Linux gives You access to more Physical Memory than is present

linux OS gives u access to Physical memory*2 memory space;

to illustrate this just run following codeĀ  in your linux OS.


now try this code, just little changes i already have made.


i hope u have understood how does linux gives u access to physical memory more than u really have.

in memory2.c instead of allocating size in MB, I have allocated size in terms of GB.

run the code to understand how does it actually works.
