Physical Computing is the smaller version of Virtual Computing ?
No — Physical Computing is not a smaller version of Virtual Computing.
They are different levels or layers of computing — not “bigger” or “smaller” versions of each other.
🖥️ Physical Computing → Base Layer
• It’s the foundation — the real hardware (CPU, RAM, disk, etc.).
• Virtual computing runs on top of physical computing.
• Without physical servers, virtualization cannot exist.
Example:
You have a physical server — like a Dell PowerEdge machine.
You install a hypervisor (e.g., VMware or Hyper-V) on it → that enables Virtual Computing.
💻 Virtual Computing → Logical Layer
• It uses software (hypervisor) to divide physical hardware into multiple virtual machines (VMs).
• Each VM behaves like a separate computer.
• This allows better resource utilization and flexibility.
What is the difference between Physical computing, virtual computing and cloud computing?
Physical computing = Your own computer.
Virtual computing = Many computers (VMs) inside one machine.
Cloud computing = Someone else’s powerful computers you use through the internet.
