This question was addressed to me in an internship interview.
This key question is from Compressing and Archiving Files in chapter Handling Ordinary Files of Unix
To explain I would say: To create an archive -c option is used, -v is used to display the progress while tar works while -f is used to specify the name of the archive. All these options can be combined together as (-cvf).
