32-bit OS can only hold up to 4GB of memory. 64-bit OS can hold up to 1TB of memory, most motherboards can only hold from 12 to 16GB of memory.
a 32-bit OS is limited to 4 Gigabytes of ram
A 32-bit OS can only address up to 4GB of memory.
32-bit OS has many limitations. It can not use full 4 GB RAM or more that that. It can utilize only 3.7 GB of RAM.
For the 32-bit Windows 7 operating system, the RAM (random access memory) limit is set at 4GB. The 64-bit OS, however, has more flexibility in terms of RAM capacity.
no
No, this is how it works. 64-bit CPU - 64-bit OS - 64-bit Program = Yes 64-bit CPU - 32-bit OS - 64-bit Program = No 64-bit CPU - 64-bit OS - 32-bit Program = Yes 32-bit CPU - 64-bit OS - 32-bit Program = No So, basically, the 64-bit CPU just means that it can support an OS up to 64-bits. But whatever OS you install is the deciding factor. So, a 64-bit program will not work on a 32-bit OS, even if there is a 64-bit processor, although a 32-bit program will run on a 64-bit OS. Hope this helped! SeanHolshouser
All 64 bit versions of the OS's.
yes
There are two versions, one for 32 and second for 64 bit. If your version is for 32 bit, it will not work in 64 bit computer.
32 bit is what most users come across, its typically used with smaller amounts of memory especially in windows since XP maxes out at roughly 3.3gb of system memory this is due to its 32 bit instruction set. A 64 bit application is designed to run on a 64 bit instruction set operating system (OS). This is better since a 64 bit instruction set will process roughly 4 times the instruction set of a 32 bit instruction set a 64 bit OS is faster at computing data. Also the memory architecture does not max out at 4gb the way 32 bit does, it maxes out at 128gb. Most systems cannot handle this and very few need these types of memory bandwidth. 64 bit was originally introduced for a short time as Windows XP 64-bit edition. It was bug ridden and barely saw the light of day and has software compatibility issues with just about everything. Once Vista came out they also standardized the release of a 64bit OS, Thus Home Premium 64 bit and Ultimate 64 bit. Now windows 7 has a similar setup. Typically if your machine is within 2 years old and has 4gb of ram or more it probably came with a 64 bit OS. However it can run 32-bit just fine. So safe bet is to download the 32bit application because you more than likely wont notice any speed improvement with a 64 bit application and it wont run on a 32 bit OS so check your system in windows by going start/(right click)My computer/properties and look for 32-bit or 64bit if it is windows Vista or 7, if its XP its a safe bet you have a 32 bit as you have to purposely install 64 bit XP it did not come standard on any consumer PC that I am aware of.
Generally No!
