How to calculate the storage capacity of memory

The basic unit of memory storage capacity is bytes. However, due to the large storage capacity at present, KB, MB, GB and TB are commonly used as storage capacity units.

Conversion:

1B (bytes, bytes) = 8bit

1KB (kilobytes, kilobytes) =1024b = 210b;

1MB (megabyte, megabyte for short) =1024kb = 220b;

1GB (gigabyte, gigabyte, also called "gigabit") =1024mb = 230b;

1TB (terabyte, terabyte, terabyte) =1024gb = 240b;

1PB(Petabyte，Petabyte)= 1024 TB = 2 50b；

1EB (billion bytes, billion bytes, billion bytes) =1024pb = 260b;

1ZB(Zettabyte, 10 trillion bytes, zebyte) =? 65438+

Extended data

Megabyte (MB)= 1024KB is equivalent to the text content of a short story.

Gigabyte (GB)= 1024MB is equivalent to the score of the fifth movement of Beethoven's symphony.

Terabyte (TB)= 1024GB is equivalent to all the X-ray information of a large hospital.

Petabyte(PB)= 1024TB, which is equivalent to 50% of the information in American academic research libraries.

Ebyte =1024pb; 5EB is equivalent to what humans all over the world have said so far.

Zettabyte(ZB)= 1024EB, just like the sum of sand on beaches all over the world.

Yottabyte(YB)= 1024ZB, which is equivalent to the sum of microcells in 7000 people.
