What is the difference between octets and bytes?
An octet is a unit of digital information equal to 8 bits, while a byte is a unit of digital information typically composed of 8 bits. Therefore, in most cases, the terms octet and byte are used interchangeably. However, historically there have been instances where a byte could consist of 6, 7, or 9 bits, while an octet always refers to 8 bits.
