vCPU stands for which term?

• A. Video Central Processing Unit
• B. Virtual Central Processing Unit
• C. Virtual Core Processing Unit
• D. Vector Central Processing Unit

Answer: (B)

vCPU stands for Virtual Central Processing Unit. In virtualization, the physical CPU resources of a host are abstracted into virtual CPUs that are presented to each virtual machine. “Virtual” means software-defined rather than a separate physical processor, and the hypervisor schedules these vCPUs onto the host’s actual cores or threads. This lets multiple VMs share CPU time efficiently while behaving as if each VM has its own processor. The other options don’t fit because they imply video, a different kind of core, or vector processing, none of which describe the CPU resource presented to virtual machines.
