When you visit a website, your browser (e.g., Chrome, Firefox) downloads and stores cookies, which are small files containing information about your activity and preferences for that website. This allows your preferences to be easily retrieved next time you visit that website (e.g., sort order on a browse page).

When you visit a website, your browser can save the pages you visit in your browser's cache. The website will load faster the next time you visit it because the browser already has the webpages saved from the first visit. However, this means that if a website has been updated since last visit, your browser may be showing you old webpages from its cache instead of the updated pages. Therefore, it's recommended to periodically clear your browser's cache.
