• Summary of Java Core Technology
  • HTTP Summary
  • The Basics programmers Need to Know
  • Summary of Operating Systems

These four PDFS can be said to be one more hardcore than the other.

Let’s start with a summary of Java core technology

Summary of Java core technology

Take a look at the mind map for this article, which is organized around the following.

 

This PDF can be used as your introduction to Java development manual or as a great tool for finding gaps

 

 

HTTP Core Summary

The second PDF mind map

 

You can look at the drawings inside, it’s really hard work.

 

 

This PDF covers almost 99% of all HTTP information

 

Core knowledge programmers must know

In today’s world of iterative technology, you can’t learn fast enough to keep up with framework iterations, and Spring 5 came out when you were still learning Spring 3. Also, there are so many people who know how to use Spring these days that they are studying how the new technology works and how the framework works, but forget why it was designed and how it works. So, the basics are the most important thing, computers only know zeros and ones a few years ago, they still only know zeros and ones, so you have to spend a limited amount of time on technology that doesn’t change. The basics are immutable, and change is fine-tuned, not overturned. So, I’ve written a PDF of my own, a programmer’s must-know, to tell you about these unchanging fundamentals.

I took you to understand what the CPU is, what are the CPU registers

 

 

Let me talk to you. What is memory

 

I have very carefully summarized for you the principles of binary computing in computers

 

I’m going to talk to you about how disks came into being, how they evolved, why they can store data.

 

Summary of operating system

This is the most hardcore PDF I’ve ever had

directory

 

The operating system is so important, you can say that without the operating system, there is no one to tell you so much. So it’s important to get to know the operating system.

This PDF takes you through some of the core concepts of the operating system to give you the big picture.

 

This PDF takes you from the beginning to an in-depth understanding of the core abstractions of the operating system:

Process, file, address

 

 

 

Also summarized for you the operating system core interview questions, to help you

 

This PDF is 306 pages, 17W words, I think this should be the first operating system PDF in the whole network, I hope you can treasure it.
