15.What are web applications, and how do they work?

 

If you play online games, use an online photo editor, or frequent web-based services like Google Maps, Twitter, Amazon, YouTube or Facebook, then you’re an active resident in the wonderful world of web apps.

Web applications, also known as “apps” are programs that live on your browser or on your mobile device. They connect you to Internet services enabling you to do simple tasks, like bookmark websites and check emails. They also can do more complex tasks like share photos, navigate cities or listen to music. Your standard car navigation system is a good example of an app. Within this app, you can get real-time information based on your location. You can pan and zoom around the map, get driving directions, find alternate routes and search for specific destinations.

In addition to accessibility, web apps are actually safer. Since they run in your browser, you never have to download them to your computer, protecting you from viruses, malware and spyware. You now have much more access, and much safer access than ever before.
