The differences between x32 and x64 Technology Full Explaination
A 32-bit processor can access a maximum of 4GB of memory, which isn't enough these days. It might be fine for basic tasks, but if you want to run multiple programs, have 35 tabs open in various web browsers or open 30 high-resolution photos for editing at once, 4GB isn't going to cut it. (And don't forget that 32-bit Windows can access only around 3.2GB even if 4GB is installed. PCs and laptops and their operating systems are all 64-bit these days. 64-bit versions of Windows 8 can access 8TB of RAM http://msdn.microsoft.com/en-gb/library/windows/desktop/aa366778(v=vs.85).aspx, while server versions can access 128TB. However, you'll struggle to afford such enormous amounts of memory, let alone install it into today's motherboards which typically top out at 32GB over four slots. x86 vs x64: What does the jargon mean? This somewhat misleading term is the equivalent of 32-bit vs 64-bit. x86 (or x86 architecture) has long been a common way to refer to the family of processors ending in 86, Intel's most successful line of processors. The first was the 8086, and many people will remember the 286, 386 and 486 processors in early PCs from the mid-1980s to 90s.Read All Details
