Question

Which of the following statements is correct regarding the difference between

Enhanced IDE and SCSI devices?

A. EIDE controllers are much faster than SCSI devices because they have to

handle a maximum of four devices.

B. The number of EIDE devices is limited to four, but there can be up to 31

SCSI devices in a system.

C. EIDE devices are connected in a daisy-chain fashion, but the SCSI devices

have to be configured as the master and slave.

D. EIDE devices require a separate IRQ and I/O address for each device, and

SCSI devices require only an ID.

Answer 1

B. The Enhanced IDE controller allows you to have a maximum of four

hard disk drives in a system. This limitation is overcome by the SCSI controller

that allows you to have up to 31 devices, depending on the type of controller

used. The latest Ultra-3 SCSI standard supports up to 32 devices.
