Web browsers are programs that “read” hypertext and display it as formatted text and images. Browsers allow users to view the contents of a site and navigate from one site to another. Increasingly, these browsers also employee scripting to create full-featured, dynamic, and interactive web applications. Web browsers have become the dominant user interface today.
Mobile client web browsers are browsers embedded in or downloaded to cell phones or smart phones. Internet/Extranet mobile client web browsers are used by external NIH stakeholders (grantees, researchers, patients, practitioners, etc.) to gain access to NIH’s public Internet resources or extranet applications via the mobile Web. Because NIH has very little control over what mobile client or mobile browser public or extranet users will use, content managers and web developers that support public-facing websites or extranet applications must develop and test for a wider variety of browsers.
