Social Bookmarking A centralized online service which enables users to add, annotate, edit, and share bookmarks of web documents Delicious, founded in 2003, popularized the terms "social bookmarking" and "tagging Tagging is a significant feature of social bookmarking systems, enabling users to organize their bookmarks in flexible ways and develop shared vocabularies known as folksonomies Unlike file sharing, social bookmarking does not save the resources themselves, merely bookmarks that reference them, i.e. a link to the bookmarked page 5.

PodcastAlso known as netcast A digital medium consisting of an episodic series of audio, video, PDF, or ePub files subscribed to and downloaded through web syndication or streamed online to a computer or mobile device "podcasting" was first mentioned by Ben Hammersley in The Guardian newspaper in a February 2004 article, along with other proposed names for the new medium. It is a portmanteau of the words "pod" from iPod and "broadcast 7. VoIPa methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, IP communications, and broadband phone service. 8. Online Chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver may address point-to-point communications as well as multicast communications from one sender to many receivers and voice and video chat, or may be a feature of a web conferencing service The first online chat system was called Talkomatic, created by Doug Brown and David R. Woolley in 1974 on the PLATO System at the University of Illinois. The first dedicated online chat service that was widely available to the public was the CompuServe CB Simulator in 1980, created by CompuServe executive Alexander "Sandy" Trevor in Columbus, Ohio. 9. WWW(abbreviated as WWW or W3, commonly known as the web) A system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them via hyperlinks. Had a number of differences from other hypertext systems available at the time. The web required only unidirectional links rather than bidirectional ones, making it possible for someone to link to another resource without action by the owner of that resource It also significantly reduced the difficulty of implementing web servers and browsers (in comparison to earlier systems), but in turn presented the chronic problem of link rot 10. StreamingStreaming media is multimedia that is constantly received by and presented to an enduser while being delivered by a provider. Its verb form, "to stream", refers to the process of delivering media in this manner; the term refers to the delivery method of the medium rather than the medium itself. In the early 1920s, George O. Squier was granted patents for a system for the transmission and distribution of signals over electrical lines which was the technical basis for what later became Muzak, a technology streaming continuous music to commercial customers without the use of radio. From the late 1980s through the 1990s, consumer-grade personal computers became powerful enough to display various media. The primary technical issues related to streaming were: having enough CPU power and bus bandwidth to support the required data rates creating low-latency interrupt paths in the operating system to prevent buffer underrun. However, computer networks were still limited, and media were usually delivered over non-streaming channels, such as by downloading a digital file from a remote server and then saving it to a local drive on the end user's computer or storing it as a digital file and playing it back from CD-ROMs. 11. Blog(a truncation of the expression web log) is a discussion or informational site published on the World Wide Web and consisting of discrete entries ("posts") typically displayed in reverse chronological order (the most recent post appears first). The term "weblog" was coined by Jorn Barger on 17 December 1997. The short form, "blog", was coined by Peter Merholz, who jokingly broke the word weblog into the phrase we blog in the sidebar of his blog in April or May 1999. Shortly thereafter, Evan Williams at Pyra Labs used "blog" as both a noun and verb ("to blog", meaning "to edit one's weblog or to post to one's weblog") and devised the term "blogger" in connection with Pyra Labs' Blogger product, leading to the popularization of the terms. 12. Social Networking A platform to build social networks or social relations among people who, for example, share interests, activities, backgrounds, or real-life connections. A social network service consists of a representation of each user (often a profile), his social links, and a variety of additional services. Most social network services are web-based and provide means for users to interact over the Internet, such as e-mail and instant messaging. Online community services are sometimes considered as a social network service, though in a broader sense, social network service usually means an individual-centered service whereas online community services are group-centered. Social networking sites allow users to share ideas, pictures, posts, activities, events, and interests with people in their network. 13. URLuniform resource locator, abbreviated URL (also known as web address, particularly when used with HTTP) a specific character string that constitutes a reference to a resource. In most web browsers, the URL of a web page is displayed on top inside an address bar. The Uniform Resource Locator was standardized in 1994 by Tim Berners-Lee and the URI working group of the Internet Engineering Task Force (IETF) as an outcome of collaboration started at the IETF Living Documents "Birds of a Feather" session in 1992 (or news feed) is a data format used for providing users with frequently updated content. Content distributors syndicate a web feed, thereby allowing users to subscribe to it. Making a collection of web feeds accessible in one spot is known as aggregation, which is performed by an aggregator. A web feed is also sometimes referred to as a syndicated feed. Confusion between Web feed and RSS The term RSS is often used to refer to web feeds or web syndication in general, although not all feed formats are RSS. The Blogspace description of using web feeds in an aggregator, for example, is headlined "RSS info" and "RSS readers" even though its first sentence makes clear the inclusion of the Atom format: "RSS and Atom files provide news updates from a website in a simple form for your computer." 14.
