Break down the components of a URL and explain what each part means.

• A. Scheme (http/https), host/domain, optional port, path, query, and fragment; together locate and describe the resource.
• B. Host only.
• C. Path only.
• D. Query only.

Answer: (A)

A URL is built from several pieces that work together to locate a resource and describe how to access it. The scheme tells the browser which protocol to use, such as http or https, and indicates how the data will be transmitted, including whether the connection is encrypted. The host or domain names the server where the resource lives, and DNS translates that name to an IP address so the browser knows where to reach. If present, the optional port comes after the host, preceded by a colon, and it overrides the default port for the chosen scheme (for example, 80 for http or 443 for https). The path specifies the exact location on the server, usually reflecting a directory structure and starting with a slash. The query begins with a question mark and carries parameters in key=value pairs, often used to tailor what the server returns (multiple pairs are separated by ampersands). The fragment starts with a hash and points to a specific part within the loaded document, used by the browser to navigate to that portion and is typically not sent to the server. Together, these parts locate the resource and describe how to retrieve and interpret it.
