  #2 说错了 池是 pool

• 資深大佬 : whisp

  a study in which people are asked for their opinions about a subject or person
  可以理解为对所有人进行询问，得到的回复就是 poll 的结果

  维基百科上有词条专门解释了这个。我抽取 2 句吧：

  1. Polling, or polled operation, in computer science, refers to actively sampling the status of an external device by a client program as a synchronous activity. Polling is most often used in terms of input/output (I/O), and is also referred to as polled I/O or software-driven I/O.

  2. Polling is the process where the computer or controlling device waits for an external device to check for its readiness or state, often with low-level hardware.

  简单地说，poll 是(主动地)检查外部设备的(就绪)状态。这里的外部设备不一定指硬件，只要有(多种)状态，都可以拿来 poll 。
