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
the interface in Delphi, so that when you use the interface, you know its why.The distribution of interfaces in memoryAn interface is conceptually not an entity, it needs to be associated with a class that implements an interface, and if you break out of these classes, the interface becomes meaningless. But the interface still has its layout in memory, which is attached to the object's memory space.The Del

Physical Memory:The actual memory used;Virtual Memory:Virtual memory is a logical memory space concept designed by the operating system kernel in order to manage the process address space (management). The pointers in our program are actually the addresses in this virtual memory space. For example, after we have writte

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 "
is used to support 32-bit data processing volume.
30PIN:30-sided Memory module is used to support 8-bit data processing volume.
DIMM (Dual in-line Memory Module): (168PIN) used to support 64-bit or wider bus, and only 3.3 volts, usually on 64-bit desktop computers or servers.
The Rimm:rimm module is one of the main specifications for the next generation of memory
Article Title: Linux memory monitoring Memory leakage and memory recovery methods. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Memory overflow (out of memory): When memory space is low and more memory space is needed, it can overflow memory, such as loading large pictures into memory, which usually results in
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

maximum clock frequency is 400 MHz, the memory bus width is 16 bits, and each clock data segment is 2, then the formula is (400x16x2)/8 = 1600 Mb/s. As you can see, the pc2100 DDR memory can provide up to 2.1 Gb/s of bandwidth, while the RDRAM memory bandwidth can only reach 1.6 Gb/s, since RDRAM was previously used, the two memories can provide a total of 3.2 G

General statementAndroid apps are limited to the upper limit of memory usage, typically 16M or 24M (depending on the system settings), when the application uses more memory than this limit, the system will be considered a memory leak, was killed. So when it comes to Android, it's important to manage the allocation and use of
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
