After the experiment of lab1 is completed, start lab2, which mainly realizes memory allocation Purpose of the experiment: Understand the translation mechanism based on segment page memory addressUnderstand the establishment and use of page tableUnderstand how to manage physical memory In lab1, we use segment management, and the addresses inv ...

Implementation of process scheduling algorithm Summary: The process scheduling algorithm is realized, including FCFS (first in first out), SPF (short process priority), HRRF (highest response ratio priority method) and HPF (priority method). A process management simulation system that allows n processes to run concurrently is designed. The syst ...

Programming environment: Ubuntu Kylin 16.04 Code warehouse: https://gitee.com/AprilSloan/linux0.11-project linux0.11 source code download (it cannot be compiled directly and needs to be modified) 1. Add kernel After entering the kernel, it does not immediately enter the main function. In the previous chapter, gdt is only set temporarily. In ...

This article is taken from WeChat official account GitPython: Ten common Python automation operations . In case of infringement, the contact must be deleted. 1. OS module Import: import os 1. Traverse the folder The premise of batch operation is to traverse the folder, OS Walk traverses the folder and generates three parameters: Current ...

I've been reviewing the operating system recently, and I have the following knowledge points: 1) Process scheduling algorithm: it adopts os scheduling algorithm (i.e. assigning the processor to the process with the highest priority) and first come first serve algorithm. 2) Each process is represented by a process control block (PCB). The proce ...

1, Basic command 1.1. Startup and login Boot will start many programs. They are called "service s" in Windows and "daemon s" in Linux. After successful startup, the text login interface will be displayed, which will not be displayed when entering the password. Generally speaking, there are three ways for users to log i ...

Linux as a general hardware kernel, how to achieve general and efficient memory management. In the previous article on Linux memory segmentation and paging, we mainly explain that the Linux kernel carries out the abstract mapping of physical address, logical address and linear address, which is like dividing territory for families in a wilderne ...

I recommend a free open course of zero sound college. Personally, I think the teacher speaks well. I share it with you: Linux, Nginx, ZeroMQ, MySQL, Redis, fastdfs, MongoDB, ZK, streaming media, CDN, P2P, K8S, Docker, TCP/IP, collaboration, DPDK and other technical contents, learn immediately 1, Use of conditional variables API s related to c ...
