Which of the following is being described when using a single physical server to host multiple logical servers to more effectively utilize hardware resources?

Application virtualization isolates applications from the underlying operating system and other applications, allowing them to run in a virtual environment but does not involve multiple logical servers on a single physical server.

Multicore processing refers to a single CPU having multiple processing units (cores) to execute multiple instructions simultaneously, which is a hardware feature, not a method of hosting multiple logical servers.

Server virtualization allows a hypervisor to create and run multiple virtual machines on one physical machine, each acting as an independent server. This abstraction of hardware resources enables more efficient use of the underlying CPU, memory, and storage, as workloads can be consolidated onto fewer physical machines.

Hyper-threading is a technology that allows a single CPU core to run two threads concurrently, improving CPU utilization but not creating multiple logical servers from a single physical server.
