What does unencrypted mean?

Encryption is the process of translating data, particularly on the internet, into a secret code. In order to read this information, a computer needs a special key in order to decrypt it. This is a security method used to keep sensitive data, particularly passwords, credit card numbers, etc., safe. If your connection is unencrypted, it means that any data or information is sent in plain text and could be more easily compromised.
