What is "byte"
A byte is one of the types of integral data in computing. It is often used to specify the size or amount of the memory or storage capacity of a certain device, regardless of data type.
The standard byte encoding was defined to be 8 bits. The 8-bit byte is most commonly called Octeto in the context of computer networks and telecommunications.
To a half of a byte, it is given the name of Nibble or semioctecto.
Note that a byte is nothing special, it is only a binary number of eight digits. Its importance in computing derives only from the fact of the code ASCII have adopted eight-bit numbers, in addition to purely constructive or operational reasons.
