Learn assembler

Secure Coding in C covers concepts such as buffer overflow, memory management, and vulnerability prevention to ensure the development of safe and reliable software applications.

This course is designed to prepare you for the Information Processing Engineer practical exam solely through solving previous exam questions. Instead of unnecessary theories or vast amounts of content, it focuses on past exam questions that are repeatedly featured, allowing you to connect your learning directly to passing the exam. You can quickly grasp core points and question patterns by reflecting on the latest trends, and even learn tips for writing answers through the problem-solving process. This lecture is optimized for examinees aiming to pass efficiently in a short period of time.

This course contains only the essential content about C, the basic language of all languages. It is recommended for those who are learning C for the first time.

After studying the operating principles of computers, C language syntax, and application methods through Hong Jeong-mo's 'C Programming: Learning by Doing,' this course will naturally bridge you to the subject of Data Structures from a programming perspective. It will serve as both C language practice and a way to instill the core concepts of data structures into your mind.

Software quality is a habit! This course will teach you how to become the best programmer that companies want.

This lecture covers how to properly implement a linked list-based linear data structure using C language. You can understand the structure of the DB as well as the linked list at once.

Pass the Engineer Information Processing Practical Exam on your first try! We’ll pinpoint only the essential code and theory you need to know. Master past exam questions completely! Open the door to success with systematic lectures. 🏆 2024 Inflearn Rookie Newcomer Award 🏆 2025 Learners’ Pick Award

This course aims to help learners who are new to ESP32 and IoT development master everything from environment setup and language basics to hardware control and RTOS utilization. The main objectives of this course are as follows: - Acquire the ability to use the ESP32 development environment and basic tools - Understand the C language and ESP-IDF structure - Understand FreeRTOS tasks and basic synchronization methods - Enable hardware control through GPIO, I2C, SPI, and UART - Understand storage and memory structures and implement simple persistent data storage

This is a lecture on 'Data Structure and Practice' by Professor Kwon Oh-Heum of Pukyung National University. You will learn about data structures through examples and practice using C.

This course is designed for learners who have mastered the basic development methods of the ESP32 to progressively study low-power design → Wi-Fi networks → REST APIs → Web Servers → MQTT → OTA → Bluetooth BLE, with the goal of directly implementing the communication functions required for real-world IoT devices. The main goals of this course are as follows: - Understand and utilize low-power features of the ESP32, such as Light Sleep and Deep Sleep - Configure Wi-Fi Station/AP modes and handle network connections and exceptions - Implement communication with external servers using HTTP/HTTPS and REST APIs - Configure a Web Server and WebSocket server within the ESP32 - Host websites and React-based UIs directly on the ESP32 - Implement MQTT-based Publish/Subscribe communication - Perform remote firmware updates and version management using OTA - Understand the GAP/GATT structure of Bluetooth BLE based on NimBLE and implement Server/Client functionality

A must-take course for anyone thinking of becoming a Windows programmer! Have you studied C/C+, data structures, and operating system theory? If so, studying system programming is the answer now. Now it's time for practice!

Easily learn data structures and algorithms, which were difficult to learn with C++, in easy steps. Unlike typical lectures, this course combines data structures and algorithms, allowing you to learn them simultaneously while considering their interrelationships.

"I want to become a game developer!" For all beginners who aim to become game developers, Jushin Game Academy has prepared a C++ lecture for pure beginners! This is a lecture that explains the grammar in an easy way so that even complete beginners can understand it easily, rather than going into depth. Students who want to study in depth, please wait for the advanced C++ lecture that will be opened later!

The smartwatches, wireless earbuds, robot vacuum cleaners, cars, drones, kiosks, and medical devices we use every day contain small computers that receive user input, assess situations, and control the devices. These systems are called embedded systems. However, getting started with embedded systems is more difficult than it may seem. While it is easy to find examples of turning on an LED online, it is not easy to systematically learn the operating principles of real electronic devices, such as: "How does an electronic device respond when a button is pressed?" "How can it operate accurately at set intervals?" "How can multiple functions run simultaneously?" "How can it remember its settings even after being powered off and back on?" In this course, rather than memorizing complex theories or code, you will operate a small development board yourself and gradually understand the core principles of embedded systems one by one. Starting with basic hands-on exercises for controlling LEDs and buttons, you will progressively learn the core functions used to build real electronic devices, including Interrupts, Timers, PWM, ADC, Memory, and Watchdog. Finally, you will use an RTOS (Real-Time Operating System) to combine the functions you have learned individually into a single system in which multiple functions operate simultaneously. The goal of this course is not simply to teach you how to use a specific development board, but to build the foundational skills needed to understand and implement how hardware is controlled by software when working with various electronic devices and development boards in the future.

If you can master DB and programming, you should be more than halfway prepared for the information processing engineer exam. Let's take a look at the DB and programming parts, which are worth 45 to 55 points in the practical exam, and pass the written exam steadily.
