Excellent course content, good analogies and examples. Explained in an easily understood manner. Content was perfect for an introductory course.
Excellent course. Lots of information was provided, however it was a very easy-to-follow format and it was kept interesting.
Excellent use of illustrations as a means of clarifying initially difficult concepts. Very clear writing style. I also enjoyed the humor. Overall, an excellent course.
Finally, someone who completely understands his subject and is capable of conveying that understanding to others. This course met the criteria for effective teaching: Explain clearly, Illustrate and show practical application. I will be back for more!!!
I especially liked the instructor's writing style and analogies. I feel the course taught me what it promised.
I really, really enjoyed this class and I am a recent Information Systems graduate. There needs to be more instructors like David Iseminger. He is very user friendly. I will take his next course.
I think course was very informative organized very well and the concepts built on each other to help with understanding the topics. I really enjoyed the course and plan to take additional courses in the future.
I thought the presentation of the material by the instructer was done in a way that made it easy to understand the various complex issues in this course.
I wanted to learn more about a complex and somewhat abstract subject ie networks and networking. I was pleased that the writing style kept my interest and introduced complex subjects in a matter of fact style. I don't think I would have gotten as much out of just reading a book on the subject. Certainly has proven helpful to me in my day to day dealings with computer networks and the internet thank you.
Course Code: itn
In the first lesson you’ll learn how networks have evolved over the last hundred years and by the end of this lesson you’ll have a framework of knowledge that will take you through the rest of the course. Then you will jump right in to networks and networking, and learn how they work.
Learn how to tell the difference between client/server and peer-to-peer networks, and when to use one instead of the other. Then you’ll learn all about the Ethernet. In addition, you will find out the difference between a star topology and a bus topology and the advantages of each.
You will explore how routers operate. You will find out how the Internet can create a global network by interconnection network segment and routing data. Then learn how computers communicate by using something called protocol, which is similar to language.
You will learn how networking protocol TCP/IP operates. Then you will learn how the Domain Name System (DNS) uses addresses to direct data to its rightful owner-similar to how we use street addresses.
You will look at Wide Area Networks (WANs) and how they compare to Local Area Networks (LANs), and discuss different types of modern WANs. You’ll learn about how data get sent over long distances, and how the Internet changed long-distance network connections. Then you will explore means of connection to remote LANs, and how DSL and cable Internet access works. You will also learn about other ways people connect to the Internet, including wireless and cellular networks.
This lesson will allow you to apply many of the concepts you’ve learned so far in this course. You will walk through the process of building a network. You will connect to the Internet using broadband connections, configure a home router, and test what you’ve done. Finally, you will learn how new information about networks and networking can be quickly understood.
