The concept being tested is an intermediate, platform-agnostic form of code that runs through a virtual machine rather than directly on the processor. This is bytecode. Bytecode is produced by a compiler from a high-level language and is designed to be executed by a runtime environment (a VM) that interprets or JIT-compiles it into native machine instructions on each platform. This setup enables the same bytecode to run on any system that has a compatible VM, giving true portability across operating systems and hardware. In contrast, assembly language targets a specific processor architecture and is translated into native code for that CPU, so it isn’t portable. Plain code or code blocks don’t specify this execution model and aren’t inherently portable across platforms.
