Difference between 32 & 64 bit OS

can somebody help me out from this confusion what is the difference between 32 & 64 bit OS

 

The difference is 32 bits. Make sure you have a 64 bit processor and all the drivers you need or 64 bit might be a pain.

 

Hi mayur

Welcome to the best the windowsbbs!

It has to do with the largest number the CPU can handle in one bite!

Because of the use of the hexadecimal numbering system used, and "eponentiality" the number that can be addressed by 64 as opposed to 32 bit is huge.

If a 32 bit CPU has to address a larger number than it's 32 bit address space then it has to go back for another bite therefore slowing it down! If it only needs this for one or 2 bites then it will hardly be noticed. If it has to do this continually for long as in complex calculations then a great speed decrease will be noticed at 32bits.

You would think double the bite in one gulp would be twice as fast but not so unless everything the CPU does is 64bit and the majority of programs are 16 to 32 bit so it does these in one bite anyway so no speed increase.

Look and feel to you!

Filesharing and network functions noticable but not "knock your sock off "!

Normal day to day OS functions copying moving browsing etc you will see a slight difference, a large complex spreadsheet a fantastic speed boost!

An Astronomy or CAD program will greatly benifit!

Clear as Mud huh!

guitar8222 you crack me up! Did you use an Excel spread sheet to calculate that!

I jest man!

You do bring up a good point!

IF you do get for example 64 bit drivers for Video etc this will give graphics intensive programs a real boost and a percieved look and feel of day to day OS screen writes as faster.

Think of it as the difference between a two lane highway and a four lane highway. Traffic will move much smoother and faster on four lanes.

64bit makes a big difference with Virtual server as well

Hi!
I have been testing Virtual Server 2005 on many of my servers and I can tell you for a fact: If you plan on running Virtual Servers..64bit is the only way to go.

32bit has serious problems..and does not work as well. I point out it is no surprise that Hyper-V only runs on 64bit 2008 servers.
