10-82 Chapter 10 Managing Data Storage
formatting Preparing a hard disk to accept data by creating a file system (such as
NTFS or FAT) on that disk.
fragmentation Occurs when files are frequently added and removed from the disk,
or when the disk begins to fill up. In both of these cases, it can be difficult for the
operating system to locate a contiguous area of the disk to write to, and data can
become fragmented.
logical partition A disk storage area that you create within an extended partition on
a basic Master Boot Record (MBR) disk. Logical drives are similar to primary partitions,
except that you can create an unlimited number of logical drives per disk.
A logical drive can be formatted and assigned a drive letter.
mounted volume A volume to which you assign a path on an existing volume
rather than a drive letter.
NTFS compression A function of the NTFS file system that performs dynamic compression
and decompression on folders and files marked with the compression
attribute.
Offline Files A feature of Windows XP Professional that makes temporary copies of
shared network files on a local computer so that you can access those files when
the local computer is disconnected from the network.
primary partition A partition that you can configure as the active, or bootable,
drive. You can configure up to four primary partitions on a computer running a
Windows operating system (three partitions if you also have an extended partition
on the disk).
recovery agent A user account that is given the capability to decrypt an encrypted
file or folder in case the owner of the resource loses the file encryption certificate
that allows decryption.
removable storage A storage device that allows you to remove either the device
itself or the storage media that the device uses.
simple volume A dynamic volume that contains disk space from a single disk and
can be extended if necessary.
spanned volume A dynamic volume that contains disk space from 2 or more (up to
a maximum of 32) disks. The amount of disk space from each disk can vary. There
is no fault tolerance in spanned volumes. If any of the disks containing the
spanned volume fail, you lose all data in the entire spanned volume.
striped volume A dynamic volume that contains disk space from 2 or more (up to
a maximum of 32) disks. Unlike spanned volumes, striped volumes require that
you use an identical amount of disk space from each disk. Striped volumes provide
increased performance because it is faster to read or write two smaller pieces
of a file on two drives than to read or write the entire file on a single drive. However,
you cannot extend striped volumes and they provide no fault tolerance.
