NDIS is an API (application programming interface) for NICs (network interface cards). When enabled, NDIS provides always-on connection without requiring VZAccess Manager to be open. Some background processes and programs may transfer data (e.g. Windows Update) even when not actively using the computer. It is recommended to check usage for potential overages. Refer to Determining Data Usage - VZAccess Manager (Windows) for additional assistance.
