What are cookies in web terms?

• A. Small text files saved on a computer's hard drive by a website.
• B. Web cookies are small text files stored on your device by a site.
• C. They are executable programs that run in the browser.
• D. They are settings stored in the browser's memory only.

Answer: (B)

Cookies are a small data payload a website can store on your device through the browser, so the site can remember information across visits. They’re typically plain text data saved on disk and sent back to the site with each request, which lets the site recall things like your login status, language or site preferences, and items in a shopping cart. They’re not executable programs, nor are they merely settings that exist only in memory; many cookies persist beyond a single session by living on disk. That combination of being small text data stored by a site on your device and sent with requests is why this description is the most accurate.
