![]() ![]() This program is rather complex since it not only creates machine language instructions from lines of code, but often also optimizes the code to run faster, adds error-correction code, and links the code with subroutines stored elsewhere. The program that accomplishes the translation is called a compiler. To do this translation is to compile a program. Likewise, programs written in high-level languages, like Pascal, must also be translated into machine language before they can be run. Assembly language programs are assembled, or translated into machine language. Microprocessors can only run machine language programs directly. One command in a high-level language, like writing a string to a file, may translate to dozens or even hundreds of machine language instructions. High-level languages include Pascal, C, C++, FORTRAN, Java, Visual Basic, C#, Java, and many more. ![]() High-level language - permits humans to write complex programs without going step-by step.For example, in Intel x86 machine language, ADD and MOV are mnemonics for the addition and move operations. There is a one-to-one correspondence with machine code. Assembly language - a way for humans to program computers directly without memorizing strings of binary numbers.For example, on x86, add eax, 5 becomes 0x83, 0xC0, 0x05, while mov ax,bx becomes 66 89 d8. These are usually very simple commands like adding two numbers or moving data from one memory location to another. Machine language - actual binary code that gives basic instructions to the computer's CPU.When talking about computer languages, there are basically three major terms that will be used. 1 About Computer Languages and Compilers.
