The data sizes:

- A bit is a single binary digit
- A nibble is half a byte (four bits)
- A byte is 8 bits
- A kilobyte is 1024 bytes
- A megabyte is 1024 kilobytes
- A gigabyte is 1024 megabytes
- A terrabyte is 1024 gigabytes
- (According to Wikipedia, it then goes Petabyte, Exobyte, Zettabyte, Yottabyte)
- 1024 times bigger each time

1024 is the magic number

- You’d think a kilobyte would be 1000 bytes, like how a kilogram is 1000 grams
- But it’s computers we’re talking about, here. They like binary.
- Remember in the converting binary post, the numbers doubled each time? 1024 is double 512, which is double 256, which is double 128, which is double 64, etc.
- 1024 is the closest power of 2 to 1000 so it is used instead of 1000
- REMEMBER: 1024
