Virtual Networking is a technology that facilitates the management of disparate network functionalities in a software-based environment. It eliminates the need for physical hardware systems by emulating these systems in software, thereby providing more flexibility and scalability. Virtual networking enables the creation of diverse networks on a single physical infrastructure, increasing efficiency and reducing costs. This form of networking allows for rapid changes to network architecture, improving response times to changing business needs. It also enhances security through isolated virtual spaces and advanced controls, making it a significant tool in modern IT infrastructures.
