How many devices can exist in a SCSI chain?

7 devices
8 devices
5 devices
10 devices

The correct answer is: 8 devices

In a SCSI (Small Computer System Interface) chain, up to 8 devices can be connected. This includes one SCSI host adapter (usually integrated into a computer or server) and up to 7 additional devices such as hard drives, CD-ROMs, or scanners. Each device in the SCSI chain is assigned a unique ID ranging from 0 to 7. SCSI's ability to connect multiple devices makes it particularly useful in environments where a variety of peripherals need to be managed by a single host. As the standard evolved, some SCSI variants allowed for even more devices, but the basic SCSI setup allows specifically 8 devices, confirming the answer.
