Blog

From Wikipedia, the free encyclopedia

A weblog (usually shortened to blog, but occasionally spelled web log or weblog) is a web-based publication consisting primarily of periodic articles, most often in reverse chronological order. Early weblogs were simply manually updated components of common websites. However, the evolution of tools to facilitate the production and maintenance of web articles posted in said chronological fashion made the publishing process feasible to a much larger, less technical, population. Ultimately, this resulted in the distinct class of online publishing that produces blogs we recognize today. For instance, the use of some sort of browser-based software is now a typical aspect of "blogging". Blogs can be hosted by dedicated blog hosting services, or they can be run using blog software on regular web hosting services.

Like other media, blogs often focus on a particular subject, such as food, politics, or local news. Some blogs function as online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic.

 

 

Podcasting

From Wikipedia, the free encyclopedia

Podcasting is the method of distributing multimedia files, such as audio programs or music videos, over the Internet for playback on mobile devices and personal computers. Podcasts are distributed using either the RSS or Atom syndication formats.

The term podcast, like "radio", can mean both the content and the method of delivery. The host or author of a podcast is often called a "podcaster".

Podcasters' web sites may also offer direct download or streaming of their files. However, a podcast is distinguished by its ability to be downloaded automatically using software capable of reading RSS or Atom feeds.

Usually the podcast features one type of "show", with new episodes either sporadically or at planned intervals, such as daily or weekly. In addition, there are podcast networks that feature multiple shows on the same feed. One can listen to a podcast either on a computer or on a mobile audio device (such as an iPod).

Podcasting's essence is about creating content (audio or video) for an audience that wants to listen or watch when they want, where they want, and how they want.

 

Wiki

From Wikipedia, the free encyclopedia

A wiki is a type of website that allows users to easily add, remove, or otherwise edit all content, very quickly and easily, sometimes without the need for registration. This ease of interaction and operation makes a wiki an effective tool for collaborative writing. The term wiki can also refer to the collaborative software itself (wiki engine) that facilitates the operation of such a website (see wiki software), or to certain specific wiki sites, including the computer science site (and original wiki), WikiWikiWeb, and the online encyclopedia Wikipedia. When used to refer to a specific site, wiki is often capitalized.

The word wiki is a shorter form of wiki wiki (weekie, weekie) which is from the native language of Hawaii (Hawaiian), where it is commonly used as an adjective to denote something "quick" or "fast" (Hawaiian dictionary). In English, it is an adverb meaning "quickly" or "fast".

In essence, a wiki is a simplification of the process of creating HTML pages combined with a system that records each individual change that occurs over time, so that at any time, a page can be reverted to any of its previous states. A wiki system may also include various tools, designed to provide users with an easy way to monitor the constantly changing state of the wiki as well as a place to discuss and resolve the many inevitable issues, namely, the inherent disagreement over wiki content. Wiki content can also be misleading, as users are bound to add incorrect information to the wiki page.

Many wikis will allow completely unrestricted access so that people are able to contribute to the site without necessarily having to undergo a process of 'registration', as had usually been required by various other types of interactive websites such as Internet forums or chat sites.

The first wiki, WikiWikiWeb, is named after the "Wiki Wiki" line of Chance RT-52 buses in Honolulu International Airport, Hawaii. It was created in 1994 and installed on the web in 1995 by Ward Cunningham, who also created the Portland Pattern Repository.
