Operating System-webpage storage management and operating system storage
When talking about page-based storage management, I would like to talk about the user's program first, because page-based storage management serves the user's program or processes. After a program is compiled, it will definitely occupy space, that
CookiesCookies, sometimes in their plural form, are the data (usually encrypted) stored on the user's local terminal by certain websites in order to identify the user and track the session. The next step is to talk about some of the advantages and disadvantages of cookies, cookie although the persistent preservation of client data provides the convenience of sharing the burden of server storage, but there are many limitations.First: Generate up to 20
Memory partitioning, memory allocation, constant storage, heap, stack, free storage, global zone [c++][memory management] [reprint]A. In C are divided into these storage areas1. Stack-the release is automatically assigned by the compiler2. Heap-usually released by the programmer, if the programmer does not release, the program may end up being recycled by the OS3
In the actual development, the storage data is mainly using SQLite. In practice, we mainly use the following three kinds of storage methods.(1) using plist storage to simply NSString, Nsarray, nsdictionary, etc.(2) Using preference storage, similar to the above, the storage

Sessions and cookies are not just a store on the server side, a general
Although the session is stored on the server side, but also needs to match with the client, imagine a browser why
a queue is a linear table that allows an insert operation at one end only, while a delete operation at the other end (insert operation at the end of the queue, delete on the head) . In contrast to stacks, a queue is a Advanced First Out linear table (first in first out, FIFO). The same as the stack, the queue is also an important linear structure, the implementation of a queue also requires a sequential table or linked list as the basis. Chained storage

Brief Introduction:
1, Docker 1.12.6/v17.03 documents in the CENTOS7 system installation, clearly stated that for production, must use the Devicemapper-driven DIRECT-LVM mode, we need to prepare the block equipment in advance to provide better stability and performance. The Devicemapper-driven LOOP-LVM mode is used by default because the installation is simple and applies only to test environments. As can be seen from the Docker info information, the maximum available space for LOOP-LVM mode is
Storage management is divided into continuous and discontinuous storage, and discontinuous storage is divided into paging storage, segmented storage and Segment-page storage. Paging storage
Available page caches include Http Cache, Local Storage, Session Storage, and Application Cache. they can be used to reduce the number of requests to improve page performance and reduce traffic consumption, which is more important for mobile browsers (In addition, Memory Cache, but it is transparent for front-end projects ).

The tenth chapter is about the principle of self-compiling.Storage organization when the target program is runningLogically, before the code is generated, the compiler must design the environment of the target program and allocate the data space. When the program is running, it needs to get a piece of memory to run on it, which needs to contain the target code and the data space
