Storage Requirements
Computer Science: Cambridge International GCSE, topic 1.3.16
Storage Requirements
To calculate the amount of data that can be stored within a certain capacity, you need to know three things:
Size of data being stored
- The bigger the size of the data being stored, the bigger capacity media will be needed.
Available capacity
- The more capacity available, the more data we can store.
How to convert between the units
- To find out if we have enough capacity, it is important to put the capacity of the media and the size of the data into the same units.
Test yourself on Storage Requirements
I need to download two videos, of average size 500 MB. What is the approximate total amount of data that I will download?
An online video streaming service sends data at 4 MB per second. I only have 180 MB of data left. How long will I be able to watch the stream for?
