Glossary of Computer Terms—T
T
T1: An Internet
backbone line that carries up to 1.536 million bits per second (1.536Mbps).
T3: An Internet line
that carries up to 45 million bits per second (45Mbps). That’s 160 times as
fast as a 28.8k modem!
TCP/IP: Stands for
Transmission Control Protocol/Internet Protocol. This is a large grouping of
programs and standards that govern how information moves round the Internet.
The protocols were established around 1970-1980 to allow computers to attach to
one another.
TERABYTE (TB): It’s about a
trillion bytes. Actually it’s 2 to the 40th power or 1,009,511,627,776 bytes.
TERAFLOP: A measure of a
computer’s speed. It can be expressed as a trillion floating-point operations
per second.
TERMINAL
EMULATION: This is an application that allows your terminal to
act as a dumb terminal.
TEXT EDITOR: See EDITOR.
TELNET: An Internet
protocol that let you connect your computer as a remote workstation to a host
computer anywhere in the world and to use that computer as if you were logged
on locally.
THIRD-PARTY
SOFTWARE: Software developed by a software company rather
than by a computer manufacturer or user.
THREAD: In online
discussions, a series of messages that have been posted as replies to each
other. A single forum or conference typically contains many threads covering
different subjects. By reading each message in a thread, one after the other,
you can see how the discussion has evolved. You can start a new thread by
posting a message that is not a reply to an earlier message.
THROUGHPUT: The number of
instructions executed per second, measured in millions of instructions per
second (MIPS) or billions of instructions per second (BIPS).
TOGGLE: To switch back
and forth between two states or conditions of operation, as in a toggle switch.
TOP-DOWN
HIERARCHICAL DESIGN: A hardware and/or software design approach that
starts at the most general level of a machine or software program. It proceeds,
step-by-step, to lower levels, adding detail as the design progresses.
TRACK: A ring on the
surface of a magnetic disk.
TRACKBALL: Input device
that controls the position of the cursor on the screen; the unit is mounted
near the keyboard, and movement is controlled by moving a ball.
TRACTOR-FEED: A pin-fed
device for advancing continuous form paper through a computer printer.
TRANSISTOR-TRANSISTOR
LOGIC (T2L): A logic gate family that provides higher-speed and
higher-power than the obsolete DTL logic family. The first transistor in the
circuit performs the required logic. Another transistor amplifies and inverts
the output. Improved pin-compatible versions of this logic family are called
TTL-Schottky (T2L-S) and Low Power TTLS (LPT2L-S).
TRANSLATOR: See ASSEMBLER,
MACROASSEMBLER, INTERPRETER, and COMPILER.
TRANSPARENT: Something that
occurs without being known to the user.
TRI-STATE LOGIC:
The term that designates the possible conditions of a specific logic
gate output: “0”, “1” or “undefined”.
TROJAN: A type of
computer virus that is loaded into an unsuspecting users system via a host
program such as a free game. The Trojan can be programmed by the author to
perform many actions once activated by the user. These actions usually have
malicious intent. The term “Trojan” comes from ancient Greece, where the Greeks
used a wooden horse containing hidden Greek soldiers to gain entrance to the
city of Troy.
TRUNCATE: The dropping of
digits or characters from one end of a data item causing loss of accuracy or
information.
TRUTH TABLE: A tabulation of
all possible combinations of states at the inputs of a logic gate which will
result in a specific logic state at the output of the gate.
TURNKEY SYSTEM: A complete
computer system ready to operate without any hardware or software modification
or addition.
TWAIN: Stands for Technology Without An Interesting Name. I like this, I found it on another site.
