Web browsers
A web browser is the tool you use to access the Web. The browser's main job is to display webpages. It also lets you create bookmarks—sometimes called Favorites—for sites you like so you can easily find them again later.
The World Wide Web is a virtual network of websites connected by hyperlinks (or links). Websites are stored on servers on the Internet, so the World Wide Web is a part of the Internet.
Your computer probably came with a browser pre-installed. PCs come with Internet Explorer, while Macs come with Safari. If you prefer to use a different browser, you can download Firefox, Google Chrome, or Opera. All of these browsers are free.
