How an Operating System Works

How the operating system works Windows XP is preinstalled on the purchased desktop or laptop. Macintosh computers have OS X preinstalled. Many enterprise servers use Linux or UNIX operating systems. The operating system can also be found on smaller devices. For example, it is a mobile phone. The purpose of the operating system is to organize and control the hardware and software. Controls PC, hard drive, memory and so on. In a simpler system such as a mobile phone, the operating system can control the connection to the keyboard and battery, or service provider.

All these "organs" are managed by operating systems such as Windows and Macintosh (Mac). According to Curt Franklin and Dave Coustan of "How the operating system works", "The purpose of the operating system is to organize and control the hardware and software so that the laptop operates in a flexible and predictable manner ". A program that is running is always important because it constantly competes for CPU attention. The operating system allows the CPU to provide the necessary resources for each program. The operating system also includes a consistent application programming interface (API) that can write software on a laptop, transfer / download to another laptop, and work as intended by the programmer.

This document provides answers to the following questions. How does the operating system work? How does the boot loader work? What also prevents Web browsers from accessing core system files? How does the CPU manage multiple running programs at the same time and each program needs multiple threads of execution? It is difficult to tell how useful this is for everyday programming work, but it is still very useful text.

I used to work on the operating system before. In fact, since the operating system is a relatively time-consuming technology, relatively speaking, there are not many practitioners and many people tackle the TCP / IP stack. I do not think everyone is talking about block chains today. Absolute number of block chain talent is missing. However, in general, there should not be so many people developing block chains. I have studied many block chain techniques, but most of them do not make sense.

Chen Rong answered Feng Wang's 10 questions - Why do I insist on building a block chain operating system?

The initial goal is to have a system and method of work to learn the basics of business. I like to use the system. To achieve this type of surgery, people need to have the skills they need to do the job. In basketball, it is ball handling, footwork, passing by, and spacing. In the business world, you may use operating systems and other forms of communication. This brings in the process of doing business, a language connecting people and colleagues. Simple but effective
