Browser is a software that allows the user to access the world wide web. Each web page, image and video has its own Uniform Resource Locator (URL), allowing browsers to download these resources from a web server and show them on the user’s device.
Web browsers on smatphones may be capable of viewing only websites specially made for mobile devices. The most advanced devices currently have web browsers. They come with full Flash support that allows them to play even embedded Flash video (like the videos from YouTube).
