What the Book Is About
“쉽게 배우는 데이터 통신과 컴퓨터 네트워크” is a textbook designed to introduce the fundamentals of data communication and computer networking in an easy-to-understand manner. The 3rd edition typically expands on earlier versions with updated networking technologies and clearer explanations.
It is often used in university-level introductory courses.
Core Topics Covered in the Book
This textbook generally covers foundational networking concepts such as:
Basics of data communication systems
Network models like OSI and TCP/IP
Transmission media (wired and wireless)
Data encoding and signal transmission
Network protocols and architecture
Internet structure and routing
Each topic is explained in a simplified way to help beginners understand complex systems.
Understanding Data Communication
Data communication refers to the process of exchanging data between two or more devices through a transmission medium. This can include:
Computers communicating over the internet
Mobile devices sending data through wireless networks
Servers exchanging information across data centers
Understanding this process is essential for modern computing systems.
Computer Network Fundamentals
A computer network is a system that connects multiple devices so they can share resources and information. Networks can be classified into:
LAN (Local Area Network)
WAN (Wide Area Network)
MAN (Metropolitan Area Network)
The textbook helps learners understand how these networks are structured and how data flows between them.
Importance of OSI and TCP/IP Models
Two key models discussed in networking education are:
OSI Model (7 layers): A conceptual framework for understanding network communication
TCP/IP Model: The practical model used in real-world internet communication
These models help students understand how data moves from one device to another across multiple layers of processing.
Why Students Search for PDF Versions
Many students search for PDF versions of textbooks because:
Digital access is more convenient than physical books
It allows study on mobile devices or laptops
It is easier to search within text
It can be used for quick revision before exams
However, not all PDF versions available online are authorized or legal.
