## Hypervisors: Type 1 vs Type 2

The software that runs VMs.

### Type 1 (Bare Metal)
*   **Installs**: Directly on the hardware. NO Windows/MacOS underneath.
*   **Performance**: Extremely fast.
*   **Usage**: Enterprise/Servers.
*   **Examples**: VMware ESXi, Microsoft Hyper-V (Server), Proxmox.

### Type 2 (Hosted)
*   **Installs**: Like an app on your existing OS.
*   **Performance**: Slower (overhead of the Host OS).
*   **Usage**: Laptops/Desktops.
*   **Examples**: VMware Workstation, Oracle VirtualBox.
*   **Student Lab**: You will use Type 2 (VirtualBox) because you don't want to wipe your laptop.
