Logically, how is a SCSI bus mapped? Explain.
One-dimensionally. Basically, every device in the bus falls upon a straight line.
Each end of the SCSI bus must be terminated - and the bus must not fork or branch in any way. The word terminated refers to a special resistor pack that prevents signals from bouncing back and forth along the SCSI chain. The manual should contain information on how to terminate such a fork or branch.

When terminating, what parts of the chain must be terminated? What parts should not?
Devices mid-chain must not be terminated. Both ends of the SCSI chain must be terminated however. A SCSI host adapter qualifies as a device, so if it is at the end of the chain, it can be terminated.
Modern SCSI devices usually include a jumper or other setting to enable or disable termination.
