Glossary
DSP Digital Signal Processor.
EPA Environment Protection Agency.
Sets standards, such as the Energy Star
Award.
Error correction A method used to
detect errors and have erroneous data
resent by a modem.
Escape characters A sequence of
three characters that switches the
modem from Data Mode to Command
Mode while maintaining the telephone
connection.
Extended MIDI format Allows
MIDI channels 1 to 10 of the General
MIDI operation mode to be used when
notes are played through MIDI.
Fallback Allows your modem to
reduce its speed when called by a
slower modem. Your modem will also
fallback automatically if poor-quality
telephone lines are hampering data
transmission.
Flow control Controls the amount of
data sent from your system to your
modem to ensure that the data does not
exceed the capacity of the modem
buffer. If your modem receives more
data than its buffer can hold, the
modem turns on flow control to
temporarily stop the flow of data from
the system. After the modem has
transmitted enough buffered data, the
buffer will be able to hold more data,
and the modem will turn off flow
control and resume the flow of data
from the system.
FM synthesis A technique for
synthesizing sound that uses a
combination of modulated sine waves
to produce different wave forms.
Full-duplex Simultaneous,
independent, two-way transmission
between communicating devices, such
as modems and systems.
General MIDI format A standard
set of 128 sounds. Allows 16 channels to
be used when notes are played through
MIDI.
Handshaking The exchange of
predetermined audible tones to set up
and control communications between
two modems.
Hard disk Storage device for PC
providing read and write storage. This
is one type of mass storage device.
Hardware flow control A flow
control method that modems use to
temporarily stop data transmission so
they can process the data that has
already been received.
IDE Integrated Device Electronics. A
protocol for communications between
the computer and a disk drive.
I/O address Input/Output address.
Address that defines the channel used
between the main processor and a
peripheral component.
IRQ Interrupt Request. A signal that,
when received by the processor, halts
the current process and allows a
different task to be undertaken.
ISA Industry Standard Architecture.
Standard for PC bus architecture.
