Runtime

Runtime refers to the duration in which a computer program is actively executing instructions. It begins when the program starts running and ends when it terminates. During runtime, the program is in a state of execution, utilizing system resources such as CPU, memory, and I/O operations to perform tasks and produce results. The term contrasts with other phases of the software lifecycle, such as compilation, where the program is being translated into machine code, or development, where the program is being written and debugged. Understanding runtime is crucial for optimizing performance and troubleshooting issues, as various runtime environments can impact how effectively a program runs.
