What is a service?ServiceService is the software running in the system, this software is mainly to provide a function, then we call this kind of software service1) systemdSystem i

This chapter mainly analyzes the concepts of process definition, state, data structure in the view of code.Definition of the processA process is a running program that is a dynamic executable entity. While a program is a collection of code and data, the code is a static entity that can be used by multiple processes, such as the same application that can run on different computers to produce multiple process

Process Control block: identifier, status, priority, program counter, memory pointer, context data, I/O status information, accounting informationThe process control block is a key tool for the operating system to support multiple processes and provide multi-processing. It can be said that the

fork function in the application, we first go through the interrupt instruction into the kernel state (the x86 schema uses the int instruction, the ARM architecture uses the SWI instruction), and then the system call number to find the Sys_fork function, the final sys_fork function calls The Do_fork function. When the fork function creates a child process, the child process and the parent

A OverviewJava provides two basic process control structures: branching and looping structures. Where the branching structure is used to choose to execute a piece of code based on conditions, the loop structure repeats a piece of code according to the loop condition. The spoke statements have if and switch two, and the loop statements have a for, while, and do and three kinds. In addition to this, jdk1.5 al

today I learned the process control, including a variety of cycles, below are some experience and experience: 1. In the future, we will learn and use the graphical user interface of Java applications, graphical user interface of the operating system or application is the underlying operating instructions in the overall "packaging", such as: With the mouse click menu items, or ultimately to convert to the un

Sequential structuresequence structure of the program: If there is no process control in the code, the program executes in the written format from the top and the next line, and then executes the next statement after the execution of a statement, without judging and jumping to the end of the program.If statementIf statements use a Boolean or Boolean value as the selection criteria, there are three structura
