REVIEWING THE BASICS
Name four ATA standards for interfacing with hard drives.
Possible answers: IDE/ATA, ATA-2, Fast ATA, Parallel ATA, EIDE, ATA-3, ATA/ATAPI-4,
Ultra ATA, Fast ATA-2, Ultra DMA, DMA/33, ATA/ATAPI-5, Ultra ATA/66, Ultra DMA/66,
ATA/ATAPI-6, Ultra ATA/100, Ultra DMA/100, ATA/ATAPI-7, Ultra ATA/133, Serial ATA
What are the two data transfer modes used by hard drives?
PIO and DMA
What are the two types of parallel ATA data cables used with hard drives?
80-conductor cable and 40-conductor cable
What is the name of the ATA standard that uses a serial data cable?
What are the two most popular spindle speeds measured in RPMs currently used for hard
5400 and 7200
How does serial ATA help keep a computer case cool better than parallel ATA?
Because serial ATA cables are thinner, they do not hinder air flow as much as wider parallel ATA
If a hard drive has three platters, how many heads does it have?
Given that there are 512 bytes per sector, calculate the hard drive storage for the
following: heads = 32, tracks (cylinders) = 1,024, sectors/track = 63.
What are three modes that system BIOS can use to relate to hard drives?
CHS mode, ECHS mode (large mode), or LBA mode
10. Which mode must be used for a 10-GB hard drive?
