What is the difference between Nofollow and No-indexing?

[RH-Calvin]

No index, no follow implies that the search engine robots do not crawl the particular link or webpage. This ensures that the webpage or the link is never indexed in Google. No follow is a link attribute that instructs spiders not to crawl the particular backlink on the webpage. Hence these links are never indexed in search engines. They are only used to build traffic from various external webpages.
