Web 2.0

Web 2.0 is the current status of the web as it evolves into Web 3.0. This version of the World Wide Web encompasses collaboration and community, and the use of web-based applications through the Internet as opposed to a traditional computer program.

Community
Users of the Web 1.0 were simply "read-only" users with minimal input to the web interface, whereas Web 2.0 users have greater input in terms of sharing and collaboration. Web 2.0 brought about the possibility for web-based communities. This means that users can post their individual views and opinions on a single page about a specific topic. Commonly known as forums, users can converse with postings of varying times, from almost any location in the world, and share almost any file they want.

Creating an open and vast community of users brought about the possibility of web-based applications, where users could not only communicate with each other through text, but they could collaborate on work from different physical locations simultaneously.

Collaboration & Web-based Applications
Advances in HTML made it possible for the creation of web-based applications. These types of programs are primarily operated on the World Wide Web, which means users do not need to download and install a program to use it. These types of applications are regularly updated by the developer due to their online presence, and can be accessed from many common web-browsers such as Google Chrome, Mozilla Firefox, and Apple Safari. Web-based applications such as Google Docs, Apple's iCloud – and extension into Apple's Pages – make it possible to complete most productivity tasks, normally completed on computer programs, anywhere that a user has Internet access and a web-browser.
