To transfer data from a processing unit to an attached device. For example,
from a host to the terminal.
Data Set Ready. A hardware signal sent by a communications device to
indicate readiness to send and receive data.
Data Terminal Equipment. A device that acts as the source and/or
destination of data and which controls the communication channel. DTE
includes terminals, computers, protocol converters, and multiplexors. DTE is
usually connected via an RS-232 serial line to Data Communication
Equipment (DCE), typically a modem. It is necessary to distinguish these
two types of devices because their connectors must be wired differently if a
straight-through cable (pin 1 to pin 1, pin 2 to pin 2 etc.) is to be used. DTE
should have a male connector and should transmit on pin three and receive
on pin two. It is a curious fact that many modems are actually DTE according
to the original standard.
Data Terminal Ready. A hardware signal sent by a terminal to indicate
readiness to send and receive data.
A baseband local area network specification developed jointly by Digital
Equipment Corp., Xerox, and Intel to interconnect computer equipment
using coaxial cable and transceivers. An Ethernet LAN provides ten million
bits per second of capacity for high-speed terminal-to-computer
communication or computer-to-computer file transfer.
Federal Communications Commission. The Government body that regulates
all telecommunications originating in the U.S., including transmission over
telephone lines.
A computer program or software stored permanently in a PROM or ROM or
semi-permanently in an EPROM.
The procedure for regulating the flow of data between two devices, flow
control prevents the loss of data when one device's receiving buffer has
reached its capacity.
File Transfer Protocol. FTP is a program for transferring files in TCP/IP
environments such as the Internet in which a user, acting as a client,
downloads files from a remote server. FTP is a core component in every
TCP/IP system and is implemented at the Applications layer with respect to
the OSI protocol model. Its operation is based on the Telnet program and
TCP. FTP is available on a wide variety of computer systems and serves as
a common protocol for transferring files between systems.
Graphical User Interface (pronounced "gooey"). The use of pictures rather
than just words to represent the input and output of a program. A program
with a GUI runs under some windowing system (e.g. Microsoft Windows
The program displays certain icons, buttons, and dialog boxes in its windows
on the screen. The user mainly controls these objects by moving a pointer
on the screen (typically controlled by a mouse) and selecting certain objects
by pressing buttons on the mouse while the pointer is pointing at them.
Hertz. A unit of frequency equal to 1 cycle per second.
Independent Computing Architecture. A three-part server-based computing
technology that separates an application's logic from its user interface and
allows 100% application execution on the server.
