Explanation
A virtual switch (vSwitch) is a software-based Layer 2 switching device that runs within a virtualization platform (like VMware ESXi or Hyper-V). It operates at OSI Layer 2, forwarding Ethernet frames between virtual machines (VMs) and connecting VMs to physical networks, just like a physical switch. A virtual router operates at Layer 3, handling IP routing between networks-not a Layer 2 device. A virtual PBX is a software-based telephone system for voice communications. NaaS (Network as a Service) is a cloud service model that delivers networking capabilities over the internet-it is not a specific virtual device instance.
