"VPN" typically stands for "Virtual Private Network," which is a type of internet service designed to provide a private, secure connection to the internet. It allows users to access the internet over a public network, but does so through a virtual private network that is secure and private.

- VPN: A VPN is a network service that allows users to connect to the internet over a private network. It encrypts and secures the connection, making it difficult for third parties to monitor the traffic.
- VLAN (Virtual Local Area Network): A VLAN is a virtual network that runs over a physical network. It uses subnet masks to separate different networks. VLANs are used to isolate networks, ensure security, and manage network traffic efficiently.
