Runtime refers to the period when a program is executing, as opposed to when it is being written or compiled. It is the phase during which the program instructions are loaded into memory and carried out by the computer’s processor.
Key aspects of runtime:
Errors that occur during execution are called runtime errors.
Runtime environments provide the resources needed for program execution, such as memory allocation, input/output handling, and managing program flow.
Examples:
In Java, the Java Runtime Environment (JRE) provides the necessary environment to run Java programs.
In JavaScript, runtime includes the browser’s JavaScript engine.
