Google Applications
Google Apps is a collection of web-based programs and file storage that run in a web browser. The applications include communication tools (Gmail, Google Talk, and Google Calendar), productivity tools (Google Docs: text files, spreadsheets, and presentations), a customizable start page (iGoogle), and Google Sites (to develop web pages). Google stores all of the files and content centrally and keeps a record of the different versions of a file. With Google Apps, sharing content is as simple as granting someone access, which facilitates collaboration, peer review of academic materials, and the collective generation of knowledge.

Use these briefs for a no-jargon, quick overview of a topic and share them with time-pressed colleagues. (Source:
