Stands for File Allocation Table. Basically this is a table of contents
in a directory that tells the computer what all is in there. Look at your
Netscape cache, you'll see a FAT. It'll be the first file.
This was an older FAT (File Allocation Table) that was designed for use
in the MS-DOS system. FAT 16 was used in many Windows Operating Systems up
to Windows ME. Its biggest downfall was that it could only handle small
A new version of the file allocation table (FAT) available in Windows 95
OSR 2 and Windows 98. FAT32 increases the number of bits used to address
clusters and also reduces the size of each cluster. The result is that it
can support larger disks (up to 2 terabytes) and better storage efficiency
(less slack space).
The ability of a system to respond gracefully to an unexpected hardware
or software failure. There are many levels of fault tolerance, the lowest
being the ability to continue operation in the event of a power failure.
Many fault-tolerant computer systems mirror all operations -- that is, every
operation is performed on two or more duplicate systems, so if one fails the
other can take over.
Stands for Frequently Asked Questions. An FAQ is a file or document
where a moderator or administrator will post commonly asked questions and
A device you can attach to a personal computer that enables you to
transmit and receive electronic documents as faxes. A fax modem is like a
regular modem except that it is designed to transmit documents to a fax
machine or to another fax modem. Some, but not all, fax modems do double
duty as regular modems. As with regular modems, fax modems can be either
internal or external. Internal fax modems are often called fax boards.
Fiber Distributed Data Interface -- A standard for transmitting data on
optical fiber cables at a rate of around 100,000,000 bits-per-second (10
times as fast as Ethernet, about twice as fast as T-3).
A program found in all Aptiva software loads that allows modification of
the partitions and/or logical drives on the hard drive. It can Display,
Delete and Create partitions and logical drives, defining them for DOS, OS/2
or Windows, depending on which version of FDISK is used and how it is used.
Type FDISK and hit Enter to start the program. This is a DESTRUCTIVE command
and incorrect use will result in data loss!
The process of 'fetching' a data or instruction item from memory and
writing it to a register. The 'fetched' item is then either executed
(instruction), or acted upon (data).
An alternative to copper wire for transmitting information. In fiber
optics, pulses of light representing binary data are flashed along a
flexible glass fiber. The advantage over copper wiring is that a single
strand of optical fiber can carry thousands and thousands of different
frequencies at once without data loss.
This is the most important feature of the Internet. This is a method of
allowing one server to give the same file to many different end users.
A computer or a file storage device on a network that allows other
computers on the same network access to stored information and resources.
Software (programs or data) that has been written onto read-only memory
(ROM). Firmware is a combination of software and hardware. ROMs, PROMs and
EPROMs that have data or programs recorded on them are firmware.
This type of non-volatile memory has the ability to retain its
information even when there is no power source. Flash Memory is best known
for its use in hand help devices where it is used to store the operating
system and core applications. Other devices that use Flash Memory are:
-Cell Phones and Pagers
A graphical representation of planned activities, operations or tasks.
Usually, flow charts are used to show the progress of a certain activity.
They can also be used to show the variance between specific operations.
These specifications exist to satisfy predefined properties of a device
or program. The word "formal" in Computer Science is referring to the act of
being "precise". It takes three language components to make a specification
Grammatical structuring of data using a special code that defines how this
special code is used to form words, phrases or any other allowable
A relationship between words, phrases or any other allowable constraint and
their actual meaning. This is contrast to "Syntax". An example could be; if
you enter a misspelled command, it would be a syntax error, but if you enter
what may be a legitimate command but is not understood in its current
context, this would be a "semantics error".
3. Proof Theory:
This deals with the actual "logic" of the programming. Using mathematical
analysis techniques, the programming language is proof checked.
A web page element that uses text fields, radio buttons and check boxes
to process predefined data. Forms also allow users to interact with an
application by allowing information to be passed dynamically between two
FORmula TRANslator. Developed in 1954 by IBM, it is a high-level
programming language, most widely used for scientific and engineering
applications because it has excellent mathematical functions. Many
programmers consider it to sacrifice "elegance" for speed of numerical
This is a shortened version of Free Software. Programmers offer their
work without wanting pay in return.
This is the main pathway for data transfer in a PC. It connects all of a
computers major components, such as; memory, AGP socket and chipset.
Stands for File Transfer Protocol.
Refers to the transmission of data in two directions simultaneously. For
example, a telephone is a full-duplex device because both parties can talk
at once. In contrast, a walkie-talkie is a half-duplex device because only
one party can transmit at a time.
Most modems have a switch that lets you choose between full-duplex and
half-duplex modes. The choice depends on which communications program you
In full-duplex mode, data you transmit does not appear on your screen until
it has been received and sent back by the other party. This enables you to
validate that the data has been accurately transmitted. If your display
screen shows two of each character, it probably means that your modem is set
to half-duplex mode when it should be in full-duplex mode.
