Informações sobre o curso: 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.

Para quem é direcionado este curso: 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.

nice to enroll with this course

Studying the advancement of any area of technology will not only inspire your natural interest, it will also give you a deeper understanding of the main achievements in that are. It will make you aware of the existing trends, and help you to evaluate the prospects of specific developments.

This course all above said.

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.
