ruby memory allocation

Java Basics-Stack and heap, static, final modifier, inner class, and Java memory allocation (RPM)Java Stack and heapHeap: Random in orderStack: LIFO (last-in/first-out).The Java heap is a run-time data area in which the objects of the class allocate space. These objects are established through directives such as new, NewArray, Anewarray, and Multianewarray, and they do not require program code to be explici

Memory Allocation in linux: mmap, munmp, brk, mmapbrk Linux virtual memory management has several key concepts: 1. Each process has an independent virtual address space. The virtual address accessed by the process is not a real physical address; 2. The virtual address can be mapped to the physical address through the page table on each process (in the kernel vir

C/C ++ language learning-Memory Allocation Management and Language Learning 1The memory occupied by a C-compiled program is divided into the following parts: 1. stack: automatically allocated by the compiler when the program is running, storing the function parameter values and local variable values. The operation method is similar to the stack in the data struct

What is a heap? When it comes to heaps, I can't help talking about stacks! What is a stack? 1, what is the heap: The heap is a common space, divided into global heap and local heap. The global heap is all space that is not allocated, and the local heap is the space that the user allocates. The heap is allocated during the initialization of the process by the operating system, and can be added to the system during the run, but remember to return it to the operating system or

There are two main differences between static and dynamic memory allocation: First, the time is different. Static allocation occurs during program compilation and connection. Dynamic Allocation occurs when the program is called in and executed. Second, the space is different. The heap is dynamically allocated without s

On Linux systems, when a program is loaded into memory, the kernel establishes code snippets, data segments, and stack segments for the user process address space, which is used for dynamic memory allocation between the data segment and the stack segment. The member variables Start_code and End_code in the kernel data structure mm_struct are the starting and endi

Find from the Internet, see speak is really very detailed, there is no change how much: Slightly changed the organization, and added some content, I hope the logic more clearly If you encounter multiple function calls in the future, then add to the back bar, hehe Turn from: http://biwier.yculblog.com/post.484282.html C + + Memory area allocation Also no @ 2005-01-20 17:36 A.

1. Principle Explanation The Linux kernel uses a memory paging model that applies to both 32-bit and 64-bit systems, and two-level page tables are sufficient for 32-bit systems, and four-level page tables are used in the x86_64 system, as shown in Figure 2-1. The Level four page table is: L Page Global Catalog (page Global directory) L Page Superior directory (page Upper directory) L Page Middle directory (page Middle directory) L Page tables (pag

The great Bill Gates once said:640K ought to being enough for Everybody-bill Gates 1981Programmers often write memory-management programs that are often scary. If you do not want to accidents, the only solution is to find all the hidden mines and eliminate them, hiding is not able to hide.

49965101. Explanation of the principleThe Linux kernel incorporates a memory paging model for both 32-bit and 64-bit systems, and for 32-bit systems, the two-level page table is sufficient, and in the x86_64 system, a four-page table is used, and 2-1 is shown. The four-level page table is:L-page Global catalog (page globally directory)L Page Parent directory (page Upper directory)L-Page Intermediate directory (page Middle directory)L Page tables (page

Memory Allocation Method There are three memory allocation methods: [1] allocated from the static storage area. The program has been allocated when it is compiled, and the program exists throughout the entire runtime. For example, global variables and static variables. [2] Create a stack. When a function is executed, t
