Native code is computer programming (code) that is compiled
to run with a particular processor (such as an Intel
x86-class processor) and its set of instructions. If the
same program is run on a computer with a different
processor, software can be provided so that the computer
emulates the original processor. In this case, the original
program runs in "emulation mode" on the new processor and
almost certainly more slowly than in native mode on the
original processor. (The program can be rewritten and
recompiled so that it runs on the new processor in native mode.)
Native code can also be distinguished from bytecode
(sometimes called interpreted code), a form of code that can
be said to run in a virtual machine (for example, the Java
virtual machine). The virtual machine is a program that
converts the platform-generalized bytecode into the native
code that will run in a specific processor. Microsoft's .NET
compilers for its Visual Basic, C#, and JavaScript languages
produce bytecode (which Microsoft calls Intermediate
Language). Java bytecode and Microsoft's Intermediate
Language can be compiled into native code before execution
by a just-in-time compiler for faster performance.
