Connect a laptop computer to a GPS, and use it for navigation?

What kind of GPS does one need, what computer software does one
install on the laptop, and how do you use the laptop to plot
your location, and where you want to go?

I am very interested in learning how to do this, and in getting
all of the things to be able to do it!

Thank you
