The story of a non-network expert
cjcho
This lecture is written from the perspective of a non-major, so it may be lacking. However, as a non-major, I may know better what is difficult to understand.

Easy-to-understand computer networks from someone with 20 years of experience
Learn the theory of computer networks. Study networks thoroughly by configuring your own network using a simulation program. We provide lecture materials with good explanations.
Reviews from Early Learners
What you will learn!
You can understand the communication theory and Physical, MAC, Network, and Transport Layers for configuring wired and wireless computer networks.
Learn how communications theory is practically applied to computer networks using the Packet Tracer program.
We will configure an integrated network that integrates wired and wireless networks and learn about the various protocols used in it.
You can easily learn about the protocols that make up a network.
Through computer network theory and practice
Let's build networking confidence! 💪
This is the first lecture in the "Complete Network Conquest" roadmap.
Lecture Topic
This course covers the theory of various protocols operating on computer networks, and includes practical training using Packet Tracer to impart basic/fundamental knowledge about networks. It also includes related content so that you can directly configure and verify a simple network.
Why should I learn?
In today's environment where every device is connected to a network, an understanding of networking is essential for IT professionals. Computer networking is not an option; it's a necessity.
Why is the course period unlimited?
We're updating our course content. By taking the course, you'll benefit from access to additional content without paying extra. This could be networking skills or a skill-testing exercise.
Why I Created This Course
While studying computer networks, I found it difficult to understand how protocols were used if I only studied the theory. Especially when working with equipment, I often found myself confused about how protocols worked. So, I decided to create this course because I thought it would be much more beneficial to study the theory first and then apply it directly to practical application.
💡 Course Features
Explains the essential theory.
We explain only the simple and essential parts in an easy-to-understand manner.
• Explains the core parts of network essential theory in an easy-to-understand manner.
• We did not cover technologies that are no longer in use, reflecting the latest technologies.
• After fully explaining the principles and core concepts, we will practice them using Packet Tracer.
• The exercises are designed to be easy to understand and follow, even for beginners.
📜 Brief introduction to the curriculum
Section 0. Preparing Packet Tracer
After obtaining a Packet Tracer license and installing the program, learn how to use it.
Section 1. Introduction to Computer Networks
Learn what a computer network is and what its components are.
Section 2. Essential Computer Network Theory
Learn more about the essential theories of computer networks.
Section 3. Network Configuration Using Simulation

100% enrolledWow, it was tough. Really, really.. It's a great lecture. I used to study networks by myself and struggled with them, but I felt like things weren't organized, but after listening to this lecture, I was able to organize my thoughts on networks well.! I have a question. I wonder if you are producing a separate lecture on network security.! I definitely want to find this and listen to the instructor's lecture. I learned a lot. Thank you.!!

79% enrolledThis is such a great lecture! I just got a job and I'm doing network troubleshooting, but my knowledge about networks was fragmented and not smooth, so it was so hard. I've been secretly hoping that Inflearn would upload a lecture like this. I signed up for this lecture as an early bird as soon as it was uploaded, and I felt like a stream was being created through this lecture! I felt like I've grown since before I took it, combining what I learned in undergraduate lectures with the situations I've experienced in practice!!! Absolutely!! If you can give me a roadmap for networks, I'm confident I can take all the lectures!!!!!! I've taken a lot of lectures, but among the lectures I've taken through Inflearn, this is the one that I don't regret spending money on. Strong recommendation~~!!!

45% enrolledNo matter how much I read the network book, I couldn't understand it, but through this lecture, I started to understand it. The only downside to this lecture is that I get impatient waiting for the next lecture. Please open the next lecture quickly~~
