Floppy Disk
: Also called a diskette. It is a
round disk with a hole in the middle, made of
flexible material and houses in a square
envelope or cartridge. A disk drive holds the
floppy disk through the hole in its center and
spins it within its envelope. They can be used
over and over again. Contrast with hard disk.
Flow control
: The process of regulating the
speed at which data enters or leaves a serial
port. Software flow control is implemented by
communications software or by the user sending
predefined characters or packets which are
recognized as “pause” and “resume” indicators.
Hardware flow control is achieved by using the
RTS (request to send) and the CTS (clear to
send) control lines of the RS-232 interface.
Footprint
: The desk or floor space that a piece
of hardware occupies. Also referred to as “real
estate”.
Foreground
: The application program
currently running on, and in control of, the PC
screen and keyboard. The area of the screen
that occupies the active window. Compare
with background.
Format
:
1. The way text is set up on a page.
2. To prepare a disk for holding information.
Formatting a disk can delete all information
that was previously on it.
3. The information is structured in a file, often
specific to one application or protocol.
Frequency
: A characteristic of an electrical or
electronic signal which describes the periodic
recurrence of cycles. Frequency is inversely
proportional to the wavelength or pulse width
of the signal.
FSK (Frequency Shift Keying)
: A technology
that establishes two frequencies used to
represent binary values. This was the earliest
type of modulation used by 300 bps modems.
Full-duplex
: A method of transmitting and
receiving data simultaneously over a single
pair of wires. Compare with Half-Duplex.
G
Gateway
: A workstation which serves as a
protocol converter (translator) between two or
more dissimilar networks, providing
incompatible systems.
H
Half-Duplex
: The transmission of data in both
directions, but only one direction at a time.
Compare with Full-Duplex.
Handshaking
: A process that two modems go
through at the time of call setup to establish
synchronization over the data communications
link. It is a synchronization and negotiation
process, accomplished by the exchange of
predefined, mutually recognized control codes.
Hard Disk
: A metal disk covered with
magnetic recording material. Some can hold up
to several gigabytes of information. Contrast
with floppy disk.
Hardware
: The equipment that makes up your
computer system, including the keyboard,
mouse, disk drives, and monitor.
Hexadecimal
: A base 16 numbering system used
to represent binary values. Hex uses the
numbers 0-9 and the letters A-f; usually notated
by an “h” (as in “4CF h”, read as “four charley
fox, hex”). The result is that one hex digit
represents a four-bit value.
Host
: The computer that is designated as
retaining information or processing power to
service the needs of other computers or
terminal. Mainframes and mid-range computers
are hosts, as well as PCs with powerful
microprocessors. Often a PC on a LAN will be
set up as a host to provide LAN access for
remote users.
I
I/O Addresses
: Locations within the I/O
address space of your computer used by a device,
such as an expansion card, a serial port, or an
internal modem. The address is used for
communication between software and a device.
Initialize
: To begin anew and establish start-
up parameters. This typically involves
clearing all or some part of the device’s memory
or disk space.
