Overall, a VPN can encrypt your internet traffic and keep your browsing activities hidden from others on the public web to an extent. Your ISP won't be able to tell what you're doing either. They can only see that you're using a VPN.
VPNs are important because internet connections can be eavesdropped easily by malicious cybercriminals. Whether you are using wireless or wired connections, your data might be visible to others that can access the network.
