Blog 3: What "is Podcasting" ?
A podcast is a series of digital media files (either audio or video) that are released episodically and downloaded through web syndication.The mode of delivery differentiates podcasting from other means of accessing media files over the Internet, such as direct download, or streamed webcasting. A list of all the audio or video files currently associated with a given series is maintained centrally on the distributor's server as a web feed, and the listener or viewer employs special client application software known as a podcatcher that can access this web feed, check it for updates, and download any new files in the series. This process can be automated so that new files are downloaded automatically. Files are stored locally on the user's computer or other device ready for offline use, giving simple and convenient access to episodic content.Commonly used audio file formats are Ogg Vorbis and MP3.Researchers at the Center for Journalism and Communication Research at the University of Texas at Austin in the USA are proposing a four-part definition of a podcast: A podcast is a digital audio or video file that is episodic; downloadable; programme-driven, mainly with a host and/or theme; and convenient, usually via an automated feed with computer software.
Podcasts are digital media files (most often audio, but they can be video as well), which are produced in a series. You can subscribe to a series of files, or podcast, by using a piece of software called a podcatcher. Once you subscribe, your podcatcher periodically checks to see if any new files have been published, and if so, automatically downloads them onto your computer or portable music player for you to listen to or watch, whenever you wish.

Blog2. Reflect on what Web 2.0 is
- Web 2.0: It is commonly associated with web applications that facilitate interactive information sharing, interoperability, user-centered design, and collaboration on the World Wide Web.
- The concept of "Web 2.0" began with a conference brainstorming session between O'Reilly and MediaLive International. Dale Dougherty, web pioneer and O'Reilly VP, noted that far from having "crashed", the web was more important than ever, with exciting new applications and sites popping up with surprising regularity. What's more, the companies that had survived the collapse seemed to have some things in common. Could it be that the dot-com collapse marked some kind of turning point for the web, such that a call to action such as "Web 2.0" might make sense? We agreed that it did, and so the Web 2.0 Conference was born. In the year and a half since, the term "Web 2.0" has clearly taken hold, with more than 9.5 million citations in Google. But there's still a huge amount of disagreement about just what Web 2.0 means, with some people decrying it as a meaningless marketing buzzword, and others accepting it as the new conventional wisdom.
