Or does CS50 already exist in machine code somewhere beneath?

或者CS50已经存在于机器代码下面的某个地方？

And compiling means going from source code to machine code.

编译意味着从源代码到机器代码。

It seems to have compiled into machine code.

它似乎已经编译成了机器代码。

And my output, ideally, is going to be what we'll call machine code.

理想情况下，我的输出就是我们所说的机器代码。

It reads in a program written in an Assembly Language and converts it to native machine code.

它读入用汇编语言编写的程序并将其转换为本地机器代码。

In the early days of computing, people had to write entire programs in machine code.

在计算的早期，人们不得不用机器代码编写整个程序。

That is the machine code that the compiler has created for me.

这是编译器为我创建的机器代码。

Then the FORTRAN Compiler would translate and expand that into native machine code.

然后 FORTRAN 编译器会将其翻译并扩展为本机机器代码。

Then it assembles it into machine code until we have the actual 0's and 1's.

然后它将其汇编成机器代码，直到我们得到实际的0和1。

To do this, they needed to write a program that converted BASIC instructions into native machine code, what’s called an interpreter.

为此，他们需要编写一个程序，将 BASIC 指令转换为本地机器代码，即所谓的解释器。

However, even with nifty assembler features like auto-linking JUMPs to labels, Assembly Languages are still a thin veneer over machine code.

然而，即使有漂亮的汇编程序功能，如自动将 JUMP 链接到标签，汇编语言仍然只是机器代码的一层薄薄的外表。

It's true of most programming languages today, a benefit of moving away from assembly and machine code, which is still CPU specific.

今天的大多数编程语言都是如此，这是摆脱汇编和机器代码的好处，它们仍然是特定于 CPU 的。

However, these programs still had to be written in machine code, which was really low level and nasty, even for hardcore computer enthusiasts.

然而，这些程序仍然必须用机器代码编写，这确实是低级和令人讨厌的，即使对于铁杆计算机爱好者来说也是如此。

But in April 2020, just after the decade mark, we were thrilled to be able to announcewhat seems to be the ultimate machine code of the universe.

但在 2020 年 4 月，就在十周年之后，我们很高兴能够宣布似乎是宇宙的终极机器代码。

Then, when the program was all figured out on paper, they'd painstakingly expand and translate it into binary machine code by hand, using things like opcode tables.

然后，当程序全部在纸上弄清楚时，他们会使用操作码表之类的东西，煞费苦心地手动将其扩展并翻译成二进制机器代码。

Within about 50 years, software grew in complexity from machine code punched by hand onto paper tape, to object oriented programming languages, compiled in integrated development environments.

在大约 50 年的时间里，软件的复杂性从手工打到纸带上的机器代码发展到在集成开发环境中编译的面向对象的编程语言。

And they then wrote code, usually machine code, sometimes binary code, which was then sent by mail to a data center to be punched onto paper tape or card and then re-punched, in order to verify it.

然后她们写代码，通常是写机器代码，偶尔写二进制代码，这些代码通过邮件，被寄到数据中心，打在纸带或卡片上， （那时的程序是通过在纸带上的孔来让计算机读取的）反复打孔，确保无误。

This is a specialized program that transforms " source" code written in a programming language into a low-level language, like assembly or the binary " machine code" that the CPU can directly process.

这是一个专门的程序，可以将用编程语言编写的“源”代码转换为低级语言，如汇编或 CPU 可以直接处理的二进制“机器代码”。
