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 order mark as a byte sequence in various encodings and how those sequences might appear in a text editor that is interpreting each byte as a legacy encoding (CP1252 and caret notation for the C0 controls): Byte order mark The byte order mark (BOM) is a Unicode character, , whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: BOM use is optional. Its presence interferes with the use of UTF-8 by software that does not expect non-ASCII bytes at the start of a file but that could otherwise
