An internet track is simply a work file created by your browser or email program when you use the internet. These files are used by your browser to make browsing faster or more convenient. For example, your Browser History function allows you to easily revisit a page you've already been to by displaying a list of URLs that you've been to recently. This may be convenient for you, but may be embarrassing if you share a computer with your teenaged children and have been surfing sites for solutions to your hemorrhoid problem. There are many types of internet tracks created when you go on the internet, depending on the browser you are using, including: - browser cache, browser history, favicons created when you browse site - download cache created when you download files from other sites
