While reviewing HTML code in a web page, you discover a tiny element that loads a resource from a remote server to report when the page is viewed. What is this element most commonly called?

• A. Web bug
• B. CGI code
• C. Trojan.downloader
• D. Blind bug

Answer: (A)

A web bug is a tiny element embedded in a web page that, when loaded, causes a request to a remote server to report that the page was viewed. It’s typically a 1x1 pixel image (or a small beacon) whose source points to another domain, so simply loading the page reveals that someone viewed it. This is used for tracking and often operates invisibly to the user. The other options don’t fit this behavior: CGI code is server-side code that runs on the web server, a Trojan.downloader is malware designed to fetch more payloads, and a blind bug isn’t a recognized term for this mechanism. So the described element is a web bug.
