Module 2.3 - The Internet and the WWW Flashcards
Webinars
Online seminars which users in remote locations can participate in, using online conference technologies. These occur in real-time and allow ‘delegates’ access to interactive conferences and workshops.
Downloading
Transferring and saving an audio or video file from the Internet onto a computer, smartphone or tablet. You can then play the file at a later stage, or more than once, without being connected to the Internet.
JPEG
The most common file format used for digital photos or graphics, also widely used for graphics on websites. (JPEG files are also known as JPG files.)
Lossless compression
Compressing data without losing any portion of the data. It allows the exact original data to be reconstructed.
Mobile Internet access
The ability to connect to the Internet using wireless networks such as the cellular phone network. This is often referred to as mobile broadband Internet access.
MPEG-2
A standard used for the compression of video files and their associated audio tracks, and widely used to broadcast digital television.
Web 2.0
The next, and current, stage in the evolution of the WWW, characterised by more dynamic content and an interactive ‘read-write’ role on the part of the consumer public. Content consumers can become content creators as well, for example, on social networking sites.
WWW
World Wide Web - A service on the Internet. The WWW consists of a vast global collection of interlinked, interactive multimedia documents.
Audio and Video on Demand (AVOD)
Video on Demand (VOD) and Audio and Video on Demand (AVOD) are systems which allow users to watch video content and listen to audio content on demand.
Fixed location Internet access
High speed data transmission to homes and businesses using cabled technologies such as ADSL. This is often referred to as fixed broadband Internet access.
Web 3.0
The future of the WWW, in which exact directions are still uncertain, but which will certainly contain elements of artificial intelligence and a greater emphasis on personalised content; in other words less ‘reaction’ and more customised ‘prediction’ in favour of users. Web 3.0 will also be accompanied by enhancements in web-enabled devices, elimination of incompatibility issues, extensions in mobile capacity, and increases in bandwidth and speed.
MPEG-4
The latest and still developing standard used for the compression of audio and visual digital data through the use of lossy compression.
Lossy compression
Compressing data by sacrificing some insignificant or virtually undetectable portion of the data.
Web 1.0
Earliest stage in the evolution of the WWW, characterised by mostly static content and a ‘read-only’ role on the part of the consumer public.
Streaming
The immediate and real-time delivery of media content to a receiving device, starting from the time at which the media file is opened. The file is not saved to your device.
