Explanation

SCSI (Small Computer System Interface) uses a device ID addressing scheme. Wide SCSI supports up to 16 devices on a single bus, with IDs ranging from 0 to 15 (the host adapter typically occupies ID 7). This ID must be manually set - traditionally via jumpers - to avoid conflicts on the bus. SATA uses point-to-point connections with no device ID numbering, USB uses dynamic addressing assigned by the host controller, and EIDE (Enhanced IDE) uses a master/slave configuration with only two positions per channel.
