As you browse the web, most page data is cached locally on your computer to help pages load faster and reduces the amount of data you need to transfer over your internet connection.

To help keep your browsing history private, and to free up disk space on your computer, you can clear your local browsing history.

If you experience strange behavior or the latest updates don't seem to work, ask your browser to empty its cache so that the reloaded page takes into account recent changes.

Your download speed represents the amount of data you can download in a given time. The rate is measured in megabits per second (Mbits/s or Mbps). Text and images (such as on a simple web page) aren’t very “heavy,” so they don’t take up a lot of bandwidth. Sound (such as the story narration in our Great Ratsby ebook series) uses more. Video can drain a lot of bandwidth, especially if you wish to ensure a good quality of image and smooth playback. A high-speed Internet connection should provide a download speed of at least 5 Mbits/s. Various Internet service providers offer rates that generally range from 2Mbits/s to 120 Mbits/s.

There are websites you can use to measure your bandwidth. For example, on http://speedtest.net, you can easily find out your download speed and see whether your current Internet connection is sufficient for good audio and video playback.
