What best describes the deep web?

• A. Part of WWW not discoverable by standard search engines
• B. Portion of WWW readily searchable
• C. Part of WWW accessible only by special software
• D. A private intranet

Answer: (A)

The deep web consists of parts of the World Wide Web that standard search engines don’t index or easily reach. This includes databases, behind-login portals, dynamic pages that only appear after submitting a query, and other content that isn’t surfaced by crawlers. Because search engines rely on indexing and following links, anything that requires credentials, forms, or on-demand generation tends to stay out of their results. That’s why the best description is that it’s a portion of the WWW not discoverable by standard search engines. It’s not simply “readily searchable,” nor is it defined strictly as content accessible only with special software—that latter idea points more to the dark web, a subset of the deep web. A private intranet is separate from the public web and isn’t what the deep web refers to.
