Explanation

EIDE (Enhanced IDE), also known as PATA, uses physical jumpers on the drive to designate it as master or slave on a shared ATA channel, a configuration method unique to this interface.

Common mistakes.

A. USB drives are hot-plug devices that use a plug-and-play enumeration protocol; they have no jumpers or master/slave configuration.
B. SATA uses a dedicated point-to-point serial connection with one drive per port, eliminating the need for master/slave jumper settings entirely.
D. SCSI devices use a numeric SCSI ID (0-15) set via jumpers or switches to distinguish devices on the bus, but the terminology used is SCSI ID, not master and slave.

Concept tested. EIDE/PATA master-slave jumper configuration
