NLS 'resource sharing' was based around the mainframe. So essentially, NLS didn`t have resource sharing since it was just one machine (i.e., it`s all shared). Alto had the idea of sharing via the network (i.e., printer server).

	Alto focused a lot less on 'hypertext' and less on navigating deep information. It was designed around the idea of paper. It implemented existing metaphors and adapted them to the PC. Alto people came from a culture that really valued printed paper. It is important and interesting to make a note of technology that falls away or becomes obsolete.
