Don't over think it to much. Take a look at the example above.

AND and OR behave the same in both fields and queries.  You are just testing two qualities against each other to get a result.

BTW - Ignore the XOR for now.

XOR has a great real-life application.  If two light switches control the same light bulb, and you want the light to go on or off whenever EITHER switch is flipped, then you need XOR logic for the two switches.

When both switches are off, you flip one of them to on to turn on the light.  Then you go to the other switch, flip it to on also, and it turns OFF the light.  You go back to the first switch (which is on), flip it to off, and it turns ON the light.  Flip the switch "on" again, and the light is off.  Note that when both switches are "on" or both switches are "off", the light is OFF.  That is the tell-tale sign of XOR logic at work.

Kevin we weren't asked about XOR nor is it relevant to what Heidi asked.
In addition XOR has only been briefly been covered.  It doesn't do much to help people out when the answer is way above the skill level they are learning at the moment.

Sometimes you need to mention a few interesting asides to stroke the students' interest.  If a common electrician needs to know about XOR, then it's not above most students' skill level.

I have NNNOOOOO idea about this XOR. If I did, I am sure what you said Kevin would make a lot of since, however, I was very lost in that. I think Scott hit this one- so what I understand is that they serve the same purpose correct? I am currently building this for my business and really need to make sure I do this right, so I won't run into a ton of errors later. As I am so new to all of this, I feel I am getting it rather quickly. Just like I said wanted to make sure before I really start putting in the data, I need in it. Thank You both for the Kevin I am sure at some point I will understand this whole light switch thing but as of now, I am fine with however my lights turn on!! ;)
