[1] Priority - the order at which contentions on the bus are resolved
[2] Narrow Addresses - IDs from 0 to 7 available on a narrow bus
[3] Wide Address Range - IDs from 0 to 15 available on a wide bus
The following diagram below shows the linear addressing of a simple, narrow bus with the host bus adapter set at a
SCSI ID of 7. Seven other target devices are set to the remaining IDs. Note that the ID of the device does not determine
where the device is physically placed on the bus.

Initially, the SCSI specification defined a 5 MB/s synchronous data transfer rate on the narrow bus. SCSI now also
defines “Fast” which is 10 MB/s on a narrow bus and 20 MB/s on a wide bus. Another definition is “Ultra,” also known
as “Fast-20” which is 20 MB/s transfer rate on a narrow bus and 40 MB/s on a wide bus.
