Learning how to create a bookmark or add to favorites is a very wise thing. This is especially true if you use the Internet for any of the reasons described below. These are not the only reasons why knowing how to do this is important, but they are the most common ones.
When you add to favorites, you always have those bookmarks, at least until you decide to delete them. Say you are shopping online and you find something really cool to buy, but you still want to look around on other websites for the same product at a better price or with better features. All you do is bookmark this page, essentially saving it, and then go to other websites until you find what you are looking for. Then you can refer back to the bookmarked page when you have shopped around enough.
