Design of the FAT file system significant bits the second (f.e cluster 1). In other words, while the low eight bits of the first cluster in the row are stored in the first byte, the top four bits are stored in the low nibble of the second byte, whereas the low four bits of the subsequent cluster in the row are stored in the high nibble of the second byte and its higher eight bits in the third byte. The FAT16 file system uses 16 bits per FAT entry, thus one entry spans two bytes in little-endian byte order: The FAT32 file system uses 32 bits
Byte-oriented protocol bytes per code point. Byte-oriented protocol Byte-oriented framing protocol is "a communications protocol in which full bytes are used as control codes. Also known as character-oriented protocol." For example UART communication is byte-oriented. The term "character-oriented" is deprecated, since the notion of character has changed. An ASCII character fits to one byte (octet) in terms of the amount of information. With the internationalization of computer software, wide characters became necessary, to handle texts in different languages. In particular, Unicode characters (or strictly speaking code points) can be 1, 2, 3 or 4 bytes in UTF-8, and other encodings of Unicode
