In this series we help you understand the bits and pieces that make your code command the underlying hardware. A multitude of layers translate and optimize source code, written in compiled and interpreted programming languages such as C++, Python or Java, to machine language. We explain the role and behavior of the layers in question in a typical usage scenario. While our main focus is on compilers and interpreters, we also talk about other facilities - such as the operating system, instruction sets and instruction decoders.
