An eight-bit binary word is often called a byte, and a four-bit binary word is called a nibble.
This new method involved a "5 and 3" split of the data bits, versus the "4 and 4" mentioned earlier. Each byte written to the disk contains five valid bits rather than four. This requires 410 "disk" bytes to store a 256 byte sector.
The terms "bits," "nibbles," "bytes," "halfwords," "words," and "doublewords" refer to lengths of 1, 4, 8, 16, 32, and 64 bits, respectively.

A data symbol represents one quartet (4 bits) of binary data; 16 symbols are thus required to convey data.
As a rule, the term hexadecimal is abbreviated to hex. Since there are 16 possible combinations of 4 bits (2×2×2×2), hexadecimal notation allows four bits of a binary number to be represented by one hex digit. […] For this reason, binary is almost never used. Instead, we use hex as a shortcut to eliminate the necessity of reading, writing and remembering long strings of bits.
Comme un caractère de la chaîne LM représente un quartet et que l'on veut créer une chaîne comme résultat on va coder 2 quartets par 2 quartets (1 caractêre ASCll=2 quartets=1 octet).[Since each character in the LM string represents a quartet, and we want to create a string as the result, we will encode the quartets in pairs (1 ASCII character = 2 quartets = 1 byte).]
Es gibt 10 verschiedene Dezimalziffern. Mit 4 Dualstellen lassen sich 24 = 16 Kombinationen bilden, also miissen 4 Dualstellen geniigen, um eine Dezimale zu verkörpern. Eine solche Vierergruppe wird als Tetrade bezeichnet.[There are 10 different decimal digits.

Memorize the decimal values for the high nibble (they're just the multiples of 16). The low nibble is trivial. Every number between 0 and 255 is the sum of one of the high nibble values and one of the low nibble values.

[…] As David Benson, a Washington State University professor, remembered it, he had jokingly made a remark in 1958 about "half a byte" (i.e., "half a bite") being a nibble, and the name stuck.
The characteristic eight bit field is sometimes referred to as a byte, a four-bit field can be referred to as a nibble.
Character – A group of 4 contiguous bits of data.(N.B. This Intel 4004 manual uses the term character referring to 4-bit rather than 8-bit data entities. By 1974, Intel had already switched to use the more common term nibble for 4-bit entities in their documentation for the succeeding 4040 processor.)
PRE.NYBBLE and POST.NYBBLE convert between memory format and disk format. […] PRE.NYBBLE converts the 256-byte buffer to 410 bytes of 5-bits each, then […] POST.NYBBLE converts the 410 5-bit values back to 256 8-bit bytes.
