How do VPNs enhance privacy and security while browsing online?.

VPNs (Virtual Private Networks) enhance privacy and security by creating a secure tunnel for internet traffic, ensuring that data transmitted between the user and the internet is encrypted. This encryption protects sensitive information, like personal details and payment information, from cybercriminals. Additionally, VPNs mask users' IP addresses, making it harder for websites and third parties to track online activities.
