32-bit processors
on x86-64 processors, yes. On Itanium, no.
The term refers to hybrid processors
Actually, they both make what are known as x86-64 processors, which are processors that can run both 32-bit and 64-bit programs. Check the specifications of the processor for something like "64-bit" or "64-bit Ready" to make sure you can run both x86 (32-bit) or x64 (64-bit) programs!
IBM AIX currently only supports Power chip processors, which are not the Intel X86 format.
x86
Any x86 processor from the 386 on up to present-day processors can be used with Windows 98.
Planned x86 processors will have the SSE4 instruction set.
Yes, Apple's Intel transition was the process of changing the CPU of Macintosh computers from PowerPC processors to Intel x86 processors.
All of them. All drivers for video cards running on x86 processors are compatible with Celeron processors.
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.
ARM is a processor architecture that incorporates a few different types of microprocessor that isn't built on the x86 protocol. They are called processors because they ARE processors.
