. It is the paging unit that divides all physical memory into fixed-length management units whose length is typically one by one corresponding to the memory page. Note here that this total_page array has 2^20 members, each member is an address (32-bit machine, one address is 4 bytes), then to represent such an array, it takes up 4MB of

I was also baffled at first, th

Directory Entries determine the address of the physical memory page. There can be more than one entry pointing to the same physical address. The complete physical memory address is determined by the combination of the page address obtained from the page Directory and the Low-byte part of the virtual address. The page Directory Entries also contain additional pag

then operates as a reference to this memory through a Directbytebuffer object stored in the Java heap. This can significantly improve performance in some scenarios because it avoids copying data back and forth in the Java heap and native heap.Obviously, the allocation of native direct memory is not limited by the size of the Java heap, but since it is memory, it

Virtual memory is a Laosheng long talk problem, since the memory bar with "G" for units and prices all the way down, the problem of virtual memory shortage seems to be an ancient problem. Some people say that a computer with high memory
