My Mac Mini can be hacked from the Wifi?

Hello!

I was a proud owner of Mac Mini, less than a week. First of all, I would like to give my gratitude to Apple for creating this wonderful little tool.

But as a long time Windows user, I ran into a problem I can't seem to find an answer to.

I discovered that my Mac had opened a Wifi connection. And as a person, which is used for cables Ethernet (that I use now, too), the Wifi is unknown and not very liked territory.

Was on WiFi, but marked "wifi is turned on, but is not connected to a network.

N00b I am, am a little worried about this new link, began to bite it and found a lot of names, I understand where my neighbors Wifi connections. With my luck, I managed to hurt someone, who do not have their protected Wifi password and found myself suddenly watching "wifi is connected to the android ap and a IP [...]".

I panicked as *, started trying to find a way to get rid of it and seemed finally to delete it after 3 minutes of the curse.

Then, I turned off the wifi and changed to 'inactive' as well.

My apologizes for the long text, but I'd love to hear the opinions of people who are not filled with panic as I am:

1) when "wifi is turned on, but is not connected to a network", it means it is secure and no one can hack my wifi Mac?

(2) when I entered accidentally someone another wifi unprotected for a few minutes, my Mac have been compromised?

And the most important:

(3) Changing wifi to be 'off' and then 'dormant', am I sure of any wifi hacking back? As there is zero connection wifi and no one outside could enforce on my Mac?

I understand how stupid my questions can and no doubt make sound, but I'm inherently paranoid person and only one in my family, which has a semblance of agreement when it comes to computers, so there is no one to ask.

I would be very grateful if someone could help me,

Sincerely

(1) Yes

(2) No, just don't send any important information on an unprotected WiFi (passwords, credit card numbers etc.)

(3) Yes
