Therefore, a number of applications for which the fixed-line Internet is widely used have been adapted for mobile environments. Web browsing is certainly the most popular Internet application. It benefits from a fast connection and depends on the reliability of the bearer, especially if web pages are big and thus take some time to be transferred, during which no transfer interruptions should occur.
