ram disk

基本解釋

Note that you can back indexing by many different sources, for example, a RAM disk.
請注意，可以根據(jù)很多不同的源（例如，RAM 磁盤）進行反向索引。
Not all functions that are involved in copying and mounting the initial RAM disk are shown here, but this gives you a rough overview of the overall flow.
盡管此處并沒有列出拷貝和掛載初始 RAM 磁盤所涉及的所有函數(shù)，但是這足以為我們提供一個整體流程的粗略框架。
This, along with its dynamic resizing abilities, allow for much better overall OS performance and flexibility than the alternative of using a traditional RAM disk.
這一點連同它動態(tài)調(diào)整大小的能力，比選擇使用傳統(tǒng)的 RAM 磁盤可以讓操作系統(tǒng)有好得多的整體性能和靈活性。

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.
也許你知道電腦有一個,正在使用的程序和文件都暫時存放在那里,而且會加快電腦速度,而硬盤是程序和文件,永久存儲的地方。

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.
當你打開一個文件，它不斷地保存在內(nèi)存中,但對于光盤，硬盤,當你斷開電源的時候，數(shù)據(jù)不會丟失。

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.
你可能會碰到一些無限的值,如果你只有有限的空間,廢話，電腦當然只有一個有限的磁盤空間,或RAM，我們得做一些近似處理。
