GPS navigation

Today in class, we took notes on the GPS which gives you directions on how to get somewhere. but we also learned that when we put the location of your home and its address, hackers could find that and go to your home. When you put an address and place into a GPS it gives you precise coordinates of the place. Then we talked about alexa and how dangerous it could be. It could be very bad because when you say its name, it responds to you because it is listening to for its name meaning that it hears everything you say. If someone wanted to listen to you,they could hack in to alexa and hear conversations and possibly figure out when you are and aren't home so they could brake in.
