electric jug

Could someone explain how americans boil water to make coffee or whatever? Like here (in NZ) I would boil an electric jug but apparently americans don’t have those? Like do you have another appliance for boiling water, or do you put it in a microwave or something. 
Related question: I said to make coffee but I just realised coffee pots are an american thing, can someone tell me what they are? Like do you put in a bunch of dehydrated granules and it heats them up with water (as if it was a giant cup of coffee)?
