A little used and relatively new feature is the RAM disk, which allows for the use of physical RAM as the storage for a file system.

一个不常用并且较新的特性是RAM磁盘，它允许使用物理ram存储文件系统。

During the boot of the kernel, the initial-RAM disk (initrd) that was loaded into memory by the stage 2 boot loader is copied into RAM and mounted.

在内核引导过程中，初始ram磁盘(initrd)是由阶段2引导加载程序加载到内存中的，它会被复制到RAM中并挂载到系统上。

It works by placing the files on a RAM disk (it cuts down RAM for applications, slowing performance, but remember, our goal is to assess the system's security).

它在工作时将这些文件放到一个RAM磁盘上(这样就减少了应用程序可以使用的RAM数量，从而会降低系统的性能，但是不要忘了，我们的目标是评估系统的安全性)。

RAM You probably know your computer has something called RAM which is where documents and programs live just temporarily while you're running them 'cause RAM tends to be pretty fast and whereas your hard disk is where programs and files live permanently.

也许你知道电脑有一个,正在使用的程序和文件都暂时存放在那里,而且会加快电脑速度,而硬盘是程序和文件,永久存储的地方。

When you're working on a file, it's saving constantly to RAM but also hopefully to disc, the hard disk so you don't actually lose it if the power goes off.

当你打开一个文件，它不断地保存在内存中,但对于光盘，硬盘,当你断开电源的时候，数据不会丢失。

Because you can come up with an infinite number of values but if you have a finite amount of space and certainly a computer has a finite amount of disk space or RAM, you have to make approximations.

你可能会碰到一些无限的值,如果你只有有限的空间,废话，电脑当然只有一个有限的磁盘空间,或RAM，我们得做一些近似处理。

If "barebones" isn't quite your style, Apple has a spankin' 4, 976, 640 configurations to choose from, ramping up to a ATi Radeon 1900 or Quadro FX 4500 GPU, 16GB of RAM and 2TB of disk space.

The device also comes standard with 4GB RAM, expandable to 8GB, and a 320GB 7200rpm hard disk drive, with an optional 128GB solid state drive available.

And AgigA Tech makes so-called non-volatile Random Access Memory (RAM) that helps people store and retrieve rapidly changing data far more quickly than the slow-poke disk drive technology that keeps data centers humming.
