About this course: In this course, we trace the evolution of networks and identify the key concepts and functions that form the basis for layered architecture. We introduce examples of protocols and services that are familiar to the students, and we explain how these services are supported by networks. Further, we explain fundamental concepts in digital communication, and focus on error control techniques that include parity check, polynomial code, and Internet checksum. Students will be required to have some previous programming experience in C-programming (C++/Java), some fundamental knowledge of computer organization and IT architecture and a background in computer science is a plus.
Who is this class for: This course is primary aimed at undergraduate seniors and graduate students interested in communication networks and network administration, along with fresh out of college professionals with interest in communication/systems network.

Ratings and Reviews
I took undergraduate networking around 7 years ago and this course is very similar in some of the content. This is a first segment of what a normal semester would contain and it is easily completed in the 5 week timeline. The only downside is the lack of responses from anyone on the discussion forums.
The course is too rudimentary. Good a for someone who is completely new to networking.
The exercises and quizzes are good!
