Google Docs is a free, Web-based word processor, spreadsheet, presentation, form, and data storage service offered by Google. It allows users to create and edit documents online while collaborating in real-time with other users.
Google Docs is Google's "software as a service" version of an office suite. Documents, spreadsheets, forms and
presentations can be created within the application itself, imported through the web interface, or sent via email. They can also be saved to the user's computer in a variety of formats (ODF, HTML, PDF, RTF, Text, Word). By default, they are saved to the Google servers. Open documents are automatically saved to prevent data loss, and a revision history is automatically kept. Documents can be tagged and archived for organizational purposes. The service is officially supported on recent
versions of the Firefox, Internet Explorer, Safari, and Chrome browsers running on Microsoft Windows, Apple OS X, and Linux operating systems.
