CompTIA A+ Core 1: SCSI Device Cables Test and Flashcards

Define and Describe SCSI

Small Computer Systems Interface is a standard designed to string many peripheral devices into a SCSI chain

True or False: SCSI can operate in serial and parallel

True

How many devices can fit on a single SCSI bus for narrow and wide buses, respectively?

8 and 16

What is the biggest benefit of SCSI chains?

Each device is linked with each other allowing the configurer to bypass much of the initial setup work

Define and Describe LUNs

Logical Units, are SCSI devices defined and separated logically rather than physically, each device in a SCSI chain is assigned a unique SCSI ID, LUNs separated functions of these devices virtually to facilitate better communication between the chained devices

Define and Describe SAS

Serial Attached SCSI, are SCSI devices that have no jumpers, terminators, or discrete settings
