One of the big advantages of Redis over memcached is that it supports data persistence ,One of the most persistent scenarios is to do database use, and the other is to prevent the cache from invalidating when Redis is doing cache servers.The

1. Why should I have virtual memoryIn the early days of the computer, there was no concept of virtual memory. We are going to run a program that will load the program into memory and run it.When you run multiple programs, the following issues often

The fork () function allows the process to copy a sub-process that is almost identical to its own, and the fork function call returns two times:Once in the parent process, once in the child process. Its return value depends on the current process,

Author: LxmuyuLinks: Wait, waitpidWait1.1 IntroductionThe wait function requires a header file:#include #include Wait function prototype:pid_t Wait (int *status);Once the process has called wait, it immediately blocks itself, and the wait

Virtual memoryVirtual memory is a perfect interaction between hardware exceptions, hardware address translation, main memory, disk files, and kernel software, which provides a large, consistent, and private address space for each process. With a

what is socket the socket interface is a TCP/IP network API. The SOCKET interface defines many functions or routines, Program personnel can use them to develop applications on TCP/IP networks. To learn TCP/IP network programming on the internet,

What is SocketA Socket interface is an API of a TCP/IP network. A Socket interface defines many functions or routines that can be used by programmers to develop applications on a TCP/IP network. To learn TCP/IP network programming on the Internet,

1. socket Functions To execute network I/O, the first thing a process must do is to call the socket function to specify the expected communication protocol type. # Include int socket (int family, int type, int protocol); // return: non-negative

I recently read apue. In the process control section, there is a column about two forks to prevent the process from freezing. After some research, I found that the original principle is very simple. The following is an example: 1 #include 2

Connection-oriented socket instance CodeThe server in the instance sends the string "Hello, you are connected!" to the client through a socket connection !". If you run the software on the server and the client runs the software on the client,

We all know that a good way to create sub-processes in Linux is to call the fork function, but many beginners may have difficulty understanding the fork. Let's take an example to see how to use fork. When using fork, remember that fork is" Forks .
