address space
This term is a technical specification used primarily in computer science and systems architecture. It describes the theoretical limit of memory that a CPU can reference, determined by the width of the address bus. For example, a 32-bit system is limited to a 4 GB address space.
In modern operating systems, a distinction is made between the physical address space, which refers to the actual hardware RAM installed, and the virtual address space, which is a logical abstraction allowing processes to behave as if they have a contiguous block of memory regardless of physical fragmentation.
Meanings
Examples
A 64-bit processor provides a significantly larger address space than a 32-bit one.
Each process is assigned its own virtual address space to ensure isolation.
We need to check if the requested memory exceeds the available address space.
The kernel occupies a specific portion of the system address space.
I wonder if this legacy application can even run in such a limited address space.
The MMU maps the virtual address space to physical memory locations.
Does the current architecture support a flat address space model?
The program crashed because it attempted to access an invalid address space.
