Explanation:
Understanding Office Web Apps (Installed on SharePoint 2010 Products)
Microsoft Office Web Apps is the online companion to Office Word, Excel, PowerPoint and OneNote applications that enables users regardless of their location to access documents and edit documents. Users can view, share, and work on documents with others online across personal computers, mobile phones, and the Web. Office Web Apps is available to users through Windows Live and to business customers with Microsoft Office 2010 volume licensing and document management solutions based on Microsoft SharePoint 2010 Products.Integration with SharePoint 2010 Products
Office Web Apps is tightly integrated with SharePoint 2010 Products. When you install Office Web Apps, the Office Web Apps Services are added to the list of SharePoint Services and the Office Web Apps Feature is added to the available SharePoint Features.
Office Web Apps services include the Word Viewing Service, PowerPoint Service, and Excel Calculation Services that are created and run within the context of SharePoint Services.
The Office Web Apps Feature and services integrate with SharePoint’s robust enterprise content management capabilities to provide users the ability to access and work on your organization’s documents from anywhere using a Web browser.Understanding the Office Web Apps user experience
Viewing and editing Office documents
Office Web Apps gives users a browser-based viewing and editing experience by providing a representation of an Office document in the browser. When a user clicks on a document stored in a SharePoint document library, the document opens directly in the browser. The document appears in the browser similar to how it appears in the Office client application. The Web app also provides many of the same editing features as an Office client application.
Office Web Apps provides this representation of an Office Word document, PowerPoint presentation, Excel workbook, or OneNote notebook using native browser objects such as HTML, JavaScript, and images. Each document type is handled differently depending on the Office Web Apps services started and whether the Office Web Apps Feature is activated.
A document in the Word Web App, PowerPoint Web App, or Excel Web App can be edited in the browser or can be opened for editing in the associated Office client application. If while viewing or working in a Web app a user clicks the Edit in Browser button on the Home tab of the toolbar, the user can perform light editing tasks in the browser. A notebook in the OneNote Web App can be edited in the browser natively without having to click the Edit in Browser button or it can be opened for editing in the OneNote client application by clicking Open in OneNote.
If while in a Web app a user clicks the Open in Word, Open in PowerPoint, Open in Excel, or Open in OneNote button on the toolbar, the document will open in the associated Office client application if it is installed on the client computer.Improving the user experience with Silverlight
Silverlight is a free plugin that can provide richer Web experiences for many browsers. The Silverlight plugin is not required to be installed on the client browser to use Office Web Apps. However, having the Silverlight plugin installed on the browser can provide the following benefits:
* When using the Word Web App on browsers with the Silverlight plugin installed, users can experience faster page loading, improved text fidelity at full zoom, ClearType tuner settings support, and improved accuracy in location of search string instances when using the find on this page feature.
* When using the PowerPoint Web App on browsers with the Silverlight plugin installed, users can experience faster page loading, animations will appear smoother than without, and presentation slides will scale with the browser window size.Having Silverlight installed on the client browser does not provide any additional benefits in Excel Web App and OneNote Web App.
