IoT Journey with Arduino - From Arduino Beginner to IoT Intermediate!

Automation gives freedom to people's daily lives. Experience how technological advancement can affect people through automation. This lecture is the second in the Life Arduino series.

You learned Arduino, but don't know what to make with it? This lecture is the first in the Arduino application series, and you can learn about the synergy between Arduino and a 3D printer. However, you don't necessarily need a 3D printer.

Many people use Docker, but few understand its underlying principles. Without understanding these principles, you can only rely on searching for answers when problems arise, rather than solving them yourself. The essence of Docker lies in the operating system. This course is not a superficial overview of memorizing a few commands; it delves deep into the inner workings of the operating system that makes up Docker. Once the internal structure becomes visible, Docker is no longer difficult.

If you want to work for a long time as a super developer who can handle the entire process of service development and operations alone, building a solid foundation in IT infrastructure knowledge is just as important as learning various programming languages!

[Introduction to Security Incident Response: Learning through Scenarios of Web Server Hacking, Ransomware, and Account Takeover] This course examines why various information security incidents—such as web server hacking, ransomware, account takeover, and internal penetration—occur and how they spread, categorized by incident type. Students will follow each incident scenario to understand the attack flow, analyze the core causes of the incident, and learn how to resolve issues and prevent recurrence through security architectures such as firewalls, DMZ, access control, privilege management, backup, and log monitoring. Rather than a simple explanation of security concepts, this is a scenario-based introduction to information security that provides a comprehensive understanding from root cause analysis to resolution strategies.

This is Part 1 of a roadmap lecture that concisely organizes the essential computer science (CS knowledge) needed to excel in development and data, in a short period. This lecture has also been used as an in-house lecture at top domestic companies for several years. Based on 20 years of experience in actual practice, from system SW to web, app development, and data science, this lecture systematically yet easily organizes the essential core knowledge needed to excel in development and data.

Learning about various communication techniques and understanding their differences helps you develop the ability to select and implement the most appropriate communication method.

This is a course to comprehensively understand 5G networks. We will look at the evolution from 1G to 5G and learn about the characteristics and architecture of networks including 5G RAN and 5GC.

The most difficult thing when malware is distributed is script obfuscation. Understand the obfuscation technique and analyze the malware executable file that is distributed after decrypting it.

This course is designed to guide those who have completed the "Mastering Core Network Theory through Memorization: Basic Course" to understand more advanced theories. It covers deeper concepts such as NAT technology, which is the operating principle of internet routers, as well as load balancing system principles and VPN technology principles. The goal of this lecture is also to finish by "memorizing" it all! You can do it!

Learn the core HTTP features essential for practical use and how to design proper HTTP APIs.

This course covers essential content that C# application developers with 0.5 to 3 years of experience must know.

Building a smart factory is difficult with theory alone, isn't it? I will show you how to apply it in the field using the IoT and SCADA practical know-how I've experienced firsthand.

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.

Learn I/O, networking, reflection, and annotations in depth, from the basics to the practical level. Build a web application server (WAS) directly in Java.

New to Arduino but want to get certified? A current university professor and 4th Industrial Education expert with 20 years of experience will personally lead you to passing the Level 3 exam. From circuit connections to coding, we break down complex concepts easily using real-life examples.

How do the sites we access every day work? Before we start studying data in earnest, let's take some time to learn about servers and the Internet, which are the background knowledge of IT.

This course aims to understand various security threats occurring in information systems, particularly in internet environments, and to learn core security technologies to protect against them. Focusing on key cryptographic techniques such as symmetric and asymmetric key cryptography, the course is structured to provide a systematic understanding of the overall flow of information security, including the underlying mathematical concepts of cryptography.

This course proceeds in stages where you learn and apply necessary knowledge while building infrastructure, similar to real-world practice.

Learn about the network multiplayer framework, also known as the other Unreal Engine. Learn the key concepts, inner workings, and optimization techniques you need to know when creating a network multiplayer game, then create a hack & slash type PvP battle game.

This course covers the basics of Amazon EKS, an AWS-managed Kubernetes service, designed for beginner Amazon EKS users.

It goes without saying that AI artificial intelligence is the trend. But what can you use machine learning and deep learning for? Now, let's learn useful Internet of Things IoT Computer Vision projects that are used in daily life.
