What are the two search services mentioned in the guide?

What do they both give us?

Can you set some examples of search engines?

Answers:

Search engines and subject directories.

They both give us direct links.

Google, Yahoo, Lycos and Excite.

Search engines are a type of computer program.

Search engines present evaluated contents because the information has been checked by a person.
