Several of us, including myself, have pointed you to places on the internet where you can get basic information. Have you used those links? If I asked you in a classroom, what does f-stop have to do with depth of field, could you give me the answer? If not, then you need to do your "homework". Study each element (exposure, depth of field, etc.) by itself and start shooting and posting your own photos WITH exif data and let us critique or provide you feedback.
You're not going to become a photographer "overnight", regardless of how "smart" your camera is. We are all happy to help you, but you need to do your homework first and SHOW us something that you've done. There is NO CANNED answer to what you're asking. Unless you learn the basics, you're just spinning your wheels. So, get out there, shoot photos, look at your settings, and post the photos that YOU shot and that you have questions about.
