The Raspberry Pi has a ton of different uses. Since it's small and energy-efficient, uses such as a network-attached storage (NAS) device, media server, game server, smart home hub, or any number of Internet of Things (IoT) projects run extremely well on the Raspberry Pi. Since the credit-card-sized Raspberry Pi sports a tiny footprint and sips power, it's ideal for an always-on device. And with superb internet connectivity, whether running on a wireless network or via a wired Ethernet port, the Pi is suitable for handling network traffic.

What Is a VPN and Why Should You Use One?
Ok, so what is a VPN? It's a virtual private network, a means of connecting to the internet with a secure, private connection. Rather than using your IP address, network traffic is routed through a gateway server, so you'll have a public-facing IP address of another location. For instance, you might be located in New York City, but with your VPN, making it look as if you're connecting in London, UK.
