Therefore, the amount of time required for any particular memory access is completely unknown (if the memory is swapped out, who knows how long it will take).
因而，某一内存访问所需的时间是完全未知的(如果内存被换出，所需时间的长短是不可知的)。
We've also presented and explained how to use several powerful new features, such as revalidation in memory and access to type information — something developers have been asking for for a long time.
我们还展示并解释了如何使用几个强大的新特性，例如内存中的重新验证以及对类型信息的访问——这些都是开发人员长期以来梦寐以求的特性。
Why can't you access a 4 byte long variable in a single memory access on an unaligned address(i. e. not divisible by 4), as it's the case with aligned addresses?
为什么你不能访问一个4字节长的变量在未对齐地址（即不被4整除）一个内存访问，因为它与对齐地址的情况？
The reason that this process takes so long is that a computer's operating system must be loaded from its hard disk into its random-access memory (RAM) every time the machine is turned on.
这个过程花这么长时间的原因是，每当打开计算机时，计算机的操作系统必须从硬盘载入到随机存取存储器(RAM)。
