Hello everyone, I am quick-frozen fish 🐟, a front end of water system 💦, like colorful whistle 💐, continuous sand sculpture 🌲, I am a good brother of the next door Cold grass Whale, I just started to write an article. If you like my article, you can follow ➕ to like it, inject energy into me, and grow with me
Read this article 📖
1. You will get a full view of the web by typing the URL to the browser to display the content
2. Get a big picture view of computer networks
3. To understand the computer network from a macro perspective and build a knowledge system of computer network, Yu Yu will follow the new chapter by chapter
4. I am full of interest and hobbies in basic knowledge and cultivate my interest in computer
Preface 🌵
Learning computer network for a long time, I found that the computer network is a very interesting topic, but its knowledge broad and deep, through learning I find that many books are one part of the deep to explain, is to let a person lose interest, from the URL into the browser display picture would allow us to have a comprehensive understanding to the network from zero to one
What is a computer network ⭐
Computer network (English: Computer network), usually referred to as network, refers to the digital telecommunication network that allows nodes to share resources [1]:1-3. In computer networks, computer devices exchange data with each other through connections between nodes (data links). Transmission media can be divided into wired and wireless two types — wired media available to twisted-pair, fiber optic cable and other media [1]:1-4; Wireless is available to Wi-Fi and NFC[2]:4-32.
I look, is not a thief difficult to understand, I also a face meng force. Referring to the computer network, certainly we will think of our daily life with the network to send messages, play games is it, but what is our network, computer network is including two or more computers connected by cable (wired) or WiFi (wireless), for transmission, exchange or sharing data and resources.
Why study computer networks 🌟
The things that seem the dullest and most basic tend to have the longest lives
In the rolling waves of technology, what is the essential thing is our core, that’s right is a network protocol, operating system, database, data structure and syntax, compile principle and other basic knowledge, although our technology development so fast, but the core never out of these things, see the essence through the imagination, we should also learn the computer network.
How to learn computer network 💫
This problem has troubled me for a long time, including the now I am still not very good method, but I have little experience, summed up a little bit of content of computer network, covering wide, theory of many, but not the actual link with us, after watching a lot of books I was also very general understanding of it, until I saw how the network connection of the book, It solved my puzzle that the best way (for me personally) is to understand computer networks from a practical point of view, from our daily working life.
And in learning we will have all kinds of confusion
- There are too many network protocols to remember
- Looks like I do, but I can’t stand the question
- Knowledge learned, but not practical application
Above all, I have encountered, I found the best way, is to start to configure the network, buy a server to build, their own hands to configure CDN, to buy domain name, DNS configuration and so on. Combining theory with practice is the best way to learn.
Of course have a complete understanding to the network, can let us better to learn the computer network, I think we can’t a plant into each piece of knowledge, so that we harvest is rather small, we should from the direction of the wide to understand the whole process of computer network, and our life together, have a comprehensive understanding of, I believe that only in this way can I learn computer network well. This is why I want to write this column. More is to supervise myself to complete the knowledge sorting of computer network and establish a knowledge system.
Full picture of the network 🌊
Knowing the whole picture of the network can help us learn better
Road map of discovery 💻
Network communication process
- Browser generated messages
- Transmission of TCP/IP data using electrical signals (optical)
- From network cables to network devices
- Access the Internet through an access network
- Server-side LAN
- The request arrives at the Web server and the response is returned to the browser
Generally speaking, we write a letter on the computer and need to send it to a distant friend. First, the letter will be wrapped and sent through the computer, that is, through the network cable, and then through the Internet, to the Web server, and the Web server responds in the same way.
Conclusion 🍁
This article is just a start for this column, and I will update this series of articles next. I hope I can stick to it and summarize every link in the form of article output, which is not only convenient for me to consolidate network knowledge, but also let you read this article can gain

Conclusion 🌞
So my “from the URL to the web page 🌏” build a knowledge of computer network system – 01 was over, actually very simple, the purpose of the article is the summary of daily work and output, output some feel useful to everybody, food not food is not important, but love 🔥, hope everyone can like my articles, I am really very attentively in writing, Also hope to know more like-minded friends through this article, if you also like to toss, welcome to add my friend, sand sculpture, progress together.
