There are two kinds of penalties you can receive: algorithmic and manual.

Algorithmic means that your website conflicts with Google’s search engine algorithm wholly or partially.

A manual penalty arises when you’ve been engaging in a bad SEO activity that is against Google’s terms of service and somebody intimates Google about it. Examples include selling links on your site, inclusion of sneaky hidden text etc.
