1. The operating system assigns a virtual address ranging from 0 to 4G to each process.
2. Relationship between virtual memory and physical memory
Summary:
The minimum unit for memory management in program a is page (4096 bytes). If the required memory is less than 4096 bytes, it is actually 4096 bytes.
B. Each program corresponds to an independent virtual memory. When calling this function, you first need to find your own virtual memory. Then, you actually need to find the ph
