Diskeeper 10 User's Manual

86 Glossary
fragmentation: The word fragmentation means “the state of being fragmented.” The word fragment means “a
detached, isolated or incomplete part.” It is derived from the Latin “fragmentum,” which in turn is derived from
“frangere,” meaning “break.” So, fragmentation means that something is broken into parts that are detached,
isolated or incomplete.
gigabyte: A measure of computer storage capacity equal to approximately a billion bytes. A gigabyte is two to
the 30th power, or 1,073,741,824 bytes.
graphical user interface (GUI): Pronounced “gooey.” A user interface, as used in the Windows operating
systems, which uses a mouse and graphic displays to interact with the user, with the purpose to make the
computer system easier to use than other operating systems, such as MS-DOS.
GUI: See graphical user interface.
hard disk: One or more rigid metal platters, coated with magnetic material. Contrast with floppy disk, or
diskette, which is made of plastic. Also used to refer to the physical unit that makes up a disk drive.
hardware: The physical parts of a computer system, including devices such as printers and disk drives.
Contrast with software.
I-FAAST: A Diskeeper exclusive, Intelligent File Access Acceleration Sequencing Technology (I-FAAST)
improves file access and creation on NTFS volumes by up to 80% (average 10%-20%) above and beyond the
improvement provided by defragmentation alone. This is the first industry implementation of “Disk
Performance Calibration”, the modern evolution of the outdated and inconclusive disk optimization strategies
of the past.
I/O Smart: The Diskeeper I/O Smart feature intelligently monitors drive access during defragmentation to
ensure top system speed. When this option is selected, Diskeeper will temporarily suspend defragmentation
whenever other disk activity needs to occur (I/O throttling). This proprietary technology detects whether or not
the disk is busy with other I/O requests and pauses defragmentation to eliminate any potential interference with
user or system needs at the “disk” level.
IDE: Integrated Device Electronics. One of several types of interfaces between a disk drive and a computer,
where the controller is built into the disk drive, which eliminates the need for a separate controller card in the
computer. See also ATA and SCSI.
integrated circuit: Also called a chip. A collection of electronic parts with a specific purpose, built into a
single physical package. See also central processing unit.
Intel: Manufacturer of processor chips, known especially for the Pentium and x86 processors.
interface: The connection and interaction between hardware, software and/or the user. For example, a disk
controller provides a physical interface between a computer and a disk drive. The keyboard, mouse and display
are an interface between a computer and the user.
Internet: A global network that links millions of computers. One popular section of the Internet is the World
Wide Web, which allows computer users to view text and pictures with the aid of a browser, such as Internet
Explorer. E-mail (electronic mail) is another popular part of the Internet, which allows computer users to send
and receive written messages.
Internet Explorer: A software package developed by Microsoft for browsing the Internet, but increasingly
used with other applications.
job: A request to have the computer or its peripherals perform some activity. In relation to Diskeeper, it is a
request to have a disk defragmented.
log file: A file that keeps track of certain events as they occur. The Windows NT/2000/XP operating system
maintains several log files that can be viewed with the Event Viewer. On Windows 98/Me systems, Diskeeper
uses a specially created text file for the same purpose. See also Event Logging.
