This September to find a job, inadvertently see a blog, think of the knowledge points in the summary, consolidate the basic knowledge, to find work to do some preparation:Overview of the Java memory model http://blog.csdn.net/pistolove/article/details/46753275 Java memory model Inter -memory interoperability

Shared memory is the most useful method for inter-process communication and the fastest IPC format. The shared memory of two different processes A and B means that the same physical memory is mapped to the process address spaces of process a a

In recent years, vulnerability mining has become increasingly popular, and various analysis articles on vulnerability mining and exploitation have e
Memory leak refers to a situation in which a program fails to release memory that is no longer in use due to negligence or error, and is a waste of memory because of a programming error that causes the JVM to lose control of the memory because of a program failure. A general memory
OverviewThere is a high wall between Java and C + + that is surrounded by dynamic memory allocations and garbage collection techniques, and people outside the walls want to go in, but the people inside the wall want to come out.For developers engaged in C, C + + program development, in the field of memory management, they are the highest power of the emperor is the most basic work of the working people-the
What: What is dynamic memory?In C + +, the normal variable (non-static object) is stored in the stack memory, static variables (local static, class static) are stored in static memory, there is another memory pool in the system, this part of the memory for the program to all
Hyper-V does not support memory overcommitment, and has been criticized by VMware and other virtualization vendors. Of course, Microsoft has been denied that this is their weakness, that in order to ensure the production environment VM performance, excessive allocation of memory is inappropriate. But Microsoft's attitude seems to have changed abruptly, March 18, in its Virtualization official blog published

The amount of memory that SQL Server consumes has been increasing since startup:First of all, as a mature product, the chances of memory overflow are negligible. Learn how SQL Server coordinates and shares
Children's shoes, which have been programmed with C language, must know something about dynamic management memory. That's not much of a benefit. Dynamic memory management for STM32 todayMemory management refers to the technology of allocating and using computer memory resources when the software is running. Its primary purpose is to efficiently and quickly alloca

Recently began to want to learn a little bit more about the Linux kernel, the main reference is "deep understanding of the Linux kernel" and "deep understanding of the Linux kernel architecture" and the source code, experience is limited, can only analyze the limited content, read this after more in-depth study.1, memory addressLogical address: Contains the address used in machine language to specify an operand or an instruction.Linear address: A 32-b
