Microsoft Office
Microsoft Office is a family of client software, server software, and services developed by Microsoft. It was first announced by Bill Gates on August 1, 1988, at COMDEX in Las Vegas. Initially a marketing term for an office suite (bundled set of productivity applications), the first version of Office contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, OLE data integration and Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. On July 10, 2012, Softpedia reported that Office is used by over a billion people worldwide.
OneDrive
Microsoft Office, starting with Microsoft Office 2010 and Microsoft Office for Mac 2011, allows users to directly open or save documents to OneDrive, or simultaneously edit shared documents with other users. Changes are synchronized when a document is saved and, where conflicts occur, the saving user can choose which version to keep; users can also use several different desktop and web programs to edit the same shared document.
