Kilobyte (KB)

1024 bytes make one kilo byte. Kilo Byte is denoted by KB.
1 KB = 1024 Bytes

Megabyte (MB)

1024 Kilo bytes make one mega byte. Mega Byte is denoted by MB.
1 MB = 1024 KB

Gigabyte (GB)

1024 mega bytes make one Giga byte. Giga Byte is denoted by GB. 
1 GB = 1024 MB

Terabyte (TB)

1024 Giga bytes make one Tera byte. Tera Byte is denoted by TB. 
1 TB = 1024 GB

Petabyte (PB)

1024 Tera Bytes make one Peta byte. Peta Byte is denoted by PB. 
1 PB = 1024 TB

Exabyte (EB)

1024 Peta bytes make one Exa byte. Exa Byte is denoted by EB.
