When search engine find any meaningful information on any page of our site , then it crawled our page. And when stored it temporarily to show the people then it called cached. And when this information searched by many people ,and find it useful then google stored it permanently this is called indexed.

Crawling: When the google's robot visit on a particular site then it's called crawling.
Indexing: Fetching data after crawling is called indexing.
Cashing: Taking snapshot of the website by the google is called cashing.
