12 May Open Web vs. Deep Web

The internet has been inhabited by protocols for browsers to read content in HTML (HyperText Markup Language) that create a massive web of interconnected content collectively known as the “world-wide web” (www) or just the “web”. The open part is content that is not protected by passwords, and thus accessible to anyone. Some pages on the open web do not permit search-engine access for crawling and indexing, thus making the content harder to find, but nevertheless accessible.

TechTarget tells us that “Deep Web content includes information in private databases that are accessible over the Internet but not intended to be crawled by search engines. For example, some universities, government agencies and other organizations maintain databases of information that were not created for general public access. Other sites may restrict database access to members or subscribers.” (definition: deep web)
