Google Docs, Google Sheets and Google Slides are a word processor, a spreadsheet and a presentation program respectively. The three programs originate from company acquisitions in 2006, and are today integrated into Google Drive as part of the Google Docs suite. They all serve as collaborative software that allow users to view and edit documents, spreadsheets and presentations together in real-time through a web browser or mobile device. Changes are saved automatically, with a revision history keeping track of changes. There is also the capability to set user permission levels to designate who can view, comment or edit the document as well as permissions to download the specific document. Google Forms, meanwhile, is a tool that allows collecting information from users via a personalized survey or quiz. The information is then collected and automatically connected to a spreadsheet. The spreadsheet is populated with the survey and quiz responses.
