Virtual Network
A Virtual Network is like a digital version of a traditional computer network, but it exists in the cloud instead of physical offices. Think of it as creating private, secure pathways for computers to talk to each other over the internet. Companies use Virtual Networks to connect their different offices, remote workers, and cloud services together safely, as if they were all in the same building. This is a fundamental concept in cloud platforms like Amazon AWS, Microsoft Azure, or Google Cloud, where it's sometimes called VNet or VPC (Virtual Private Cloud).
