Reloading data refers to downloading browser content that has already been partially or completely displayed. A data reload ensures that the most recently updated information on a Web page or application is shown.
Data reloading is also referred to as data refreshing since refreshing a page or a window reloads it with fresh information. When used with a Web browser, reloading retrieves the current version of the page, and in some cases, recently published changes to the page. Reloading or refreshing a window displays a current list of files. The shortcut key to reload a page in Windows is F5, while the Command-R function is used on a Mac.
