Crawler, Indexer and Query in Search?

There are 3 major concepts of SharePoint 2010 search and they are Crawler, Indexer and Query.

Crawler: This component browses the contents automatically on a regular basis. so that indexer will get the updated data every time.
Indexer: This component is responsible for collecting and storing relevant data of crawled contents, in order to make available fast and precise information retrieval during the queries.

Query: The Query component provides the UI for entering the user queries, and presents the result set to the end users. It communicates with the Indexer component directly to get the results for the user query, and to put the proper result set together.
