x86, x86-64, and PowerPC.
IBM AIX currently only supports Power chip processors, which are not the Intel X86 format.
HP-UX runs on the PA-RISC and IA-64 (Itanium) architectures. Earlier versions also ran on certain m68k equipment.There is currently no version for x86 or x86-64.
The X86 64 is considered to refer to the central processing unit for computers. The X86 64 predominantly supports both physical and virtual memory on computer systems.
That heavily depends on what operation systems you want to use. A normal answer would be Windows XP, or a Linux OS.
There aren't really kinds of processors, they have different architectures. There are thousands with the most popular kind of architecture in processors are x86/x64 and ARM.
x86 and x86-64 (x64) are not mutually exclusive. x86-64 is a superset of x86, with 64-bit instructions. Many people still run 32-bit (x86) applications and operating systems on 64-bit processors. The reverse is not possible, though; you can't run a 64-bit system on a processor that only supports 32-bit.
Intel has actually manufactured several incompatible architectures. The 4004, 8008, and 8080 are all incompatible. The 8086, 8088, 80286, 80386, 80486, Pentium (II, III, 4), and Core (2) are all backwards-compatible processors classified as "x86." Intel also created the i860 and IA-64 (Itanium) architectures.
the most common is the i486 Intel architecture with x32 or x86 systems, althought x64 system architectures (AMD0 are more and more common nowadays)
HP officially supports Windows HP Home, Windows Vista Home Basic x86, and Windows Vista Business in x86 and x64. The machine is also capable of running Windows 7 if it is equipped with enough RAM.
Porting is the process of modifiying the operating system code to make it run on new CPUs and system architectures. For example, if the operating system was originally written to run on x86 CPUs and was later modified to run on ARM processors.
Vista x86 supports 3.8GB. It means that 4 GB it's maximum you can install. If you compare 2GB installed with 4GB, 4GB configuration will provide a better working experience.
