Linux overview Linux is a free-of-charge and freely-spread Unix-like operating system. it is mainly used on computers based on Intelx86 series CPUs. The core program (kernel) that controls the basic services of the entire system is developed by

I have been researching a new development model over the past few days. So I will post it for you to share. Use open-source LAJP technology. Purpose: Verify the two Kingdom languages JAVA/PHP). Different Languages and mechanisms are combined. PHP is

In linux inter-process communication, message transmission is divided into pipelines, FIFO, and message queues.(1) PipelinesThe pipeline is created by the pipe function and provides a single (one-way) data stream. The pipe function returns two file

Unix File System OverviewEvery process in Unix has a current working directory.To identify a specific file, a process uses the pathname. If the first character of the pathname is a slash, the path is the absolute path, and its starting point is the

This paper mainly introduces four kinds of methods to realize shared memory synchronization.Shared memory is the most efficient way to communicate between processes, and processes can read and write directly to memory without requiring any copy of

Inter-process Communication overviewInterprocess communication has the following objectives:1, the data transmission, a process needs to send it to another process, the amount of data sent between a byte to a few m;2, sharing data, multiple

What is LinuxThe same set of operating systems cannot be run on a platform of different architectures.Refer to the HARDWARE function function and modify your operating system program code, the revised operating system will be able to run on another

Linux is a set of free and open source Unix-like operating systems, born on October 5, 1991 (the first officially announced), by the Finnish students Linus Torvalds and later joined the many enthusiasts jointly developed.Linux is a POSIX and

I. INTRODUCTION there are two main types of message queues: POSIX message queues and System V message queues. System V message queues are currently widely used. Considering the portability of applications, newly developed applications should use

Generally speaking, there are two different initialization methods for Linux/Unix systems. 1) BSDsysteminit2) most of the distribution kits of SystemVinit use the init, which is similar to SystemVinit, that is, SysVinit... Generally, Linux/Unix

Unix shared memory highlights shared memory advantages: 1. fast and efficient data transmission between processes without passing data through the kernel, that is, copying data without calling the system. 2. as the kernel continues * nix shared
