As the price of physical memory continues to decline, MB or even 1 GB memory has become the standard for installation. The increase in memory capacity has significantly improved the system performance. However, some people have suggested that: when the memory exceeds 1 GB, you do not need to set the virtual

In fact, this is a common problem in large proj

Heap memory or stack memory ?, Heap memory or There is a question in "Sword refers to Offer", "replacing the space in a character array with the string" % 20 "". I read the ideas in the book, then, when too many spaces are entered in the program I wrote, the error "memory clobbered before allocated block" will appear "

Uma and NUMA:Uma (uniform memory access), that is, consistent memory access. In this case, the cost of CPU access to any memory location is the same.NUMA) (non-uniform memory access), that is, non-consistent memory access. In this case, the cost of CPU access to

Original addressAllocation granularity: Indicates the minimum allocation for each memory request, such as a 32-bit operating system that basically allocates 64K of size each time. Paging Size: Represents the size of the page, the 32-bit operating system is 4K is the smallest unit of memory management.= 4K + 2K of space, the operating system will allocate a 64K of space at a time, and because the minimum

Many of my friends who use Windows 7 believe that Windows 7 is a 32-bit pre-installed computer, however, if my computer has 3G memory or above or wants to upgrade the memory, but Windows 7 is 32 and cannot identify memory above 3.25G, I can understand this confusion from many friends. The pre-installed Windows 7 is genuine, I don't want to spend any money on 64-b
