Google Docs, Google Sheets and Google Slides are a word processor, a spreadsheet and a presentation program respectively, all part of a free, web-based software office suite offered by Google within its Google Drive service. The suite allows users to create and edit documents online while collaborating with other users in real-time. The three apps are available as web applications, as Chrome apps that work offline, and as mobile apps for Android and iOS. The apps are compatible with Microsoft Office file formats. The suite also consists of Google Forms (survey software), Google Drawings (diagramming software) and Google Fusion Tables (database manager; experimental). While Forms and Tables are only available as web applications, Drawings is also available as a Chrome app. The suite is tightly integrated with Google Drive.〔(【引用サイトリンク】title=Google Drive )〕 All files created with the apps are by default saved to Google Drive. ==History== Google Docs originated from two separate products, Writely and Google Spreadsheets. Writely was a web-based word processor created by the software company Upstartle and launched in August 2005. It began as an experiment by programmers Sam Schillace, Steve Newman and Claudia Carpenter, trying out the then-new Ajax technology and the "content editable" function in browsers.〔(【引用サイトリンク】title=Google Docs began as a hacked together experiment, says creator )〕 Writely's original features included a collaborative text editing suite and access controls. Menus, keyboard shortcuts, and dialog boxes are similar to what users may expect in a desktop word processor such as Microsoft Word or LibreOffice Writer. Google Spreadsheets, first launched as a limited test on Google Labs on June 6, 2006,〔(【引用サイトリンク】title=Google Press Center: Google Announces limited test on Google Labs: Google Spreadsheets )〕 originated from the product XL2Web by 2Web Technologies, which was acquired by Google in June 2005. On March 9, 2006, Google announced that it had acquired Upstartle. At the time of acquisition, Upstartle had four employees. Writely closed registration to its service until the move to Google servers was complete.〔 In August 2006, Writely sent account invitations to everyone who had requested to be placed on a waiting list, and then became publicly available on August 23. Writely continued to maintain its own user system until September 19, 2006, when it was integrated with Google Accounts.〔(【引用サイトリンク】title=The Writely Blog: Google Account Sign-in LIVE )〕 Writely originally ran on Microsoft ASP.NET technology which uses Microsoft Windows. Since July 2006, Writely servers appear to be running a Linux-based operating system. Meanwhile, Google developed Google Spreadsheets using the technology it had acquired from 2Web Technologies in 2005 and launched Google Labs Spreadsheets〔〔(【引用サイトリンク】title=Its Nice to Share )〕 on June 6, 2006, as the first public component of what would eventually become Google Docs. It was initially made available to only a limited number of users, on a first-come, first-served basis. The limited test was later replaced with a beta version available to all Google Account holders, around the same time as a press release was issued. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Google Docs, Sheets, and Slides」の詳細全文を読む スポンサード リンク
