Web browsers store information to speed up future visits in what type of storage?

Web browsers use cache storage to enhance user experience by storing copies of frequently accessed web content, such as images, HTML files, and scripts. When a user revisits a website, the browser can quickly retrieve the cached data instead of downloading all the content again, which reduces loading times and saves bandwidth. This temporary storage is specifically designed to hold this type of frequently used data and enables the browser to operate more efficiently.

This is distinct from other types of storage mentioned in the question. Backup storage refers to data that is saved for recovery purposes and does not aid in speeding up the browsing experience. Memory (or RAM) is used for temporary active processes but does not retain information after the browser is closed. The hard drive is a form of long-term storage where all types of data may be saved, but it functions differently from cache, which is designed specifically for rapid access to web resources.
