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.
Office Online
Office Online (known before 2014 as Office Web Apps) is an online office suite offered by Microsoft, which allows users to create and edit files using lightweight Microsoft Office web apps: Word, Excel, PowerPoint and OneNote. The offering also includes Outlook.com, People, Calendar and OneDrive, all of which are accessible from a unified app switcher. Users can install the on-premises version of this service, called Office Web Apps Server, in private clouds in conjunction with SharePoint, Microsoft Exchange Server and Microsoft Lync Server.
