binary machine code

基本解释

Often the target language is a binary format like machine code, but not always.
目标语言通常为二进制格式（如机器代码），但不总是这种格式。
Is executed by the shell, then passed to the kernel, which is typically slower than a compiled binary program that is pure machine code.
由 shell 执行，然后传递给内核，这个过程通常比编译为纯机器码的二进制程序慢。
My understanding is that the application binary is already encrypted by the time it gets to a user device but this is only the binary and the machine code can still be accessed.
我的理解是，应用程序已经通过它得到一个用户装置，但这仅是二进制机器代码仍然可以访问加密的时间。
