;Why does storage come in the form of a number Which is always the exponential form of 2 ?

Question

Such as 8gbs, 16, 32 ,64 etc.

In: Technology

Answer 1

For physical hardware reasons.

If you imagine a very simple computer with 1 bit of storage, you need 1 physical *connection* to access it and it can be one of two things – a 0 or a 1, binary.

2 connections to 2 bits of storage gives *four* possible settings – 00, or 01, or 10, or 11.

3 connections to 3 bits of storage gives *eight* possible settings.

4 gives 16

5 gives 32

6 gives 64

(..)

32 connections to 32 bits gives 4,294,967,296 possible settings. Or 4 gigabytes.
