How Search Engines Work?

Search engines surf the web with the help of spiders.Spiders look for documents and their web addresses.Documents and their respective web addresses are collected which are then sent to search engines software for indexing.The software then extracts the information from those documents and stores them in its database.
When a user searches a query in the search box,then the database is searched for relevant results which are then collected and are displayed as links.

What is a Directory?

Directory is collection of website addresses,each of which organized in some category and each category into subcategory.Directory is almost similar to search engines but here human beings are involved who maintain and update the information.Results in a directory are taken from websites that have been submitted to it.
