one tablet to multiple PCs

 one tablet to multiple PCs

My wife has an asus (android) tablet and has successfully linked it to her vaio laptop. i tried to add an account on the tablet so we could alternately look at my computer (toshiba laptop). was able to start adding an additional connection and got to the "host address" and "password" blanks which need filling. unsure what i need to put here, and/or where to find this info on my laptop.
thanks,
gene
