Computer Data Sizes
A bit is a single digit number (0 or 1)
8 Bits = 1 Byte (B)
1024 Bytes = 1 Kilobyte (KB/kB)
1024 Kilobytes = 1 Megabyte (MB)

1024 Megabytes = 1 Gigabyte (GB)
1024 Gigabytes = 1 Terabyte (TB)

1024 Terabytes = 1 Petabyte (PB)
1024 Petabytes = 1 Exabyte (EB)
1024 Exabytes = 1 Zettabyte (ZB)
1024 Zettabytes = 1 Yottabyte (YB)
 
* A bit is the smallest unit of computer data. While bits are often used to measure data transfer speeds, bytes are used to measure file sizes, hard disk space, and computer memory.
 
* The yottabyte is the largest unit of measurement for computer data.
