CompTIA A+ Certification Core 1 (220-1101) - SCSI

The video tutorial explores the evolution of storage interfaces, starting with the ATA and SATA interfaces. It delves into historical storage devices like parallel ATA and SCSI, highlighting their differences and competition. The transition from parallel to serial connections is discussed, emphasizing the modern use of Serial Attached SCSI and iSCSI, particularly in server environments. The tutorial concludes with a focus on the relevance of these technologies in exams and the importance of understanding related terminology.

What does the ATA interface primarily control?

• Only hard disk drives

• Only SSDs

• Various hard disk drives and SSDs

• All types of network devices

What was a key difference between parallel ATA and SCSI in terms of system compatibility?

• They used the same controllers

• They were compatible with each other

• They required different controllers

• They could not be used in the same system

How many drives could a SCSI system support compared to a parallel ATA system?

• Up to 2 drives

• Up to 10 drives

• Up to 7 or 15 drives

• Up to 4 drives

What is a modern equivalent of SCSI that uses a serial connection?

• Parallel ATA

• Serial Attached SCSI (SAS)

• Ethernet SCSI

• USB SCSI

Where is iSCSI primarily used today?

• In desktop computers

• In server environments

• In mobile devices

• In gaming consoles
