T's Flashcards
TA
(Terminal Adapter)
An external appliance or a plug-in card for a PC or compatible router that facilitates an ISDN connection.
TB
(Thunderbolt)
It can be used as a display interface (like DisplayPort) and as a general peripheral interface (like USB 3).The latest version uses USB-C connectors.
TCO
(total cost of ownership)
The cost of a device over its lifetime, including the cost of replacement components and consumables.
TCP
(Transmission Control Protocol)
A protocol in the TCP/IP suite operating at the transport layer to provide connection-oriented, guaranteed delivery of packets. Hosts establish a session to exchange data and confirm delivery of packets using acknowledgements. This overhead means the system is relatively slow.
TCP/IP Suite
(Transmission Control Protocol/Internet Protocol suite)
The network protocol suite used by most operating systems and the Internet. It is widely adopted, industry standard, vendor independent, and open. It uses a 4-layer network model that corresponds roughly to the OSI model as follows: Network Interface (Physical/Data Link), Internet (Network), Transport(Transport), Application (Session, Presentation, Application).
TFT Active Matrix Display
(Thin Film Transistor active matrix display)
The TFT display provides the best resolution of all of the currently available flat-panel Liquid Crystal Display (LCD)designs, although they are also the most expensive. TFT displays offer very high image clarity, contrast ratios of between150:1 to 200:1, fast refresh rates, and wide viewing angles.
THD
(Total Harmonic Distortion)
A sound measurement that is expressed as a percentage that compares input and output audio signals, which indicates the amount of distortion in the output signal.
TKIP
(Temporal Key Integrity Protocol)
Mechanism used in the first version of WPA to improve the security of wireless encryption mechanisms, compared to the flawed WEP standard.
TLD
(Top Level Domains)
In the DNS hierarchy, the level immediately below the root.
TLS
(Transport Layer Security)
A security protocol that protects sensitive communication from eavesdropping and tampering by using a secure, encrypted, and authenticated channel over a TCP/IP connection.
TN
(Twisted Nematic)
An LCD panel technology where the panel is black when no electric current is running through the liquid crystal cells because the cells align themselves in a twisted state. When an electric current is applied, the liquid crystal cells untwist, allowing light to passthrough, resulting in a white display screen.
TPM
(Trusted Platform Module)
A specification for hardware-based storage of digital certificates, keys, hashed passwords, and other user and platform identification information. Essentially, it functions as a smart card embedded on a motherboard.
