Google Apps is a overhaul from Google for using custom domain names with several Google products. It features several Web appliances with similar functionality to customary office suites as well as Gmail, Google Calendar, Talk, Docs and Sites.

Google Apps is a group of web-based programs and file storage that run in a web browser. The applications include message tools like Gmail, Google Talk, and Google Calendar, productivity tools like Google Docs : text files, spreadsheets, and presentations, a customizable start page (iGoogle), and Google Sites. 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.
