What you will gain after the course

  • Essential Computer Science (CS) Knowledge for Developers

  • Essential Computer Science Knowledge for Developers Connected to Technical Interviews

In the age of AI coding,

Nevertheless, there are immutable truths of developers that never change!

Essential Computer Science (CS) Knowledge for Employment

  • Direct instruction from a computer science bestselling author allows you to quickly learn only the essentials.

  • You can learn 5 essential computer science subjects for developers easily and quickly.


  • Beyond simple code writing, you can learn the fundamental operating principles of computers.

[This is Computer Science for Employment - Hanbit Media] Author's Direct Lecture


Have you ever had thoughts like this?

  • Faster than developers at coding

  • I want to learn by discussing with people in similar fields.

  • I want to take a course where the instructor provides thorough feedback!



Even in the age of AI development, the core that cannot be replaced: computer science major knowledge!

You can systematically understand the fundamental principles that remain unchanged even when trends shift.

You can systematically build problem-solving skills and thinking structures that determine development difficulty.

You can quickly master only the essential CS fundamentals required for both technical interviews and practical work.



I'll draw a computer science map for you.

At the end of your learning journey, you'll be able to draw your own concept map of computer science.


CS knowledge is not a subject for memorizing keywords.

Memorizing keywords alone cannot prepare you for in-depth technical interview questions or help you incorporate CS knowledge into code.


This course references all possible major textbooks currently used in universities

After carefully selecting content that is essential for developers

This is a 'principle-based understanding' course that has been compiled and reviewed by professors and senior developers.


Computer Science Major Roadmap

A course already taken by over 26,000 students,

Direct instruction from a bestselling author specializing in Computer Science (CS)!

  • You can attend direct lectures by an author who has written computer science books that have been IT steady sellers/bestsellers for over 95 weeks.

  • You can quickly learn only the essential parts of textbooks used in universities.

  • Even in the age of AI tools, you can develop 'essential CS capabilities' that cannot be replaced,

1⃣ Providing the Big Picture of Computer Science

We provide a computer science learning roadmap for every lecture.

Grasp extensive specialized knowledge at a glance.

2⃣Computer Science for Practical Work

Not just a list of simple theoretical knowledge,

We explain with a focus on practical application in real-world development.

3⃣Understanding-Based Classes

Not just simple keyword listing/memorization classes,

I want to develop computational thinking skills.

4⃣Lectures for Everyone

Easy explanations that even non-majors can understand,

I structured it so that knowledge is organized for those with a major in the field

You'll learn this kind of content

  • Learn the 5 core computer science subjects taught in universities.

  • Learn focusing on the core concepts and principles that appear most frequently in technical interviews.

  • Develops fundamental CS thinking skills needed to understand how code works in real-world practice.


Computer Architecture

Operating Principles of Computer Hardware

  • Learn the principles of how hardware executes programs and
    the fundamentals of performance.



Operating System

The core program that breathes life into hardware

  • Understand what operating systems like Windows and macOS are, and what tasks they perform for the programs we create and run.


Data Structures

Efficient Data Management

  • Even with the same data, how you manage it can greatly affect
    performance and capacity.

  • Learn methodologies for efficient data management.


Network

Principles of Communication Between Computers

  • Understand the principles of how communication between computers works.

  • Learn the essential background knowledge needed to build robust programs that can withstand high-traffic situations.


Database

Efficient Storage and Management of Large-Scale Data

  • Learn how to safely store vast amounts of data and
    efficiently query it.

  • Understand databases through hands-on practice.

Special Challenge

I recommend this for people like this

Those who want to build 'fundamental CS skills' to stay ahead in the AI era

Those who want to systematically organize CS fundamentals from the basics

Those who want to quickly grasp the 'big picture of their major subjects' in a short period of time

Those who want to understand the principles of how code works in practice

Expected Questions Q&A 💬

Q. Since it's a free course, wouldn't the quality be low?

This course absolutely does not fall behind in quality compared to any paid course.

Despite being essential background knowledge that all developers (and aspiring developers) should know,
it was created for free to help developers (and aspiring developers) who might feel burdened by excessive course fees.

Q. Do I absolutely need to have the book?

This is optional. However, this class is conducted based on the book,
and no separate learning materials are provided.
Therefore, if you want learning materials/review materials, we recommend purchasing the book from the link below.
