Document Summary

Adding the registers 1 and 2 and placing the result in register 6. Originally programmed by turning toggle switches on and off on the front of a computer. Extensive knowledge of computer hardware must be known in order to program. Machine language is different for every computer that you program it on. Very little programming is still done in machine code funct. Easier to program in than machine code, but still difficult to program. Assembly language uses symbolic codes to represent pieces of machine language. Looking at the above code you can notice that it has the word mov . Mov is an opcode that tells the computer to to take the value 72h and put it into register. Every opcode and value in assembly language is really just a representation of a binary equivalent. Programmers no longer needed to know exactly registers were connected inside the language that allowed programs to be written that worked on any computer computer.
