In simple words, a VPN, or Virtual Private Network, is like a secret tunnel for your internet traffic. Normally, when you go online, your data travels across the open internet where others could potentially see it. A VPN creates a private pathway that hides your online activity from your internet provider, hackers, and websites. It also changes your virtual location by letting you connect through a server in another city or country. Think of it as a disguise for your device—it hides who you are and where you are, making your online experience more private and secure.
