What are files called that store users' browsing history on their local computers?

Files that store users' browsing history on their local computers are referred to as cookies. However, cookies primarily serve as small pieces of data that websites use to remember information about users for various purposes, such as maintaining user sessions and preferences. They do play a role in tracking users’ activities and can store information about browsing sessions, but they may not be strictly defined as the history of all visited sites.

Among the other options, cache refers to temporary storage of web pages and content to speed up loading times; sessions pertain to a user's ongoing interaction with a website during a specific time; while history logs explicitly record the browsing history itself. These terms highlight different facets of how web data is stored or utilized, but cookies are often the most recognized method of data storage related to user interactions on the web.

Thus, while cookies play a role in tracking sessions and user preferences, history logs more accurately reflect the comprehensive record of pages visited, suggesting that term more directly relates to the concept of browsing history. The answer given would need adjustment for ultimate clarity with respect to the question asked.
