Do You Know How Much Ram Can 64 bit Computing Supports

Once I went searching Google that how Much memory Windows 7 64 bit computer supports and i was amazed by the fact that it supports 128GB Ram on its Windows 7 professional version. But today From a Dell engineer i got a link to The apple website which tells us it can address a theoretical 16 billion gigabytes of memory which is 16 Exabyte.


The Apple websites says “The entire computing industry is moving from 32-bit to 64-bit technology, and it’s easy to see why. Today’s Mac computers can hold up to 32GB of physical memory, but the 32-bit applications that run on them can address only 4GB of RAM at a time. 64-bit computing shatters that barrier by enabling applications to address a theoretical 16 billion gigabytes of memory, or 16 Exabyte. It can also enable computers to crunch twice the data per clock cycle, which can dramatically speed up numeric calculations and other tasks. Earlier versions of Mac OS X have offered a range of 64-bit capabilities. Now Snow Leopard takes the next step in the transition from 32-bit to 64-bit.”
