How do I start a programming language? A few tips for beginners

beginner's languageAs Partovi says, Python is a simple language for beginners. Because there is little emphasis on grammar, Python is a language that represents the idea of simplicity. Reading a good Python program feels like reading English. It allows you to focus on solving problems rather than figuring out the language itself.JavaScript is one of the most useful languagesJavaScript is not as simple as python, but it can run on every platform: Mac, Windows, iOS, Android, and more. Every singl

Process scheduling algorithm

first process through a context switch, and the process can sell the CPU (such as blocking) without using a time slice.The advantage of the algorithm is that the time-slice rotation scheduling algorithm is characterized by simple and short average response time.Algorithm disadvantage: not conducive to the handling of emergency operations. In the time slice rotation algorithm, the size of the time slice has a great influence on the system performance, so the time slice should be chosen appropria
