What distinguishes a search engine from a directory?

• A. Directories are faster
• B. Search engines crawl the web with spiders
• C. Directories require user submissions
• D. Search engines index manually curated websites

Answer: (B)

The correct answer highlights a fundamental characteristic of search engines: they utilize automated programs known as spiders or crawlers to explore the web and gather data. These spiders follow links on web pages to index the content they find, allowing the search engine to provide relevant results to user queries based on a vast amount of indexed information from across the internet. In contrast, a directory typically relies on human effort to compile and categorize websites, which means that it does not automatically discover new pages or content as a search engine would. This distinction is crucial because it impacts how quickly and comprehensively users can find information online. Search engines can provide a wider range of results more quickly because their spiders continuously crawl the web and update their indexes, while directories may have outdated information if sites have not been submitted or reviewed recently.
