Critical Thinking Questions Case 2 You've begun work as a consultant to individuals and businesses, making recommendations to them about the kinds of systems they should buy and what equipment they should have. Aaron is a user who travels extensively. Which of the following is he NOT likely to need?

Question 8

Critical Thinking Questions Case 1 In all of the advertisements for personal computers, vendors usually state the type of hard disk interface supported by the hard disk controller, so it is important that you understand the types of available hard disk interfaces, so you can make the most informed choice possible. You are in the market for a disk controller that will support a high number of peripheral devices. What disk controller will do the trick?

Accepted Answer

SCSI (Small Computer System Interface) is the best choice for supporting a high number of peripheral devices, as it has a high transfer rate and allows for multiple devices to be connected to the controller. EIDE (Enhanced Integrated Drive Electronics) and SATA (Serial Advanced Technology Attachment) both support single device connections, while USB (Universal Serial Bus) is not typically used for connecting hard disk controllers.

Question 10

Critical Thinking Questions Case 1 In all of the advertisements for personal computers, vendors usually state the type of hard disk interface supported by the hard disk controller, so it is important that you understand the types of available hard disk interfaces, so you can make the most informed choice possible. After more consideration, you have decided that what you want most is an interface that is less susceptible to interference. Which of the following is your best bet in this regard?

Accepted Answer

SATA (Serial ATA) is designed to replace the older parallel ATA (PATA) standard. It offers several advantages over PATA, SCSI, and EIDE interfaces, including longer cables that are less susceptible to electromagnetic interference, which makes it the best choice for minimizing susceptibility to interference.
