A web browser is a program installed on your computer that let's you access and surf the internet. It is the thing that let's you see websites. Internet Explorer for Windows is an example.
Why do I need multiple web browsers?
Having multiple web browsers creates a back-up or alternate way of accessing the internet if the one you use decides to stop working or crash. Sometimes, you may even encounter a virus that may block a particular web browser, but not another one. Also, some websites may not be compatible and this provides a more effient way of getting to your favorite website. Web browsers wear out, become corrupt, out dated and break, just like other computer programs. Upgrading the web browser version or completely re-installing the browser program usually corrects the glitch. But, this isn’t effective when time is not on your side. Using a backup web browser to access information on the Internet will save time and headaches until the problem can be fixed.
