Terms

Term: Machine language
Intro: Sometimes referred to as?machine code?or?object code,?machine language?is a collection of?binary?digits or bits that the computer reads and interprets. Machine language is the only language a computer is capable of understanding.
How it works: the computer converts machine instructions (a list of binary digits) to a high and low level, which drives the computer‘s electronics to perform calculations.
Supplement: each type of processor is designed and constructed differently, so it generates different electronic pulses, and hence different machine languages.

Term：CPU 「Central Processing Unit」
Intro：Interpreting machine instructions

Term：Computer // PC
Intro：A computer system consisting of a CPU and other chips, devices, and devices directly or indirectly controlled by the CPU.

Instance

    s = 768 + 12288 - 1280
    The machine code following：
    10110000000000000000011
    00000101000000000001100
    00101101000000000000101

Instance

It's on the screen：“welcom to masm”
The machine code following：

    0001110
    101110000000000000000000
    01010000
    101110001100011000001111
    1000111011011000
    1011010000000110

Shortcoming

if you mistake a 1 for a 0, it‘s hard to find.
