Byte

A byte is the minimum amount of data that a computer can access. Usually this is 8 bits, but it may vary on some systems.

Multiples of bytes have different names:

• 1024 bytes = 1 KiloByte (KBytes or KB)
• 1024*1024 bytes = 1024 KB = 1 MegaByte (MBytes or MB)
• 1024*1024*1024 bytes = 1024*1024 KB = 1024 MB = 1 GigaByte (GBytes or GB)
• 1024*1024*1024*1024 bytes = 1024*1024*1024 KB = 1024*1024 MB = 1024 GB = 1 TeraByte (TBytes or TB)
• 1024*1024*1024*1024*1024 bytes = 1024*1024*1024*1024 KB = 1024*1024*1024 MB = 1024*1024 GB = 1024 TB = 1 PetaByte (PBytes or PB)
• 1024*1024*1024*1024*1024*1024 bytes = 1024*1024*1024*1024*1024 KB = 1024*1024*1024*1024 MB = 1024*1024*1024 GB = 1024*1024 TB = 1024 PB = 1 ExaByte (EBytes or EB)
• 1024*1024*1024*1024*1024*1024*1024 bytes = 1024*1024*1024*1024*1024*1024 KB = 1024*1024*1024*1024*1024 MB = 1024*1024*1024*1024 GB = 1024*1024*1024 TB = 1024*1024 PB = 1024 EB = 1 ZettaaByte (ZBytes or ZB)
• 1024*1024*1024*1024*1024*1024*1024*1024 bytes = 1024*1024*1024*1024*1024*1024*1024 KB = 1024*1024*1024*1024*1024*1024 MB = 1024*1024*1024*1024*1024 GB = 1024*1024*1024*1024 TB = 1024*1024*1024 PB = 1024*1024 EB = 1024 ZB = 1 YottaByte (YBytes or YB)
