Word to describe the size of the operating system?

Question

I want to have an enumeration describing the "width" of the operating system.

The values ​​will be OS32 or OS64, but what is a good name to list it yourself?

enum OS_SIZE
{
   OS32,
   OS64
}

The best I can think of is OS Size, or maybe OS Word Size, but I don’t really like it. Is there an industry term used to describe the width of the main word of the operating system?

Answer 1

• Bitness
• PointerSize
• WordLength.

Answer 2

WMI calls it AddressWidth, for example.

Answer 3

, : 32 64 , .

In any case, the main difference from the point of view of hardware architecture, so I would say "The number of bits in the architecture address", NoBiAA or simply " ARCH_ADDR_SIZE".

Answer 4

OSWordSizeand OSWordBitSizework for me.
