问题描述
此评论使我感到困惑:"kill -l通常列出所有信号".我以为信号意味着量化的能量.
This comment confuses me: "kill -l generally lists all signals". I thought that a signal means a quantized amount of energy.
[已添加] ,请阐明Unix中的(计算)信号和物理信号.他们是完全不同的概念吗?
[Added] Please, clarify the (computational) signal in Unix and the physical signal. Are they totally different concepts?
[添加] 范式之间是否有主要区别?在C,Python和Haskell等语言中含义是否相同?信号似乎是一个通用术语.
[Added] Are there major differences between paradigms? Is the meaning the same in languages such as C, Python and Haskell? The signal seems to be a general term.
推荐答案
