虚拟内存空间 [英] Virtual Memory Space
问题描述
虚拟内存空间大小取决于什么?它是否取决于RAM或体系结构还是其他?
What does the virtual memory space size depend on? Does it depend on the RAM or on the architecture or something else.
推荐答案
基本上,它取决于体系结构(32位,64位等等). 这是对事物的一种非常简单的解释,但是所谓的体系结构"限制了虚拟地址空间的大小.例如,32位体系结构将允许寻址2 ^ 31个存储器地址.
Basically it depends on the architecture (32bit 64bit and so...). This is a very simplistic explanation of things, but so called "architecture" limits size of the virtual address space. For example, 32bit architecture will enable to address 2^31 memory addresses.
RAM的大小将限制可以使用的物理内存量,而不是虚拟地址空间. (可能可以使用硬盘驱动器来扩展可用的物理内存)
The size of the RAM will limit the amount of physical memory that can be used, but not the virtual address space. (potentially the Hard-drive can be used to extend the available physical memory)
无论如何,我建议阅读虚拟内存
Anyway I recommend to read the wiki page on virtual memory
