compared to the main memory devices. |
|
The examples of main memory are,

The examples of secondary storage are,

Complete the JavaScript function addPixels () to calculate the sum of pixelAmount and the given element's
cssProperty value, and return the new "px" value.
Ex: If helloElem's width is 150px, then calling addPixels (hello Elem, "width", 50) should return 150px + 50px =
"200px".
