Definition: bytecode


An intermediate language that requires a runtime program for execution. For example, the source code of Java and Microsoft's .NET languages is compiled into their particular type of bytecode, which is executed by their runtime engines (see Java and .NET Framework). WebAssembly, which can be used instead of JavaScript routines in Web pages, generates bytecode (see WebAssembly).




Java Bytecode
Java programs are compiled into bytecode, which is translated into machine language at runtime by the Java Virtual Machine (JVM). There are JVMs for almost every environment, enabling Java to run in most computers. See runtime engine.






No Bytecode - No Runtime Engine
In compiled languages such as C/C++, the machine language is executed in the computer. See C.
