Byte

A bit is the minimum amount of data existing in digital form. it is either true or false, 0 or 1. So, it has just two possible values.

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

Multiples of bytes have different names:

• 1 bit
• 8 bits = 1 Byte (on most systems)
• 1024 bytes = 1 KiloByte (KBytes or KB or KiB)
• 1024*1024 bytes = 1024 KB = 1 MegaByte (MBytes or MB or MiB)
• 1024*1024*1024 bytes = 1024*1024 KB = 1024 MB = 1 GigaByte (GBytes or GB or GiB)
• 1024*1024*1024*1024 bytes = 1024*1024*1024 KB = 1024*1024 MB = 1024 GB = 1 TeraByte (TBytes or TB or TiB)
• 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 or PiB)
• 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 or EiB)
• 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 or ZiB)
• 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 or YiB)
