Introduction

In a SCSI-2 system, a computer with a host-adapter serves as the
primary initiator for all actions on the SCSI bus. All other devices
connected to the bus are SCSI targets. Figure 1-2 above illustrates a
simple configuration where a host computer is connected to a
single target, a disk drive with an embedded SCSI controller. The
controller can be a stand-alone device with multiple peripherals as
shown in Figure 1-3.
