That’s exactly what it means; it’s the environment and data structures that keep track of everything that’s going along as your program runs. It’s not only interpreted languages that have a runtime environment, so does every compiled language. In C, the runtime is the environment variables and operating-system provided services that let the program interact with the rest of the system. In an object-oriented language, it’s also all the tables of objects and classes and methods that get built to allow message passing to take place. In an interpreted language, it’s the state of the interpreter, plus all of those other things. In general, I guess you could describe the runtime as “everything that happens that you didn’t explicitly write yourself”.
