How much storage do you need for storing text graphics of vi

How much storage do you need for storing text, graphics, of video? Make assumptions; give an example of the size, and compute how many would fit in a 1 gig SD

Solution

In a 1 Giga Byte SD card, entire 1 Giga Byte might not be available for storage since system related files and recovery files will be present in the SD card. For calculations, I am assuming that entire 1 Giga Byte is available for storage.

1 Giga Byte = 1024 Mega Bytes = 1024 * 1024 Kilo Bytes = 1024* 1024 * 1024 Bytes

When dividing two entities, both should be in same units for easier calculation. Hence Giga Byte will be converted to Mega Bytes or Kilo Bytes as required.

Book with 1000 pages	PDF	800 Kilo Bytes	floor(1024 * 1024 / 800)	1310
A picture	JPEG	2 Mega Bytes	floor(1024/2)	512
A piece of music	MP3	6 Mega Bytes	floor(1024/6)	170
A piece of Audio/Video	MP4	15 Mega Bytes	floor(1024/15)	68
