SCSI is an acronym for small computer system interface. It is the ability to use different structure of hard drives where the access of the hard drive is not restricted to only one interface. The SCSI has been around for a long time. It was popular in the 1980s and has been used for quite some time.

RAID, or redundant array of inexpensive disks, is used a lot now, and the technology is used in conjunction with virtual machines (VMs). RAID is used with virtualization software. You create virtual machines out of one physical machine by taking advantage of RAID. The RAID idea has been implemented in today’s computer architecture and organization.

Discuss the following questions and topics related to interface communications:

• Explain when you would use a SCSI drive.
• When you would have a need to use RAID? Explain.
• What is the difference between IDE (integrated drive electronics) and SATA (serial advanced technology attachment)?

Compare and contrast the different types of buses in a computer architecture. What are the uses for them?
