What is a secure connection?

A secure connection refers to an encrypted link between a user and a server, which is typically indicated by "HTTPS" in the URL instead of "HTTP." The "S" at the end stands for "Secure," meaning that the data transmitted over this connection is encrypted, providing an additional layer of security.

This encryption protects sensitive information, such as personal data, passwords, and credit card numbers, from being intercepted by third parties during transmission. Secure connections are essential for ensuring that users can communicate with websites safely, especially when transferring sensitive information.

In contrast, unencrypted connections and those that use "HTTP" do not provide this level of security, making the data more vulnerable to interception and exploitation. Additionally, a direct connection to the internet without a router does not inherently imply any level of security, as there are no encryption measures involved. Therefore, the correct choice highlights the crucial aspect of encryption in safeguarding information transmitted over the internet.
