Dialog box
—An on-screen box
that either requests or provides
information. For instance, if you choose
the Export .CSV command, a dialog box
appears asking for the name of the file
you wish to export.
Dimmed
—Unavailable. A command
or option that is currently unavailable is
dimmed (shown in gray) on the screen.
Direct access
—A method of
selecting a menu or option by pressing
ALT followed by the key that
corresponds to the underlined letter in
the command, menu, or option name. In
some instances, you might have to
press a key combination such as
Shift+letter.
Directory
—A location in a disk’s
file system; a collection of files and
subdirectories that are stored at the
same location on a disk. The name of
the directory identifies its location. See
also subdirectory.
Disk drive
—A device for storing
and retrieving data on disks. Hard disks
are disk drives with disks permanently
sealed inside. Floppy disk drives use
floppy disks, that you can insert and
remove. See also floppy disk.
DOS prompt
—A letter followed by
a colon that appears at the left edge of
the screen when using the DOS
operating system. The letter identifies
the active drive. For example, A:, C:.
Double-click
—To position the
pointer on an object you want to select,
and then click twice in quick succession.
This action carries out a command.
Export
—To move data into a file that
other applications can use.
Extension
—A period followed by
three letters at the end of a filename.
Extensions identify what kind of
information a file contains. For example,
the extension .CSV indicates that the
elements in the file are separated by
commas. The extension .EXE identifies
a file that the system can use to start up
a program (EXEcutable).
Field
—An item of data. A group of
related fields make up a record. For
example, each file you create in the
CytoFluor System has fields for name,
assay, laboratory, plate, filter sets, and
so on.
File
—An organized collection of
information given a name and stored on
a disk. Files can be programs, data,
operating systems, and so on.
File name
—The name of a file.
Windows uses DOS file naming
conventions; therefore, filenames
usually consist of a base name with no
more than eight characters and an
extension made up of a period and
three characters. For example,
LABTEST.CSV. See also extension.
Floppy disk
—A disk that you can
put into and take out of a disk drive. The
disk itself is made of flexible plastic, as
compared to the disks in hard disk
drives, which are made of metal. Floppy
disks originally had only thin, flexible
jackets and were literally floppy. These
disks now more commonly have rigid
plastic jackets with a sliding metal
access slot.
