Access to data on striped volumes is usually faster than on other types of dynamic volumes, because
it can be performed simultaneously on multiple hard disks.
Unlike a mirrored volume (p. 75), a striped volume does not contain redundant information, so it is
not fault-tolerant.
A striped volume is also known as a RAID-0 volume.
Swap file
A file (p. 72) that is used by an operating system to store data that does not fit in the physical
memory of the machine.
Use of the swap files enables more programs to run than would otherwise be allowed by the
memory limitations. The operating system unloads currently unneeded data to the swap file, and
loads needed data from the swap file into memory.
A swap file is also called a paging file.
System folder
A folder that contains files that are necessary for an operating system to work.
Examples of system folders for Windows operating systems are “Program Files” and “Windows”.
System volume
The volume which contains files that are necessary for any of the installed Windows operating
systems to start.
Examples of such files are: Boot.ini, Ntdetect.com, and Ntldr
If only one Windows operating system is installed on your machine, the system volume is usually the
same as the boot volume (p. 69).
If more than one Windows operating system is installed on your machine, each of these operating
systems normally has its own boot volume, whereas there is still only one system volume.
In terms of volume type, the system volume can be a primary volume on a basic disk, or a simple
volume on a dynamic disk.
See also boot volume (p. 69).
T
Track
Any one of the concentric circles to which a hard disk (p. 73) is divided.
Information from one track can be accessed without moving the magnetic head.
