Which of the following is NOT a form of computing virtualization?

Storage architecture virtualization is indeed not specifically classified as a form of computing virtualization. The concept of computing virtualization typically refers to the abstraction of hardware resources, creating a virtual layer that allows multiple virtual machines to operate on the same physical machine.

CPU virtualization refers to the process of emulating a physical CPU, allowing multiple operating systems to use the CPU simultaneously through virtual machines. Network virtualization involves combining hardware and software network resources into a single, software-based administrative entity, which enhances network management and efficiency. Memory virtualization, on the other hand, abstracts the memory management of multiple machines into a single virtual memory space, making it appear as though all connected systems are sharing a single pool of memory resources.

In contrast, storage architecture virtualization refers more broadly to the way storage systems are structured and managed but does not fit into the standard classifications of computing virtualization such as CPU, network, or memory virtualization. Instead, it deals with how storage devices (like disks) are pooled and managed, which is a key aspect of storage management rather than computing itself.
