What is the primary function of logs in a computer system?

The primary function of logs in a computer system is to record system events. Logs serve as a detailed account of activities and operations that occur within the system, capturing information such as error messages, system performance statistics, and user activities. This recorded data is invaluable for troubleshooting issues, monitoring system performance, and maintaining security, as it allows administrators to trace back events that may have led to problems or breaches.

By analyzing logs, IT professionals can identify patterns, detect anomalies, and respond to incidents effectively. This makes them essential for maintaining an operational understanding of a system and ensuring its reliability and security. Other functions, like data backup, application storage, and network security, are important in their respective domains but do not encapsulate the broad, vital role that logs play in ongoing system management and oversight.
