Programming Fundamentals

Machine Language (sequence 0,1) <- sign instead - Assembly Language

Machine-oriented (operated by control CPU instruction set) <- lower Language

High-level language -> close to nature and mathematics

 

High-level language - conversion tools (compilers C, C ++; interpreter Java, Python) -> low-level language

Compiled language: source code directly into the machine's CPU instructions

Interpreted languages: the interpreted byte code is converted to (bytecode The), running on a virtual machine, intermediate code executed by an interpreter
