Usage Notes

代码 in its primary modern sense refers to computer programming code. It can also refer to coded systems in general (e.g., QR codes are sometimes called 二维码, not using 代码). In technology contexts, 代码 is the standard term for source code or programming code.

Related terms include 程序 (program), 软件 (software), 算法 (algorithm), and 编程 (programming). 代码 is central vocabulary for any discussion of software development, cybersecurity, or the technology industry.
