Definition
don't know
A)
B)
C)
Term
Circle the correct answer.
The term (coercivity / retentivity) refers to how strongly magnetic domains resist changes to their polarity.
Definition
coercivity
Term
The term coercivity / retentivity refers to how effectively magnetic domains retain their positive or negative orientations (polarity) over time.
Definition
retentivity
Term
Circle the correct answers.
Larger capacity HDDs require magnetic domains with high / low coercivity, and thus consume more / less power.
Definition
high / more
Term
Circle the correct answer.
There is a direct relationship between the retentivity of the magnetic domains and the amount of time the material can retain the data. A high retentivity will result in more / less data degradation over time.

High-level
Term
Circle the correct answer.
One way to perform a high-level format on a hard drive is by using the (GUI / CMOS setup screen) during the installation of the operating system.

Term
The size of this unit is detetmined during a high-level format and consists of at least two sectors. It is the smallest amount of disk space that can be allocated to a file by the operating system.
Definition
Cluster
Term
Circle the correct answer.
The (operating system registry / file allocation system) determines the size of the cluster, or how many sectors comprise each cluster.
Definition
file allocation system
Term
Circle the correct answer.
A cluster is a logical / physical configuration of the hard drive.
Definition
logical
Term
Circle the correct answer.
A sector is a logical / physical configuration of the hard drive.
Definition
physical
Term
This road map is used by the operating system to locate files on the HDD.
Definition
File system
Term
Circle the correct answer.
The HDD maintains (two copies / one copy) of the file system.
Definition
two copies
Term
This is the name of the Mac OS X file system.
Definition
HFS+
Term
Check the two file systems that are recommended for use with Windows 2000 and Windows XP.
Definition
NTFS & FAT32
Term
This file system works with the Windows 2000 and XP operating systems. It stores data more efficiently, and provides better file security than FAT32.
Definition
HFS+
Term
This is the process of dividing a single physical hard drive into multiple smaller logical drives. A single logical drive may also be created through this process.
Definition
Partitioning
Term
This is the correct sequence of procedures for preparing a hard disk to accept an
operating system.
Definition
Partition, format, install OS
Term
Determine if each statement is true or false. If false, correct the statement. The integrated controllers on EIDE drives allow any EIDE hard drive to be attached to any ATX motherboard.
Definition
True
Term
Circle the correct answer.
EIDE mass storage devices using ATA100 and ATA133 require cables with 40 pins and
(40 / 80) wires to connect to the motherboard.
Definition
80
Term
Determine if each statement is true or false. If false, correct the statement.
Motherboard specifications may use the terms ATA, IDE, or DMA to refer to the EIDE hard drive technology supported by its chipset.
Definition
don't know
Term
Determine whether the hard drive technologies below employ a serial or a parallel interface.
a EIDE ________________________
b SATA ________________________
c SCSI ________________________
Definition
A) parellel
B) serial
C) parellel
Term
Circle the correct answer.
Each IDE connector on the motherboard can support two / four mass storage devices.
Definition
four
Term
This technology provides several smaller physical hard drives with the ability to function as a single logical drive.
Definition
RAID
Term
This ensures that the data in a RAID array will still be accessible if one of the disks fails by storing two copies.
Definition
Fault-Tolerance
Term
Determine if each statement is true or false. If false, correct the statement.
A system using RAID may take longer to boot. This is normal and is no cause for alarm.
Definition
true
Term
Determine if each statement is true or false. If false, correct the statement.
RAID configurations must be supported by a compatible motherboard chipset.
Definition
true
Term
These are the two types of RAID arrays that are most prevalent in today’s desktop PCs.
Definition
RAID-0 and RAID-1
Term
Although RAID-0 is the fastest and most efficient array type, it has this one major drawback.
Definition
It offers no fault-tolerance.
Term
Circle the correct answer.
Desktop PCs typically use software / hardware -based RAID, whereas servers use
software / hardware -based RAID.
Definition
hardware; software
Term
Circle the correct answer.
Software / Hardware -based RAID depletes system resources and competes with running
