This thread is full of theoretical stuff, lot of useful info but nowadays I only deal with practical reality.
That is the single biggest problem with the people I meet here in LUG. You have to get practical doubts. Theory is fine but we have to grow beyond that. I have worked on few embedded systems but swap has never been a doubt in my mind. As Raja said MMU is the issue. Without MMU there is no memory management, no paging and so no swap. Even desktops can work without swap with adequate RAM. -Girish On Wed, Mar 28, 2012 at 2:43 PM, Arun Venkataswamy <arun...@gmail.com> wrote: > On Wed, Mar 28, 2012 at 12:41 PM, Ganesh Kumar <bugcy...@gmail.com> wrote: > >> I am asking silly doubt.
