The network names are created when you install the VMware product and depend on which product and/or version you use. If new network adapters (physical or virtual) are installed with defaults, Windows detects them and assigns names like "Local Area Connection n" where "n" will be increased for each newly detected adapter. It's also possible to create new network adapters with predefined names, that's when you see names like "VMnet Adapter for VMnet1".
