what is web 2.0

The term "Web 2.0" (2004–present) is commonly associated with web applications that facilitate interactive information sharing, interoperability, user-centered design, and collaboration on the World Wide Web. Examples of Web 2.0 include web-based communities, hosted services, web applications, social-networking sites, video-sharing sites, wikis, blogs, mashups, and folksonomies. A Web 2.0 site allows its users to interact with other users or to change website content, in contrast to non-interactive websites where users are limited to the passive viewing of information that is provide to them.

Characteristics

Web 2.0 websites allow users to do more than just retrieve information. They can build on the interactive facilities of "Web 1.0" to provide "Network as platform" computing, allowing users to run software-applications entirely through a browser. Users can own the data on a Web 2.0 site and exercise control over that data. These sites may have an "Architecture of participation" that encourages users to add value to the application as they use it.
The concept of Web-as-participation-platform captures many of these characteristics. Bart Decrem, a founder and former CEO of Flock, calls Web 2.0 the "participatory Web” and regards the Web-as-information-source as Web 1.0.
The impossibility of excluding group-members who don’t contribute to the provision of goods from sharing profits gives rise to the possibility that rational members will prefer to withhold their contribution of effort and free-ride on the contribution of others. This requires what is sometimes called Radical Trust by the management of the website. According to Best, the characteristics of Web 2.0 are: rich user experience, user participation, dynamic content, metadata, web standards and scalability. Further characteristics, such as openness, freedom and collective intelligence by way of user participation, can also be viewed as essential attributes of Web 2.0.

selain itu ciri-ciri web 2.0 juga seperti:

1.) Mengandungi aplikasi web yang mempunyai ciri-ciri dan berfungsi seperti aplikasi pada komputer desktop.
Boleh dijalankan terus melalui web browser dan tidak memerlukan install software pada PC.
Contoh seperti aplikasi javascript, java applets, php dan yang sebagainya. Saya tidak akan membincangkan technicalities dalam hal ni, tapi jika anda membuka apa-apa website seperti YouTube, iTunes dan sebagainya, anda akan dapat melihat aplikasi tersebut
berfungsi secara real-time.
2.) User-generated content (interactivity): Membolehkan pengunjung memberi pandangan, komen, menulis artikel dan sebagaimana seperti yang ada pada blog, forum, Friendster, MySpace, Squidoo dan sebagainya. Jika dalam web 1.0, penggunjung hanya membaca artikel pada website, dalam web 2.0, penggunjung juga boleh menjadi subscriber dan contributor. Juga termasuk platform photo-sharing seperti Flickr dan video-sharing seperti YouTube, GoogleVideo.
3.) Membolehkan pengguna berkait antara satu sama lain. Platform yang boleh digunakan termasuklah MyBlogLog,
untuk blogs, atau add-a-friend seperti pada Friendster atau MySpace. Berbeza dengan link biasa, pengkaitan adalah interactive dan dalam contoh MyBlogLog, membolehkan pengguna mengisi maklumat peribadi dan melihat perkaitan atau pertalian diantara dia dan pengguna-pengguna lain.
4.) Penggunaan RSS feed dan RSS reader pada web site atau blog. Boleh memberi instant maklumat kepada pengunjung bila sesebuah site di update. Pengunjung tidak perlu lagi taip URL dan memeriksa sesebuah website setiap hari kalau-kalau pemilik site tersebut ada menulis artikel baru.
5.) Penggunaan skrip Open Source (OS), sama ada secara keseluruhannya atau separa-OS. Skrip pada wordpress.org, wiki, mozilla, sourceforge dan sebagainya.
6.) Penggunaan Folksonomy seperti tagging, tag clouds dan sebagainya untuk memberi kategori kepada webpage, links dan photos.
7.) User-friendly interface. Tidak seperti web 1.0 yang selalunya tidak berapa user-friendly, Web 2.0 sites memudahkan sesiapa saja menggunakannya kerana ia merangkumi ciri-ciri WYSIWYG (what you see is what you get). Tengoklah Friendster – nak bina Friendster site begitu mudah untuk beginner!
8.) Clean layout. Easy navigation. Tidak complicated.

dan untuk paham lebih jelas web 2.0 adalah sebuah revolusi bisnes di dalam industri komputer yang terjadi akibat pergerakan ke internet sebagai platform, dan suatu usaha untuk mengerti aturan-aturan agar sukses di platform tersebut.

difference between web2.0 and web1.0

The web as is stands (Web1.0) is seen as a "static" thing, like a billboard or a magazine. You can see lots of billboards, buy lots of magazines, enjoy or dislike them but they stay the same until they are changed by the publisher.

"Web2.0 applications" are ones that are "user-generated" or "user-shaped". Instead of being "published" by someone, the people using the site "publish" the content. They also market it and edit it.

Famous examples of "Web2.0 applications" already in use and much talked about are Flickr for photographs, Wikipedia for encyclopedia articles, Facebook for maintaining friendships, YouTube for seeing young people mugging to videocameras and Answers.com for combining syndicated elements of these with its own user-generated Q&A section.


Web 1.0 is like a kind of platform where there are new releases of it. But there is nothing like a new release for the existing ones in web 2.0. Web 2.0 is a kind of service oriented. Web 1.0 was about publishing, not participation; that advertisers, not consumers, ought to call the shots; that size mattered, and that the internet was increasingly being dominated by the top websites. Web 2.0 helps to increase the participation of the users like blogs, e-commerce websites, torrents etc, where every user gets a chance to publish in a website one way or the other.
