What does parameterized building in Jenkins refer to?

Parameterized builds in Jenkins refer to the ability to set some parameters during the build process, in order to make the build more flexible and customizable. By using parameterized builds, different parameter values can be input during the build process, resulting in different build outcomes or behaviors. This allows for easy implementation of build requirements in different environments, versions, configurations, etc. Common parameter types include strings, booleans, numbers, etc., and users can customize parameters as needed and input them during the build process.
