ICT (information and communications technologies) is an umbrella term that includes any communication device or application , encompassing: radio, television, cellular phones, computer and network hardware and software, copper, optical, wireless, satellite systems and so on, as well as the various services and applications associated with them.
Telecommunications, also called telecommunication, is the exchange of information over significant distances by electronic means. A complete, single telecommunications circuit consists of two stations, each equipped with a transmitter and a receiver. The transmitter and receiver at any station may be combined into a single device called a transceiver. The medium of signal transmission can be electrical wire or cable (also known as "copper"), optical fiber or electromagnetic fields . The free-space transmission and reception of data by means of electromagntetic fields is called wireless.
RSS (RDF Site Summary - formerly called Rich Site Summary or Really Simple Syndication) is a method of describing news or other Web content that is available for "feeding" (distribution or syndication) from an online publisher to Web users.
A Web site that wants to "publish" some of its content, such as news headlines or stories, creates a description of the content and specifically where the content is on its site in the form of an RSS document.
The publishing site then registers its RSS document with one of several existing directories of RSS publishers.
A user with a Web browser or a special program that can read RSS-distributed content can read periodically-provided distributions.
Some current directories of RSS files include Meerkat, GropSoup, NewsIsFree, UserLand, and XML Tree; these sites are sometimes known as content aggregators. Web based aggregators include My Yahoo! and Google Reader.
You can feed discussion forum excerpts, software announcements, etc - ny form of content retrievable with a URL can be RSS fed.

Digital audio files can contain, in addition to the audio track, related text and/or graphical information. The information you're probably familiar with take the form of Song title, Artist name, Album name, Year and Genre. This is the information displayed when you playback a digital audio file on your computer or portable device. The process of including information other than sound into these digital audio files is commonly referred to as "tagging" in which you "tag" the audio file with additional information that describes the audio file. The original standard for tagging digital files was developed in 1996 by Eric Kemp and he coined the term ID3. At that time ID3 simply meant " ID entify an MP 3 ".
