I bet a lot of people continued to write machine language until the processor, like a bartender eager to close up and go home, finally kicked them out by switching to a RISC instruction set.

我打赌，很多人会一直用机器语言写下去，直到有一天，处理器换成了RISC指令集-就像急着下班的酒吧服务员急着关门一样，端掉这些人的饭碗。

In Chapter 2, we learned that the processor fetches and executes a single instruction during each machine cycle.

在第二章中，读者知道了在每个机器周期内处理器取出并执行一条指令。
