T1   -   The common name for a digital signal circuit with 1.44 Megabits/second in full duplex bandwidth. A T1 is made up of twenty-four 8-bit channels.

T3   -   The common name for a digital signal circuit with 44.736 Megabits/second in full duplex bandwidth. A T3 is made up of up to twenty-eight T1 signals.

TATRC   -   The Telemedicine and Advanced Technology Research Center performs medical reconnaissance and special operations to address critical gaps that are underrepresented in DoD medical research programs. TATRC fosters research on health informatics, telemedicine/m-Health, medical training systems, and computational biology.   See DoD

Taxonomy   -   The practice and science of classification. Also used as a noun to describe a taxonomic scheme (e.g., "A Functional Taxonomy of Rule-based Decision Support Content" by Wright, Goldberg, et al.).   See Concept, Hierarchy, Ontology, Semantics, Terminology

TCP   -   Transmission Control Protocol, defined in 1981 by RFC 793.   See RFC

TCP/IP   -   Transmission Control Protocol/Internet Protocol.   See Internet Protocol, TCP

Telco   -   Old slang for TELecommunication COmpany.

Telecom   -   Short for telecommunications.   See BSS, OSS

Telehealth   -   The delivery of health care services and information via telecommunication technologies. Telehealth can be as simple as a professional consult by telephone, or as complex as remote control of surgery robots. Telehealth solutions enable the delivery of clinical care at a distance into locations where patient access to care is compromised by transportation challenges (e.g., islands, rural communities, etc.).   See Remote Presence

Telemedicine   -   See Telehealth

Template   -   EHRs frequently include blank electronic templates (i.e., forms) optimized to enable prompt documentation of clinical observations during a patient examination. However, CMS discourages templates with limited options, such as predefined answers, checklists, or limited space for documentation. See CMS, EHR

Terminology   -   The study of terms and their use, where "terms" are words or word compounds.   See Attribute, Concept, Hierarchy, Ontology, Semantics, Taxonomy

TJC   -   See Joint Commission

TLS   -   Transport Layer Security, the successor crytographic protocol to SSL, providing endpoint authentication and communications confidentiality with standard security certificates at 1024 or 2048 bit strengths, per RFC 5246.   See IETF, RFC, SASL, SSL

Touchscreen   -   An electronic visual display that can detect the presence of a touch within the display area.   See GUI

Trial Implementation   -   The second stage in the development of the Nationwide Health Information Network (NwHIN) was the Trial Implementation project. The set of information exchanges and Federal agencies in this project worked together as the "NHIN Cooperative" to securely exchange data including summary patient records for providers and patients. The project ran from 2007 to 2009.   See CONNECT, DURSA, eHealth Exchange, Healtheway, LBNH, NHIN, NwHIN, Onboarding, ONC, Prototype Architecture

Triple Aim   -   A framework developed by the Institute for Healthcare Improvement (IHI) that describes a proven and practical approach to optimizing health system performance.   See IHI

Trojan Horse   -   A computer program that appears harmless but is actually malicious. Due to the popularity of botnets among hackers and the availability of advertising services that permit authors to violate user privacy, trojan horses are a common nuisance.   See Malware

Tuple   -   In a relational database model a tuple is a finite function that maps attributes to values.   See Key-value, NoSQL

TXT   -   [1]   "txt" is the universal file name extension for flat files structured as a series of lines of text. Taken strictly, "text file" refers to a flat file container, while "plain text" is a type of content. [2] TXT is a self-referential name for abbreviations and slang commonly used in IM or mobile phone text messaging, which employs creative alphanumeric combinations to shorten words (e.g., compressing "see you later" into l8r or "ok" into k). Txt messaging usage initially exploded under the voice-centric mobile phone market and has now migrated into mobile data txt services accessed via wi-fi from smart phones or tablets, including chat tools in social media apps (e.g., Facebook, Twitter, etc.).   See IM, OMG, SMS

Type I Error   -   Also known as an "error of the first kind," a Type I error is a false positive. Lowering the probability of a Type I error (a false positive) generally also raises the probability of a Type II error (a false negative)   See Error, False Positive, Specificity

Type II Error   -   Also known as an "error of the second kind," a Type II error is a false negative. Lowering the probability of a Type II error (a false negative) generally also raises the probability of a Type I error (a false positive)   See Error, False Negative, Sensitivity
