Today, Internet access is considered a basic human right.
Nearly every computer, mobile device, and even wearable that we interact with on a daily basis are connected over the network. We cannot imagine a computer without a network; we cannot imagine our life without a networked computer.

In this light, this course is designed to help the students learn from mainly three dimensions as follows:

1. Lectures.
- We will discuss basic principles and topics of fundamental concepts concerning the technology and architecture of the Internet. Topics to be covered mainly in this course will include IP, TCP/UDP, and Internet applications.
- The lectures will also feature advanced topics, namely "network beyond connectivity", where we will taste modern case studies that utilize the network as a physical sensor, a privacy defender, a social facilitator, and so on.

2. Brand-new Assignments.
- As of 2022, this course will feature whole re-designed assignments. These assignments will guide the students to develop hands-on technical experiences by building the key mechanisms of the protocols making modern computers talk to each other.

3. Global Industry.
- A specially invited POSTECH graduate (now working for a tech giant in Silicon Valley) will offer a guest lecture on the cutting-edge global networking industry.
- This guest lecture is to broaden the eyes of our fellow POSTECH juniors, to depict a career path that may be yours one day, and to give a crisp purpose for learning networks.
