If you wondering what is meant by x32 x64 x86 operating system?
The answer is x86 should not be confused with 32 bit and 64 bit. For x86, read up here: http://en.wikipedia.org/wiki/X86 As for the difference between 32 bit and 64 bit, this has to do with the amount of memory the system is able to allocate to keep it very simple.
32 Bit operating systems can allocate up to 4 GB of memory (where only around 3,5 GB will be really useable) and 64 bit operating systems can allocate more than 4GB of memory. If you use less than 4 GB of memory, then use a 32-bit operating system as it will work faster than a 64-bit operating system. If you use more than 4 GB of RAM, then use a 64-bit operating system as it will work faster than a 32-bit operating system.
Long story short, X86 was the first designed architecture for computer processors and could only hold up to 4 GB of RAM ( 3.84GB more exactly ), 64bit ( or x64 ) was developed with the rise of Athlon 64 CPUs, which could stand up to more than 4 GB ram ,and support new technologies 😀 . I think
Isn’t it like that? If CPU process 64-bit memory its called 64bit?
If the CPU has x64 instructions you’ll see the computer recognizing him as a x64based processor and works with both 32bit programs and 64bit
X64 is the Processor’s designed architecture such as X86.
CPUs designed with x86 architecture work with 32bit programs and DO NOT work with 64bit ones as it can’t handle the extra workload and it was a technology that appeared AFTER the launch of X86. The x64 CPUs work with both 32bit and 64bit programs and applications and can read and write data faster than an x86 one does, allowing him to work faster. Like example the x86 one has to process two 32bit files of data in a second, that’s 2 files with a total of 64 bits of data. While the x64 cpu can handle that in half the time the x86 one did. I hope it makes sense
