The most important program on your computer is your web browser. And yet, most people aren't sure which web browser they're using or what a web browser even is. Let me try to explain by first telling you what a web browser is not. A web browser is different from Windows or Mac, which are systems that allow you to manage files and programs. And it's different from a search engine, which is a website that is used to search the Internet. Instead, a web browser is a program on your computer that allows you to visit websites. You get to your web browser by clicking on its icon. From there, you enter web addresses and the web browser displays the web pages for you. The web browser is the most important piece of software on your computer because every web page runs through it. So a faster web browser means that you'll save time on every web page you open. Installing a new web browser is free and only takes minutes. So take a moment to choose a web browser that you like best today.
