C + + Bottom system concept (i)----assembly language was born

How does the computer work?

First look at the CPU

Look, this is the CPU.

CPU can only run binary code

Just like this.

101100000000000000000011

000010100000000001100000

......

Back to the time when the CPU was just born

It was programmed only with 0 and 1, and it was written dead.

......

A smart and diligent programmer

Wrote a 0 and a 1.

　　Text editing programs

The so-called text editing program is my keyboard what knocks a M your monitor shows I knocked out M also can save all the letters I knock.

With a text editor

So they can write a converter again.

Used to implement easy code codes

101100000000000000000011 very Long is the

I hit mov in a text editor

And then this converter program automatically put my MOV

Converted into 101100000000000000000011

So I can use the text to represent the code instead of the damn binary.

What happened in the end?

The birth of assembly language

Assembly language is the text code that corresponds to the binary code one by one

Assembly language can be run directly by the CPU after being converted into binary

So assembly language was the first to appear.

Assembly language is the direct manipulation of hardware languages
