What is RSS.??What is the important of RSS in WWW?
RSS = Real Simple Syndication it is a web feed used to publish news articles, pod casts, alerts, and pretty much anything that you want to push out. The way it works as when you go to a website that has an rss feed availble you can use certain programs to sign up for the feed, then when new info is available that program will automatically download this.

A good example is Itunes, in Itunes you can go to the store and sign up for free podcasts such as This Week In Tech then when a new podcast is released Itunes will automatically download it and put it in your library and inform you so you can listen to it. This is basically a very simple yet effective way for web publishers to push out their product to customers/subscribers with out them having to come to the original site everyday to check for updates
Reply:Think of RSS as a news subscription. You read a website on a regular basis, and it's updated pretty requently so you grab it's RSS feed with a News aggregator or a RSS client.

In the future, when your news aggregator is loaded up, it will scour all the sites you subscribed to and bring you all the new articles straight to your desktop without you having to go to each individual webpage for updates. You can read them all there at once.

Reply:RSS is a family of web feed formats used to publish frequently updated digital content, such as blogs, news feeds or podcasts.

Users of RSS content use programs called feed 'readers' or 'aggregators': the user 'subscribes' to a feed by supplying to their reader a link to the feed; the reader can then check the user's subscribed feeds to see if any of those feeds have new content since the last time it checked, and if so, retrieve that content and present it to the user.

Programs known as feed readers or aggregators can check a list of feeds on behalf of a user and display any updated articles that they find. It is common to find web feeds on major websites and many smaller ones. Some websites let people choose between RSS or Atom formatted web feeds; others offer only RSS or only Atom.

RSS-aware programs are available for various operating systems. Client-side readers and aggregators are typically constructed as standalone programs or extensions to existing programs such as web browsers and Email readers. Many browsers have integrated support for RSS feeds. There also are other applications that can convert an RSS feed into several usenet articles, viewable through the major newsreader software such as Mozilla Thunderbird or Forté Agent.

Web-based feed readers and news aggregators such as NewsGator Online require no software installation and make the user's "feeds" available on any computer with Web access. Some aggregators combine existing web feeds into new feeds, e.g., taking all football related items from several sports feeds and providing a new football feed. There are also search engines for content published via web feeds like Bloglines.

On Web pages, web feeds (RSS or Atom) are typically linked with the word "Subscribe", an orange rectangle, , or with the letters or . Many news aggregators such as My Yahoo![1] publish subscription buttons for use on Web pages to simplify the process of adding news feeds
