Logging: Recording useful messages about what an application is doing — events, warnings and errors — so people can investigate problems later.
Example
You log a message when an order fails, including the order ID, so support can trace what happened.
Why Logging matters for IT interns
In real systems, logs are often the only way to understand a problem. Never log passwords or personal data.
Where you will hear it
You will hear this term in development teams, in code reviews and technical discussions, and in technical interviews. If someone uses it and you are not sure what they mean in your project, it is completely fine to ask; every team uses terms a little differently.
