Answer and explanation
Search

A personalized beginner's book, "created together," verified by 24 beta readers.

We actively reflected the difficulty, length, and learning elements that are just right for beginners, along with 24 beta readers.
Difficult terms and concepts are explained again, and appropriate examples and analogies are provided to make it easy for anyone to understand.
We also used various illustrations and characters so that even non-IT majors can learn in a fun way.
The greatest strength of this book is that the beginner's perspective and perspective of many beginners who have 'studied on their own' are reflected throughout the book.

Who is this book for?

● Anyone who wants to learn IT knowledge and the latest IT trends with specific goals such as 'understanding developers', 'communication with developers', and 'becoming a developer'
● Non-developer workers who have difficulty communicating with developers
● Beginners who are not majoring in IT and want to start developing by understanding IT knowledge and industry
● Non-IT professionals from other industries who want to transition to an IT-related industry
● Junior developers who struggle due to a lack of understanding of programming terms and concepts

Book Features

First, a solid learning design that systematically repeats the "7-step structure tailored for beginners"!

This book is structured to help you naturally memorize basic IT terms and concepts, as well as the latest AI technologies, through seven stages of repeated learning.
After warming up with the representative concepts of each section's topic through [Key Keywords] and [Before You Begin], you will begin to learn IT knowledge and coding terminology in earnest.
Finally, we conclude our study by reviewing what we have learned with [Key Points] and [Confirmation Questions].


2. 325 terms and concepts in your head through step-by-step learning in 〈easy〉, 〈medium〉, and 〈hard〉!

We provide difficulty tags for each title so that you can learn the 325 basic IT knowledge included in the text step by step.
Don't give up because it's difficult.
First, if you select and study the tags 〈easy〉 and 〈medium〉, which cover basic content, and then tackle the tag 〈hard〉, which covers more advanced content, you will be able to read content that seemed difficult easily.
With a variety of illustrations and everyday examples, 325 key terms and concepts will quickly become ingrained in your mind.

Third, video lectures and a study site to help you with your 'solo' studies!

For beginners who still find it difficult to learn from books alone, we provide videos of the author's lectures related to each topic, "Shallow Coding Dictionary."
You can learn more in-depth and diverse content not covered in the book directly through YouTube videos via QR codes within the text.
We provide a [YouTube Community] so that you can ask the author any questions you may have while learning.
We also run a [Solo Study Group] for those who want to study alone but are not yet confident in doing so.
With the Honkong Study Group, you can complete the course without giving up.

▶ Hongong Study Group: http://hongong.hanbit.co.kr

Fourth, we provide [Honkong Terminology Notes] that can be viewed easily anytime, anywhere!

We offer a [Hon-Gong Terminology Note] that compiles only the key concepts and terms you need to remember. The reason why people new to IT often struggle with programming is because of unfamiliar terminology.
When you can't remember a concept or term, try using the [Honkong Terminology Note] that you can refer to anytime, anywhere.
In addition to the terms presented, you can also enjoy the process of completing your own glossary by adding new terms.

Editor's Notes (Comments by the author)

Motivation arises from ‘shallow’ knowledge!

Do you truly want to take on the challenge of development, but feel like development is an insurmountable barrier because you have little knowledge of coding? This book strives to convey coding knowledge more easily than any other book for those people.
Before diving into the deep and wide ocean of development, try creating motivation for learning with 'shallow' knowledge!

Speaking is about vocabulary, and programming is about terminology!

Just as you might be afraid to speak in a foreign language if you don't know enough vocabulary, it's difficult to enter an industry if you don't know the industry's common terminology.
This book explains the terms and concepts used in the IT industry in an easy-to-understand manner, from the basics of communication to programming and the latest technologies.
We help anyone interested in programming overcome their fears and confidently take on the challenge of becoming a developer.

The foundation for becoming a 'true' developer is 'terminology and concepts'!

We've organized the core fundamental concepts and terms in software development into easy-to-understand sections, and then organized the content into stages (medium, hard) for deeper exploration.
From complete beginners to majors who haven't quite grasped the basics, we've explained the fundamentals using easy and interesting analogies so that anyone who aspires to become a developer can solidify their foundation.
Build a solid foundation in programming with this book!
