Operating systems are an important part of almost all computer systems. Computer systems can be roughly divided into four parts: hardware, operating systems, applications and users. The basic purpose of a computer system is to execute user programs and solve user problems more easily.. To achieve this goal, a computer hardware is constructed. Because hardware

Operating system kernel (linux), operating system kernel linux Kernel of the Operating System) Is a group of programs that focus on managing all activities of the computer and all hardware in the drive

Running a virtual machine on Windows is a Linux operating system, how can you pass files between different operating systems?This is my personal firsthand, assuming you do not have a good method. It was very painful indeed. Here is a summary of my personal approach: method One. Very useful:* * * * Using a winscp software, it is an open-source g

Operating System: management process understanding, operating system management process understanding I recently started to read the operating system book (which is not in this direction). I still cannot fully understand it when I

that the operating system remain unchanged in terms of user interface and programming interface. How to better organize and schedule tasks so as to maximize the performance of the CMP structure is the core issue, which is the greatest expectation of CMP. To solve this problem, software and hardware must work together to start from task scheduling, interrupted allocation, and resource sharing, in terms of h

Solve_fork1 () {while (lock==1) {} cnt++; printf ("%d has entered the critical section \ n", Getpid ()); lock = 1; } void Solve_fork2 () {while (lock = = 0) {} cnt++; printf ("%d has entered the critical section \ n", Getpid ()); lock = 0; } The above is achieved mutex access is not wrong, but also problematic, first of all, he was busy to solve the problem, and secondly, he can solve two of the process of competition.

UNIX is a very popular network operating system. Using the Domain Name Service function provided by UNIX, it establishes a Domain Name System for the Enterprise Intranet, which can effectively manage the network, it is convenient for users to operate Internet tools such as e

It's just picky who its friends are. 1. Introduction to file systems and permissions For a Windows user, the first entry to access Linux should be the ext file system permission. Unix-like opera
