What is log meaning?

In computer science, a log is a file that stores a record of events or actions taken by software or a system. These can include error messages, usage statistics, and user interactions. Logs are often used for troubleshooting and debugging purposes, as they can help identify problems or issues that occurred during a specific period of time. They can also be used for performance analysis, security auditing, and compliance. Logs are typically stored in a specific format, such as the Common Log Format (CLF) or the Extended Log Format (ELF), which allows them to be easily parsed and analyzed.
