Technology [S-T]
Server
A computer or device on a network that manages network resources. For example, a file server is a computer and storage device dedicated to storing files. Any user on the network can store files on the server. A print server is a computer that manages one or more printers, and a network server is a computer that manages network traffic. A database server is a computer system that processes database queries. See also File server.
Simulations
Highly interactive applications that allow the learner to model or role-play in a scenario. Simulations enable the learner to practice skills or behaviors in a risk-free environment.
Skills inventory
An individual's list of skills or competencies, usually created by self-evaluation.
Source code
Program instructions written by a software developer and later translated(usually by a compiler) into machine language that a computer can understand.
Spam
(noun) Junk e-mail that is sent, unsolicited and in bulk, to advertise products or services or publicize a message. The term may have originated from a Monty Python skit.
(verb) To send unsolicited bulk e-mail to advertise products or services or publicize a message.
Specification
A plan, instruction, or protocol for e-learning that's established or agreed upon. Specification is often used interchangeably with standard, but the two terms are not truly synonymous. Specifications become standards only after they've been approved by an accrediting agency.
SMIL (Synchronized Multimedia Integration Language)
A markup language based on XML that allows you to create and stream web-based presentations composed of multiple media types, such as images, text, video, and audio.
Standard
An e-learning specification established as a model by a governing authority such as IEEE or ISO to ensure quality, consistency, and interoperability.
Streaming media (streaming audio or video)
Audio or video files played as they are being downloaded over the Internet instead of users having to wait for the entire file to download first. Requires a media player program.
Style sheets
In traditional print publishing and on the Web, style sheets specify how a document should appear, standardizing such elements as fonts, page layout and line spacing, repeated content, and so forth. Web style sheets help ensure consistency across web pages, but HTML coding can also override the sheets in designated sections of the pages.
Synchronous learning
A real-time, instructor-led online learning event in which all participants are logged on at the same time and communicate directly with each other. In this virtual classroom setting, the instructor maintains control of the class, with the ability to "call on" participants. In most platforms, students and teachers can use a whiteboard to see work in progress and share knowledge. Interaction may also occur via audio- or videoconferencing, internet telephony, or two-way live broadcasts.
24/7
Twenty-four hours a day, seven days a week. In e-learning, used to describe the hours of operation of a virtual classroom or how often technical support should be available for online students and instructors.
TCP (Transmission Control Protocol)
A protocol that makes sure that packets of data are shipped and received in the intended order.*
Teleconferencing
Two or more people who are geographically distant having a meeting across a telecommunications link. Includes audio conferencing, video conferencing, and/or data conferencing.
Telnet
The internet protocol in the TCP/IP suite that enables a user to interact with a program that is running in another computer; the name of the program used for remote login.
TIFF (Tagged Image File Format)
A widely supported file format for storing bit-mapped images on personal computers. TIFF graphics can be any resolution, black and white, gray-scaled, or color. Files in TIFF format usually end with a .tif extension. TIFF files are often used for archiving high quality versions of an image, such as images intended to be reproduced in print or studied digitally in minute detail.
Transcoding, transcoder
Converting a data stream from one format to another, such as MPEG 1 to H.263, or an H.320 videoconferencing session to H.323.
Trojan horse
A malicious computer program that appears legitimate but masks a destructive file or application. Unlike viruses, Trojan horses usually do not replicate themselves but can still cause a great deal of damage, such as creating an entryway into your computer for malevolent users.
Tutorial
Step-by-step instructions presented through computer or Web-based technology, designed to teach a user how to complete a particular action.
