    I read an article in UNIX World comparing system V and AIX. It clearly
stated that System V did not have VM(Virtual Memory concept). Can someone
clear the following doubts for me through e-mail to nataraj@happy.cc.utexas.edu


   (1) If there is no VM, how does the operating system, bring the programs
from secondary storage to main for execution.(System V )

   (2) How does MS-Dos solve the above problem?
    
    (3) I have comments like Unix needs at least 4M of main memory?
      Is it for all the daemons to run?

      Thank you
