Welcome to the community!
Your question is a very broad one but there are plenty of resources to help you familiarise yourself with AdWords and learn how it can be a benefit to your business.
I primarily suggest that you take a look at this video to get a brief run down of the idea behind AdWords and how it works. You can learn all about AdWords at the official help centre but I would recommend that you start with the setup and basics first. As you progress through the different learning material you can start checking out the resources that have been created for people studying for the Certified Partner Exams here.
The members of this community will always be happy and eager to answer any specific questions you have about AdWords and some individuals also create specified articles here.
