A VPN, or Virtual Private Network, is a service that creates a secure and private connection over the Internet. It encrypts the data being sent and received, making it harder for others to intercept or monitor online activities. A VPN allows users to connect to the Internet as if they were in a different location, by routing their connection through a remote server. This can help protect privacy, access content from different countries, or secure communication over public networks, such as Wi-Fi in cafes or airports.

Phishing is a type of online scam where attackers attempt to trick people into giving away sensitive information, such as passwords, credit card numbers, or personal details. This is often done by sending fake emails, messages, or websites that appear to be from trusted sources, such as banks or online services. The goal is to deceive the recipient into clicking a link or entering their information, which can then be used for fraud or identity theft. Phishing can be harmful if not recognized, as it can lead to financial loss or security breaches.
