What is a virtual network and a VLAN and how are they different?

I will give an explanation using the widely accepted definition of these terms, but they are often exchanged.

VLANs connect physical clients together as if they were in a LAN, even if they are in different locations and on different physical networks.

Virtual networks connect Virtual Machines together in a completely virtual environment where both the clients and network are virtual.

VLAN lets you and your buddies be in a “pretend” LAN connection over the Internet. This lets you play LAN games together. Try the Radmin program, it’s a simple and easy way to play some CS 1.6.

Virtual Networks are special rules that let you make a secret, small members-only network within a big existing network. Like your Big Company has only 1 router and 50 PCs, 45 of which are employees and 5 are bosses. Even if they’re all on the same network in the physical world, you can make a special, secret virtual network for only bosses and one more virtual network for only employee computers.

This prevents the boss PCs and the employee PCs to interact with each other, as if they were in completely different networks, on different routers.

Virtual Networks are what big companies use to keep their clusters of computers safe from one another; if all the employee PCs got infected or hacked, the boss PCs are safe despite being on the same physical network.
