Detailed explanation-1: -A virtual network is a networking system that emulates a physical network by combining the hardware and software network resources to form a single administrative unit. A virtual switch (vSwitch) is a central component in virtual networks.
Detailed explanation-2: -A virtual network connects virtual machines and devices, no matter their location, using software. In a physical network, layer 2 and 3 functions of the OSI model happen within physical switches and routers.
Detailed explanation-3: -Network virtualization software allows network administrators to move virtual machines across different domains without reconfiguring the network. The software creates a network overlay that can run separate virtual network layers on top of the same physical network fabric.
Detailed explanation-4: -Hardware virtualization is the method used to create virtual versions of physical desktops and operating systems. It uses a virtual machine manager (VMM) called a hypervisor to provide abstracted hardware to multiple guest operating systems, which can then share the physical hardware resources more efficiently.
Detailed explanation-5: -There are two kinds of network virtualization: external virtualization and internal virtualization.
