T-1
|
| |
A leased-line connection capable of carrying data at 1,544,000 bits-per-second. At maximum theoretical capacity, a T-1 line could move a megabyte in less than 10 seconds. That is still not fast enough for full-screen, full-motion video, for which you need at least 10,000,000 bits-per-second. T-1 is the fastest speed commonly used to connect networks to the Internet.

|
|
T-3
|
| |
A leased-line connection capable of carrying data at 44,736,000 bits-per-second. This is more than enough to do full-screen, full-motion video.

Tagged Image File Format (TIFF)
|
| |
Pronounced "tiff". A popular file format for bitmapped graphics that stores the information defining graphical images in discrete blocks called tags. Each tag describes a particular attribute of the image, such as its width or height, the compression method used (if any), a textual description of the image, or offsets from the start of the file to "strips" containing pixel data. 'Me TIFF format is generic enough to describe virtually any type of bitmap generated on any computer, but it is also complex and difficult to write software for.

| |
Measures stimulating diffusion and utilisation of technologies developed under RTD projects. A specific form of Accompanying Measure

Telematics
|
| |
Telematics combines wireless telecommunications and computers to convey information over vast networks efficiently.

|
Telephony Application Programming Interface (TAPI)
|
| |
A standard programme interface that lets people and their computer "talk" over telephones or video phones to people or phone-connected resources elsewhere in the world.
|
|
|
Token
|
| |
A "token" is an authentication too, a device utilised to send and receive challenges and responses during the user authentication process. Tokens may be small, hand-held hardware devices similar to pocket calculators or credit cards.

Transmission Control Protocol / Internet Protocol (TCP/IP)
|
| |
A set of communication protocols that allows dissimilar computers to share information over a network. TCP/IP is the transmission protocol used by the Internet.
|
|
|
Trapdoor
|
| |
A hidden flaw in a system mechanism that can be exploited to circumvent the systems security.

Trials (for users and suppliers)
|
| |
Type of Take-up measure supported by the Programme: See definition in Annex 1
|
|
|
Trojan Horse
|
| |
A computer program whose execution would result in undesired side effects, generally unanticipated by the user. Any program designed to do things that the user of the program did not intend to do or that disguise its harmful intent. The Trojan horse program may otherwise give the appearance of providing normal functionality
|
|
|
Tunnelling Router
|
| |
A router or system capable of routing traffic by encrypting it and encapsulating it for transmission across a non-trusted network, for eventual de-encapsulation and decryption.
|
|
|
Two-Factor Authentication
|
| |
Two-factor authentication is based on something a user knows (factor one) plus something the user has (factor two). In order to access a network, the user must have both "factors" - just as he must have an ATM card and a Personal Identification Number (PIN) to retrieve money from a bank account. In order to be authenticated during the challenge/response process, users must have this specific (private) information.
