64-bit computing, who's familiar with this one?

i'm not familiar with this one, but is this good news? or what...

**poldopunk** · 08-28-2008, 10:16 AM

its good, and its been around a while. in fact:

are our current pc using this 64-bit processors? daku ba jud ni sya requirements when it comes to hardwares (like RAM)?

practically, this is really a good news.... compared sa 32-bit technology... hardware problem only for those obsolete... pero kanang mga bag o karon, they are designed for compatibility....

yup, its been on the desktop world since 2003. when Athlon 64 was released..
then shortly intel actually followed AMD on this one.. although earlier, intel created itanium with 64-bit instructions, its not desktop x86 processor

main advantage is the maximum memory you can use. 4Gb for 32-bit cpus (=2^32)
and (=2^64) thats 18,446,744,073,709,551,616 bytes for 64-bit

with regards to speed, it depends, since 64-bit programs have larger execution overhead/larger memory requirement than 32-bit programs thats why many 32-bit apps are faster than their 64-bit counterpart.

anyway, 64-bit processors are not uncommon even during 90s with the UNIX workstations...

so you need 4G RAM for this.. that's a lot of RAM..
considering my PC has only 1G RAM..

nope. you dont need 4G
when you want to have a 64-bit system
you need:
64-bit OS and a 64-bit processor. (windws x64 pro, or windows vista 64-bit editions, various 64-bit linux)
it doesn't matter how much is you ram... as long as there is ram

okey.. so with regards to software, dili ni sya makaaffect?

most modern software wala naman na problemaha. the reason nganu ang uban muingon nga you need 4GB ram or more is a misconception, but rather the limit of 32 bit systems is 3GB+ram, so if you need 4GB+ than that the only solution is 64bit.

it means that you can go higher than 4GB as compared to 32-bit systems where the limit is 4GB but the OS (Windows 32-bit) only can only use 3.5GB as the other .5 is reserved for your devices.
