SCSI high byte termination case where there is only one 16-bit (wide) device connected to one or more 8-bit (narrow) devices. Then it is possible to wire all the eight spare data bits and the ninth parity bit together and to terminate them with a single resistor circuit to TERMPOWER. So in the case of a differential SCSI bus, it is possible to terminate all 18 spare signal wires with just one resistor. This method is not considered good practice, but has been successfully used in some SCSI products. SCSI high byte termination In SCSI computer systems, there is a special case with mixed
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
