Computer files are binary, measured as a power of 2 so 1 MiB = 1,048,576 bytes. This is unlike Base 10 numbers where for example 1 Megapixel = 1,000,000 pixels.

1 Kibibyte (KiB) = 1024 Bytes
1 Mebibyte (MiB) = 1024 KiB
1 Gibibyte (GiB) = 1024 MiB
1 Tebibyte (TiB) = 1024 GiB
1 Pebibyte (PiB) = 1024 TiB
1 Exbibyte (EiB) = 1024 PiB

Many documents still refer to byte measues with the old-style prefixes: Bytes,KB,MB,GB… but these are case sensitive and easily confused with bits: Bits,Kb,Mb,Gb…
Bytes are used to measure file sizes.
bits are used to measure network or download speeds.
1 Byte = 8 Bits, 1 MiB = 8 Mb
