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 serving data. It is often used when a server does not know exactly how much data there will be in the total response, allowing the server to start sending data to the client straight away without having to buffer the response and determine the exact length before it begins sending it to the client. This improves latency and reduces memory requirements while preserving the ability to reuse the connection after the response is completed. Byte serving and chunking are compatible and can be used with or without the other. Byte serving Byte serving (other names: RFC 7233 says the client makes
