You use the Internet through your PC (Personal Computer), laptop, tablet, smartpad, and smartphone every day in everything you do. Through your own PC/laptop, you can easily learn everything about the Internet, and that is what this course is focused on. In this course ‘Introduction to TCP/IP,’ you will learn the operational functions of Internet technologies (which include IPv4, IPv6, TCP, UDP, addressing, routing, domain names, etc.) and your PC/laptop's security and gateway Internet setup and basic principles. In addition, through a simple Wireshark experiment, you will see the TCP/IP packets and security systems in action that are serving your PC/laptop, that serves you.

What's inside
Syllabus
My PC's Internet & Gateway
For the course 'Introduction to TCP/IP,' the first module is 'My PC's Internet & Gateway,' which introduced all important functions of the Internet that you use from your PC (Personal Computer), laptop, or smartphone. The first lecture 'My PC’s Internet Setup' explains the setup used in your PC/laptop. The next lecture 'Automatic Internet Setup using DHCP,' shows how your PC/laptop’s Internet connection is automatically setup if a local DHCP Server is supporting your network. Then the focus moves to the Default Gateway configuration in the 'IP Gateway/Router Configuration' lectures. As the Default Gateway is the gateway to the Internet for your PC/laptop, the lecture 'IP Routing Table' shows how the Default Gateway sends and receives all packets for your PC/laptop.

Reviews summary
Clear and practical tcp/ip fundamentals
According to learners, this course provides a solid and clear introduction to TCP/IP fundamentals. Many found the explanations of core concepts like IPv4, IPv6, TCP, and UDP to be easy to understand, even for those new to networking. The inclusion of a hands-on Wireshark project is frequently highlighted as a significant strength, offering a practical application of the theory. While some students noted that the course is truly introductory and doesn't delve into highly advanced topics, the consensus is that it establishes a strong foundation for further study or practical work.
Covers fundamentals, not advanced topics.
"The course is a true introduction. It gives you the what and the why, but not necessarily the deep dive into configuration or troubleshooting."
"For experienced network professionals, this course might feel a bit too basic, as it doesn't go into advanced routing or security topics in great detail."
"It lays a great foundation, but don't expect to become an expert after this; it's just the first step."
"While comprehensive for an intro, I would need other resources to understand more complex networking scenarios."
Introduction to key security topics.
"The security module was a useful overview, touching upon common attack types and defense mechanisms like firewalls and TLS."
"I found the section on Internet Security relevant and important for understanding the risks and protections involved in online communication."
"Learning about common attacks like DoS and Phishing provided good context, although it's just an introduction to security."
"It was good to see security protocols like WEP/WPA and SSH mentioned as part of the TCP/IP ecosystem."
Excellent starting point for networking.
"As someone completely new to networking, this course was exactly what I needed. It started from the basics and built up gradually."
"This is a perfect introductory course. It covers all the essential ground without being overwhelming."
"If you have zero prior knowledge of TCP/IP, this course is designed for you. It provides a great entry point."
"Foundations are explained well for someone just starting their journey in network understanding."
Practical hands-on packet analysis.
"The Wireshark project was the highlight for me. Seeing the packets in action really solidified my understanding."
"Doing the Wireshark labs allowed me to apply what I learned theoretically to real-world network traffic."
"The instructions for installing and using Wireshark were straightforward, making the hands-on part very accessible."
"Analyzing packets with Wireshark after learning the theory was incredibly valuable and practical."
Complex concepts explained simply.
"The instructor explains TCP/IP protocols in a very clear and easy-to-understand manner. Complex topics were broken down effectively."
"I appreciated how the course used simple examples, like the postal service analogy, to explain the 5-layer model."
"This course makes potentially dry material engaging. I felt I finally grasped how these foundational protocols work."
"I found the explanations about IPv4, IPv6, and addressing schemes particularly clear and helpful for my work."
