What is a virtual network? What advantages does it have?

A virtual network is a network created, managed, and implemented by software instead of physical network devices, servers, and infrastructure. Virtual networks enable data transfer between connected devices or servers regardless of physical distance. They can also operate in hybrid or cloud environments, facilitating easier network management. The key advantages of virtual networks include:
1. Flexibility: Virtual networks offer an easier way to set up and manage infrastructure, increasing productivity and enabling the addition of new devices more seamlessly.
2. Innovation: Virtual networks support new technologies and automated management, making it easier for networks to embrace innovations and adapt to changes.
3. Security: Virtual networks provide better capabilities for implementing protection and control measures, enhancing security measures.
4. Cost Reduction: Virtual networks reduce financial costs by eliminating the need for physical infrastructure to provide required services, thereby reducing organization expenditures.
5. Flexibility in data flow and connectivity: Virtual networks offer easier ways to share data and establish connections between various devices and platforms.
