Many readers have asked me how to learn an operating system. How many books do you recommend for your operating system? What do YOU need to learn about operating systems? Are there any videos I can watch? Below, I will make my own elaboration on these problems.

Learning operating systems is not so you can design an operating system, but so you can better understand how it works.

If you find the operating system a bit difficult, I highly recommend taking a look at my PDF.

Programmers must know the core basics

This PDF gives you a basic introduction to computer hardware and how it works.

This PDF can be said to be applicable to any small white, if you can read, you have a certain basis, can formally enter the operating system.

I learn operating system is according to the China Machine Press “modern operating system” the fourth edition of learning. I read it according to the Combination of Chinese and English, you may be confused after reading it, but it doesn’t matter, just one sentence is very important.

Take 200-300 hours to get started on a subject, and then review the essence of it at intervals throughout your career

Operating system concepts and questions

If you’re still struggling with the basics of what computers need to know, take a look at my list of core operating system concepts

I wrote an operating system dictionary for you!

And the operating system interview questions for you

By the end of this article, you’ll have no problem arguing with the interviewer

Operating system learning materials

The open source project

First of all, I recommend a very good open source project

Teach yourself Computer Science

Not only will you find resources related to the operating system, but you will also find other resources related to the computer black book

One sentence in it was very refreshing

If you are a self-taught engineer or graduated from a programming class, it is essential that you study computer science. Fortunately, you don’t have to spend years and money on a degree: you can get a world-class education on your own.

Why do some people say it is not necessary to learn computer basics? Now it seems impossible

There are two kinds of software engineers: those who understand computer science well enough to be able to tackle challenging creative work; The other makes do with mere familiarity with some advanced tools.

Both groups call themselves software engineers, and both earn similar salaries early in their careers. Over time, however, the first type of engineer grows and does more meaningful and better-paid work, whether it’s valuable commercial work, breakthrough open source projects, technical leadership, or high-quality personal contributions.

Recommended on the operating system website

I’d like to recommend some of the websites that I refer to a lot in the course of operating systems

Generally few people recommend operating system websites… These sites are from my usual learning summary, and some are from excellent answers on the Internet. I hope these sites can help you have a deeper understanding of the operating system.

studytonight

Studytonight is awesome!! Studytonight will include the Operationg system, but it is not to say that studyTonight is a pure OS learning website, it is a basic tutorial website, its home page is not limited to OS, It also includes Java, C, CSS, OS, Computer Network, etc.

This page fell in love with a look, and a lot of domestic pages do hard style is different, such a tutorial is not so stiff and annoying. There are all kinds of tutorials in all the materials

We recommend the operating system, so just go to the operating system home page, and that’s what it looks like

Studytonight is a friendly site for beginners to learn operating systems.

The course art is mainly divided into three parts, from easy to difficult, which are the basic part, the medium part and the improving part respectively. We click on the first part of the basic part

Use simple descriptions and pictures to make it clear and purposeful, and these topics can also be used as interview questions

Ll: That’s right. Studytonight does have interview questions

We’ll find a lot of interview questions under the Test TAB

After we choose Operating System, we will find many tests

Is an integrated learning platform, suitable for novices, I roughly looked over, there is more basic things, a wide audience, is a necessary website for everyone to learn.

udacity

Udacity is a video learning site with a clean-looking interface.

There is also an introduction to the course below, and you can also start the free course. This interface is a Chinese version, which is very impressive

My courses are all the courses you’ve taken, and you can search for specific courses in all the courses, so there’s a lot of different kinds

Let’s take the operating system as an example and look at the specific course

On the left side is the list of specific courses, and on the right side is the lecturers teaching part. The video is very clear, and the lecturers speak clearly, which can practice English. Some friends said that they could not understand English, and retreated to the English network, which is not a good habit. The importance of English in the programming world is self-evident. So English is a language you must learn well.

The lecturer still has specific practice link after finishing the course, consolidate as study, very good.

Udacity is a little deeper than StudyTonight. The operating system course is divided into 22 classes, with many sections in each class. It’s a great site. I am writing an article now, I have to write, study at once! . Or hold back, that finished writing immediately to see!!

tutorialspoint

Tutorialspoint this site is also a resource tutorial network, this site’s search index is very high, basically any search questions have tutorialspoint explanation.

After we click into Library, we find that this is a treasure trove of tutorials, listed very clearly

Tutorialspoint also offers video tutorials, though most charge for them.

There are many tutorials, not only for programming, but also for Excel, SAP, etc.

Tutorialspoint also has e-book tutorials, but most of them are also charged, should be tutorialspoint’s own production of PDF, I do not know how to write, if interested in friends can pay to download, remember to send me a copy of oh, hey hey.

With all that said, we haven’t even looked at the home page of the tutorialspoint operating system

Left is the navigation bar, right is the specific tutorial, this style feels a little old, but the classification is very clear, inside the content is worse than StudyTonight, is also a very good start tutorial network

classcentral

The classcentral website is a bit of a strong one

We found a Chinese tutorial, a look is the tutorial of Nanjing University, Nanjing University is also a very cool school, xiaobian also has gay friends in The South University in film and television, in fact, I am a programming delay director, dog head to save life.

All right, let’s take a look at the nTU course

The discovery of so many excellent courses in Chinese universities also shows the status of Chinese universities in the world. Overview is an Overview of the OS.

After registration, we click “Start the course” and enter the lecture page

The course is divided into 6 weeks in the form of video and we begin with an overview of computer systems.

Finally can see the operating system that compatriots speak!!

On the right side, you can take notes and view them at any time. The course also supports downloading, which is very nice!

Well, it’s time for us to quit. I can’t help listening again!

nptel

As if to see a great website, the name of this website faint feeling a little cattle force. Let’s see where it is, and then why it is

Can you tell it’s awesome?

Each of these directories is a fucking book, and it’s not a lot of pages, but it’s a real treasure.

From an operating system overview to file systems, process management, file management, I/O management, and much more. This is not the most awesome, the most awesome is the right side can download for free, you said annoying people

You can download PDF versions of each chapter.

With curiosity, we clicked On About Us.

Then came the following

That is to say, it is an Indian National Enhanced Learning program, that is, a free learning program jointly offered by the major universities in India, which explains why Indians are getting better at electricity, programming, communication.

This is a site you have to check out. I think it’s on a par with the black book series.

codescracker

Codescracker is another awesome website, after reading this website, I think low-key is the best awesome show off…

The categories are pretty thorough and the explanations are pretty good, but Codescracker isn’t just an OS site, it’s a one-stop platform for learning a programming language, but it’s pretty simple

You can see that there are a variety of tutorials, and there are test classes below, covering almost all the languages used by the enterprise.

A website you must treasure.

sciencedirect

This website, ScienceDirect, is awesome. Baidu’s explanation of ScienceDirect

However, most of scienceDirect’s PDF downloads are available for a fee. Interested parties can purchase them

homepage

What does a Homepage do

This is a computer science and statistics website, and then we click on Search to search OS directly to the OS website

Then hehe hehe, this website is quite strange, it has no back and forward button, that how to access?

I was directly through the url to access, the home page is homepage.cs.uri.edu/faculty/wol…

But the site is too hardcore, a good learning material.

computer.howstuffworks.com

Computer.howstuffworks.com is a computer web site, it covers all aspects of software and hardware.

Computer knowledge includes Computer hardware, networks, Computer software, Computer secrets, and so on

These are very well written articles. It’s an encyclopedia of computers.

As usual, if we click on the topic of COMPUTER OPERATING SYSTEMS, we can see that there are some very good articles

Add favorites!

tldp.org

This site is another awesome site for learning operating systems, I don’t know how many times I’ve said this tonight, hahaha.

Let’s see what the home page looks like

This looks like a great site, don’t ask me why, OS page is like this

Without any embellishment or decoration, adult life is so unpretentious.

bilibili

Speaking of tutorials, how can there be no big B station for me?

YouTube says, “Bilibili, stand up,” and Bilibili reluctantly says, “Why?” “You stand up,” YouTube says, and Bilibili reluctantly stands up. Youbute then says: “Nothing personal, everyone here is rubbish!”

Put forward the errata

Finally, a few errata that I personally and readers have found. To err is human, but there are mistakes or to point out, so as not to encounter the same problem nonsense, both a waste of time and no effect, not to see the original English words it is difficult to find problems.

Note: If you find any errata in the process of learning, please add my wechat lX252279279, I can help you feedback.

The last

Finally, AT the end of this article, I would like to recommend the OPERATING system PDF compiled by myself, which can be viewed offline. It is 306 pages in total, with about 50W words, beautifully typeset and very clear. I typed the words one by one and drew the pictures one by one.

In addition, yesterday, a university teacher also approved my PDF, which is also a recognition of me. I didn’t expect it would have such a great social effect.

You can follow my official account Java Builder or scan the qr code below and reply to OS to obtain this valuable PDF.
