Abbreviation for feet.
FTP
Abbreviation for file transfer protocol.
g
Abbreviation for gram(s).
G
Abbreviation for gravities.
guarding
A type of data redundancy that uses a set of physical drives to store data and a single, additional drive to store parity data. Data is protected from the loss of
a single drive. Guarding is sometimes preferred over mirroring because it is more cost-effective in systems with a very high storage capacity. However,
guarded configurations are significantly slower for applications that frequently write to the array because each attempt to the array requires multiple read and
write commands to maintain the parity information. If this is a problem, mirroring is a better choice. See also mirroring, RAID 4, and RAID 5.
GB
Abbreviation for gigabyte(s). A gigabyte equals 1,024 megabytes or 1,073,741,824 bytes.
Gb
Abbreviation for gigabit(s). A gigabit equals one billion bits.
graphics coprocessor
See coprocessor.
graphics mode
A video mode that can be defined as x horizontal by y vertical pixels by z colors.
h
Abbreviation for hexadecimal. A base-16 numbering system, often used in programming to identify addresses in the system's RAM and I/O memory addresses
for devices. The sequence of decimal numbers from 0 through 16, for example, is expressed in hexadecimal notation as 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E,
F, 10. In text, hexadecimal numbers are often followed by h.
headless system
A system or device that functions without having a keyboard, mouse, or monitor attached. Normally, headless systems are managed over an internet or
intranet network using an internet browser. Some systems provide for attaching a keyboard, mouse, and monitor for specific management or service needs,
others do not.
host adapter
A host adapter implements communication between the system's bus and the controller for a peripheral device. (Hard drive controller subsystems include
integrated host adapter circuitry.) To add a SCSI expansion bus to your system, you must install or connect the appropriate host adapter.
Hz
Abbreviation for hertz.
IDE
Abbreviation for integrated drive electronics
I/O
Abbreviation for input/output. A keyboard is an input device, and a printer is an output device. In general, I/O activity can be differentiated from computational
activity. For example, when a program sends a document to the printer, it is engaging in output activity; when the program sorts a list of terms, it is engaging
in computational activity.
ID
Abbreviation for identification.
interlacing
A technique for increasing video resolution by only up-dating alternate horizontal lines on the screen. Because interlacing can result in noticeable screen
flicker, most users prefer noninterlaced video adapter resolutions.
IP
Abbreviation for Internet Protocol.
