You haven't said what OS you are using (no signature information either), so it really isn't possible to say what the windows firewall is going to do.
You actually learn by doing (the searches as suggested), that sticks in the mind, searching for the XP/win7/win8.0/win10 firewall would give you relevant information.
Simply asking questions like this if given answers will soon be gone from memory and end up being asked again.
Add to that, you shouldn't be surfing but working while you are at work.
Set aside some time when you are at home to use the links that both Pondus and Eddy have kindly provided. Learn what you need to know.
