[英]process virtual address space
I am reading some text about about the virtual address space of a process and it says that 我正在阅读一些有关进程的虚拟地址空间的文字,它说
If we have virtual address that are 32 bits long, the virtual address space of the process can be up to 4 GB.
如果我们具有32位长的虚拟地址,则该进程的虚拟地址空间最多可为4 GB。
This may be a silly question but how is 4 GB calculated? 这可能是一个愚蠢的问题,但是如何计算4 GB? How do you work it out from 32 bits?
您如何用32位计算出来?
2 to the power of 32 is what gives you 4 GB. 2到32的幂就是4 GB的大小。 So with 32 bits, you can refer a memory area of up to 4 Giga bytes of addresses.
因此,对于32位,您可以引用最多4 Giga字节地址的存储区。
