What is the primary purpose of using a web cache?

Using a web cache primarily serves to enhance browsing speed by saving files. When you visit a website, various elements such as images, CSS stylesheets, and JavaScript files are downloaded from the internet to your device. A web cache temporarily stores these files so that when you revisit the same website, your browser can display the page faster by retrieving these cached files from local storage instead of downloading them again from the web. This process reduces load times, conserves bandwidth, and improves the overall user experience while browsing.

The other options do not reflect the primary function of a web cache. For example, while archived web pages can offer historical records of web content, they are not the main purpose of caching. Similarly, maintaining security protocols is essential for safe browsing but does not correlate directly with the caching process's primary intent. Storing all data types is also inaccurate, as a web cache specifically optimizes certain web content to enhance speed rather than acting as a general storage system.
