title: Is Virtual Memory still relevant in today's world of inexpensive RAM?
body: <p>Virtual memory was introduced to help run more programs with limited memory. But in todays  environment of inexpensive RAM, is it still relevant?</p>
  
  <p>Since there will be no disk access if it is disabled and all the programs will be memory resident, will it not improve the performance and program response times?</p>
  
  <p>Is there any essential requirement for virtual memory in windows apart from running more programs as stated above? Something windows internal not known to us.</p>
