Kyle, there has to be some thinking behind those settings. Tim Campbell did his usual excellent description. But before you get too far, let's have a discussion.
If someone suggests that ISO 800 is good for a sunny day, your first question should probably be "Why?" Followed by the second question of "what's my base ISO?" (answered by referring to the manual), and followed by the third: "Why would I need to change from base ISO to 800? What will that allow me to do that I can't do otherwise?".
Your settings are 5 stops overexposed according the the sunny 16 rule. By coincidence, your exposure compensation setting of -5 essentially biases the meter by the same amount.
Perhaps you can help us understand by your describing the reasons for the settings that your camera was set to.
