The first part of the computer language classification:
- Machine language: A computer language that is expressed directly in binary code instructions, a string of code that consists of 0 and 1. For example: 1011011000000000, which represents addition. can be executed directly.
- Assembly Language: Assembly instruction set, pseudo-instruction set and the use of their rules collectively, using a certain meaning of the symbol as a mnemonic, with the instruction mnemonic, symbolic address, such as the symbolic instructions are called assembly format directives. For example:
- High-level language: High-level language programming programs can not be directly recognized by the computer, must be converted to be executed. For example: C language, must go through
C Source Program header file--pre-compile processing (CPP)--the compiler itself------and the assembler-----to the program----the executable file.
