Compiled language

A compiled language is a type of programming language where, instead of stepping through each instruction of a program (like an interpreted language) the source code is converted into machine code by a compiler.

During compilation, the compiler generally converts the source code into intermediate representation, and finally into machine code.

Bytecode languages

For some programming languages, instead of directly compiling to machine code, the source code is instead converted to a format known as bytecode.

This bytecode can't be directly executed by the CPU, but can be interpreted using an interpreter, often known as a process virtual machine.
