# ItC Week 10 - Machine Language

###### tags: `Intro_to_Comp`

- ## Introduction
- Machine language can be view as a programmer oreiented abstraction of the hardware platform
- Assembler translate assembly to binary codes

- ## Assembly
- Insturction
- Assembly Language : human-readible
- Machine Language : computer-readible
- Assembler : translates
- Example
- C version

            int i = 1;
            int sum = 0;
            while(i<=100){
                sum += i;
                i++;
            }

- "Hack" Machine Language version

                @i
                M=1
                @sum
                M=0
            (LOOP)
                //test if i <= 100
                @i
                D=M
                @100
                D=D-A
                @END
                D;JGT
                //"real" loop content
                @i
                D=M
                @sum
                M=D+M
                @i
                M=M+1
                @LOOP
                0;JMP
            (END)
                @END
                0;JMP
