XIII Chapter 0100: Test for Success Answers
1. The IDE interface competes with the ATA standard.
Explanation: ATA and IDE are two names for the same standard.
2. IDE is an acronym for (Choose all that apply)
A. Industrial Drive Electronics
B. Integrated Drive Electronics
C. Intelligent Drive Electronics
D. Institutional Drive Electronics
Explanation: IDE stands for Integrated Drive (or Device) Electronics.
3. EIDE is incompatible with the ATA standard
Explanation: Many ATA compatible devices are also EIDE compatible.
4. ATAPI added support for
A. SCSI CD-ROM
B. IDE CD-ROM
C. MFM CD-ROM
D. RLL CD-ROM
Explanation: The AT Attachment Packet Interface (ATAPI) standard allowed CD-ROM drives to use IDE technology.
5. PIO is an acronym for:
A. Preferred Industry Organization
B. Primary In Out
C. Preferential Input Output
D. Programmed Input Output
Explanation: PIO stands for Programmed Input Output. It defines that the device must send data to the CPU.
6. Ultra DMA supports data transfer rates up to:
A. 8 MB per second
B. 16 MB per second
C. 33 MB per second
D. 66 MB per second
Explanation: Ultra DMA supports transfer rates of 33 and 66 MHz. Newer UDMA technology supports up to 100/133 MHz transfers.
7. Choose the appropriate characteristics for Ultra ATA/66 (Choose all that apply)
A. Bypasses CPU
B. Requires a minimum of 32 MB of RAM
C. A maximum transfer rate of 66.7 MB per second
D. Requires 80 conductor cabling
Explanation: Ultra ATA66 allows the drive to write data directly to RAM, bypassing the CPU. It allows transfer rates of 66.7 MB/s, and uses an 80-wire, 40-pin cable.
8. A color-coded 80-conductor IDE cable uses a _______ color for the system board; __________ color for the first drive and a ________ color for the second drive, if it exists.
A. Black, gray, blue
B. Blue, gray, black
C. Gray, black, blue
D. Blue, black, gray
Explanation: On a UDMA 66 cable, the blue connector goes to the motherboard, the black connector goes to the first drive, and the gray connector goes to the second drive.
9. An 80-conductor IDE cable can support C/S.
Explanation: UDMA 66 cables can support cable select (CS) as long as the color specifications are followed.
10. A single IDE Channel can support up to
A. One drive
B. Two drives
C. Three drives
D. Four drives
Explanation: A single IDE channel can support up to 2 drives, a master and a slave.
11. It is possible to have both a C/S and a non-C/S drive in a computer, as long as they are on different channels.
Explanation: The master/slave and CS configurations are ways of designating which drive in the chain is being used as the controller. As long as CS and Master/Slave settings are not mixed in a channel, both can be used in a system.
12. The maximum cable length for IDE is
A. 12 in.
B. 18 in.
C. 24 in.
D. 36 in.
Explanation: The maximum length of an IDE cable is 18 in.
13. Serial ATA is incompatible with current IDE standards.
Explanation: Because it is a completely new interface standard, Serial ATA drives will be incompatible with IDE cables and controllers.
14. Ultra IDE/66 and Ultra IDE/100-133 use 80 conductors with 40 pins to:
A. Make everyone wonder what happened to the other 40 wires
B. Carry the required DC voltage
C. Reduce crosstalk
D. Interface with 80 pin SCSI drives
Explanation: The extra 40 wires are for ground, which reduces crosstalk.
15. A read/write head meeting the platter while spinning is called a:
A. Hard Drive dance
B. Advanced Data Transfer
C. Landing Zone
D. Head Crash
Explanation: When a head comes in contact with a platter, it is called a head crash. This will destroy any data that is stored in the affected area.
16. The track on the outermost ring on a platter is called Track
Explanation: The first track on a platter is Track 0. It contains the Master Boot Record (MBR).
17. CHS is short for:
A. Complete Head System
B. Cylinder Head Sector
C. Compressed Head Storage
D. Circular Head System
Explanation: CHS stands for Cylinder Head Sector. It is an addressing scheme used by older systems to find a particular location on the hard drive where data is stored.
18. True of False. LBA is in part, a translation scheme.
Explanation: Logical Block Addressing (LBA) is a method of addressing a location of data on a hard drive. It uses serially numbered sectors as opposed to CHS addressing.
19. Track 0 contains
B. OS Information
C. Nothing because this is the Landing Zone
D. Secret pictures of Tcats office
Explanation: Track 0 contains the MBR, which has boot information for the OS.
20. _______ requires 2 drive controllers.
A. RAID 1 Duplexing
B. RAID 0
C. RAID 1
D. RAID 5
Explanation: RAID 1, mirroring, requires only 1 controller. Disk Duplexing is RAID 1 with two controllers.
