I am going to be buying a extrenal hard drive soon, but I do have a few questions about it. I play alot of PC games, my questions is can I install all my games on the external hard drive or do they have to be installed on the internal drive where the operating system is installed. Also gonna be getting a laptop soon I want to be able to have the desktop and laptop to be able to share the same internet connection how do i go about doing that. Also I want the laptop be to use the same printer as my destop computer. How to i go about doing this. Do I have to buy a router to do this.
