-sV Explanation: The "-sV" parameter is used to determine the service version of the target system. This parameter instructs Nmap to attempt to determine the version of any services running on the target system, such as the web server running on port 80 in this case. When the "-sV" parameter is used, Nmap will try to identify the service version by comparing the fingerprint of the service with a database of known fingerprints. This allows Nmap to determine the type and version number of the service running on the target system.

If additional information of the version is needed, the scan must be supplemented with a version detection scan (-sV) Module 03 Page 319 from CEH book v12

-scanVersion ;)

Guys how can it be -sV? where is the version column in the result? even if nmap was unable to find version info, it still shows a column for version information.
