A Virtual Network is a software-based network that allows devices to communicate over the internet as if they were connected to a physical network. It uses technologies like VPNs (Virtual Private Networks) to create secure connections, enabling users to access resources remotely while maintaining privacy and security. These networks can be easily configured and scaled, making them ideal for businesses and individuals. They allow for the segmentation of network traffic, improving performance and security. Virtual networks are commonly used in cloud computing environments, where resources can be allocated dynamically based on demand.
