No 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~~

Wow, 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.!!

The instructor's explanation is simple and easy to understand! I've studied networks before, but at the time, the explanations were difficult and there were many parts that were hard to understand, so I was worried when I bought the course, but it was really a needless worry. ㅎㅎ I recommend it to friends who want to study networks! Even concepts that I've forgotten for a long time are easily explained by the instructor, so they stick in my head. ㅎㅎ I really recommend the course!!!!
You can understand communication theory and the Physical, MAC, Network, and Transport layers for configuring wired and wireless computer networks.
We use the Packet Tracer program to learn how communication theory is actually applied to computer networks.
We will configure an integrated network that combines wired and wireless networks and learn about the various protocols used in it.
You can learn about the protocols that make up a network in an easy-to-understand way.
Let's build your confidence in networking through theory and practice with NetGyver, a PhD in Computer Science!
💪
This course covers the theory of various protocols operating in computer networks and provides immediate hands-on practice using Packet Tracer. It is designed not only to deliver fundamental and basic network knowledge but also to include content that enables you to directly configure and verify simple networks.
In today's environment where every device is connected to a network, if you have an IT career, you must have an understanding of networks. Computer networking is not an option, but a necessity.
The lecture content is updated. When you take the course, you have the advantage of being able to listen to additional content without paying any extra fees. It could be network technology or questions for verifying your skills.
The reason I created this course
While studying computer networks, I found it difficult to understand how protocols are actually used when relying solely on theory. Especially when handling equipment in the field, there were times when I felt lost regarding how protocols actually operate. That's why I created this course—with the idea that it would be much better to practice related concepts immediately after studying the theory.
Section 0. Preparing Packet Tracer
Learn how to obtain a Packet Tracer license, install the program, and 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
Take a detailed look at the essential theories of computer networks.
Section 3. Network Configuration Using Simulation
Learn about the devices and protocols that make up a network and proceed with hands-on practice.
Section 4. Integrated Network Design/Implementation/Verification
Design, implement, and verify an integrated network based on everything we have studied together so far.
Frequently Asked Questions (Q&A)
Who is this course right for?
Those who want to understand integrated wired and wireless network structures
Those who want to try configuring a network using network equipment
Those who want to accurately understand the communication theories of computer networks through hands-on practice.
Those who have learned networking theory but still don't quite understand it.
Need to know before starting?
No prior knowledge is required. Anyone with a passion for learning and a commitment to consistent effort is welcome.
The well-explained lecture materials are a bonus~~ ^^

This 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~~!!!
I sincerely thank you for helping me with my lecture. I hope you have a wonderful career ^^;
