virtual memory is allocation of h/disk space to act as substitute RAM, is that correct ?

....is the paging file the same thing ?

how much 'space' should one allocate to the paging file...is twice the amount of system RAM correct ?

thanks

Chris

Introduction

"This page attempts to be a stand-alone description for general users of the way Virtual Memory operates in Windows XP. Other pages on this site are written mainly for Windows 98/ME (see Windows 98 & Win ME Memory Management) and, while a lot is in common, there are significant differences in Windows XP."
