What helps browsers retain the information from the pages you previously visited to make your web browsing experience faster?

The cache is essential for improving web browsing speed because it temporarily stores data from websites you've visited, such as images, scripts, and HTML files. When you revisit a site, the browser can quickly load this cached information instead of downloading it again from the internet, significantly speeding up the page load times. This mechanism reduces bandwidth usage and enhances performance, particularly for sites you frequently access.

While history tracks the sequence of web pages you've visited, and bookmarks allow you to save links for easy future access, they do not actively speed up the browsing process. Cookies, on the other hand, are small pieces of data stored by the browser to remember user preferences and actions on particular sites but don't function to retain web page data for faster loading. Thus, caching specifically serves the purpose of optimizing loading times by retaining essential content from previous visits.
