为什么将4B5B和8B10B归类为行代码？
我一直在阅读 https://en.wikipedia.org/wiki/wiki/line_code 对我来说并不明显为什么4B5B和8B10B称为行代码。 行代码和更复杂的锤子代码之间的基本区别是什么？
I have been reading https://en.wikipedia.org/wiki/Line_code, but it is not obvious to me why 4b5b and 8b10b are called line code.
What is the fundamental difference between line code and more sophisticated hamming code?

他们俩都有完全不同的目的。
线代码在单个序列位流上启用时钟恢复，并提供位级同步。它还可以提供字节级同步。在差分电缆电缆上，线码（通常与crambler结合使用）也需要消除直流偏置。
锤子代码添加了冗余位，以进行正向误差校正。
They're both serving entirely different purposes.
A line code enables clock recovery on a single, serial bit stream and provides bit-level synchronization. It may also provide byte-level synchronization. On differential electrical cabling, the line code (often in combination with a scrambler) also needs to remove DC bias.
A hamming code adds redundant bits for forward error correction.
基本差异是代码的目的。
线代码用于调节传输线上的数据。通常，为了平衡发送的0位和1位的数量以平衡电流（4B5B和8B10B代码），
用于校正代码进行错误校正 - 检测传输错误并可能正确。
The fundamental difference is the purpose of the code.
A line code is used to condition the data on a transmission line. Generally to balance the number of 0 and 1 bits sent to balance the current (what both 4b5b and 8b10b codes so)
A hamming code is used for error correction -- to detect transmission errors and possibly correct for them.
