Introduction to OOP

Chapter 27: Implementation :

Bytecode Interpreters

An implementation technique that is widely used (Smalltalk, Java, C#, Python)

Program is compiled into an ``assembly language'' for an imaginary machine.
Since this assembly code is often represented by a string of bytes, it is called bytecode.
Since the machine is imaginary, can run on any platform.
But it must be simulated (by a virtual machine) and hence you pay an execution time cost.
