![]() When written as two words, run time refers to how long the execution of a program takes.It is used as a noun to denote the final phase of a program lifecycle when the program is executed (as detailed above).However, the term is used other ways in programming: The main use of the term runtime is to describe the runtime environment - the code that allows a program to function. It can refer to the state of a program, a certain type of program or the time at which a program runs. The term runtime has many meanings in computer science. Programmers may have to debug the software, either manually or using debugging tools, to get to the root of a runtime error. Runtime is the final stage of the program lifecycle, when the machine executes the program code.Ī runtime environment usually displays a notification that gives the reason for the crash or where in the program the error occurred. It then makes the hardware run the program. That code is sent to the computer's processor to be turned into machine code. These may include code that the user did not write but that works in the background to make the program run. When an application is at the runtime stage, the executable file of the program is loaded into RAM, along with any files that the program references. These other programs handle tasks such as allocating memory for the main program and scheduling it. Some of these external instructions are called runtime systems or runtime environments and come as integral parts of the programming language.Ī runtime system creates a layer over the operating system ( OS) that contains other programs that handle the tasks needed to get the main program running. It is the time that a program is running alongside all the external instructions needed for proper execution. Runtime is a stage of the programming lifecycle. The former is sometimes called compile time. Programmers sometimes distinguish between what gets embedded in a program when it is compiled and what gets embedded or used at runtime. In some programming languages, certain reusable programs or " routines" are built and packaged as a "runtime library." These routines can be linked to and used by any program when it is running. That is, when you start a program running in a computer, it is runtime for that program. ![]() Runtime is also when a program is running. Runtimes are often integral parts of the programming language and don't need to be installed separately. In doing this, it allows the program to interact with the computing resources it needs to work. Runtime is a piece of code that implements portions of a programming language's execution model.
