A miner is a piece of hardware that solves SHA-256 hashes (in the case of bitcoin) or scrypt, quark and others, in the case of other coins.

And generating hashes is DEFINITELY NOT SIMPLE.

You can search WIKI in your language..

Anyway yes - for a computer solving SHA256 is a quite big job. That's why such Hashrates are needed.
