For technical reasons, a COMA server may need to make a distinction between instantiation of components in a process with a 32-bit or 64-bit address space. The term bitness refers to the distinction between 32-bit and 64-bit address spaces and the potential differences in instantiation of components that this entails. For example, the target ORB may provide a local interoperability mechanism that instantiates a component in its creator's process.
