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,

You had the following information: The capacity of an iPhone is measured in gigabytes (GB). The iPhone in question has 8GB of storage. A gigabyte is about 1,000 megabytes (MB) The phone already has 3GB of stuff on it One minute of video takes 150MB of space Exercise Create a string that tells the user how many minutes of video they can store on the phone. You'll first need to perform the calculation steps, then use string interpolation to display the answer - which should look like this: You can record XXX more minutes of video. Hint: Do all of your calculations in megabytes. 17 18 19 20 21 22arrow_forward
