I know very little about computer systems i know hardware is the physical parts of the computer and the soft ware is the discs installed into the computer. i have seen the inside of a computer about three times in my life and the last time the part were explained to me was in grade 1 at cub scouts. i know a network is your feed to the internet but i don't know how to set one up besides plugging one into the computer. and i know that i use windows and it works ok not great but ok.
