關於此課程：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.
此課程適用人群：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.
This course contains content similar to the first few weeks of an undergraduate networking course (I had one ~7 years ago). The timelines are very relaxed and is easily completed in the 5 weeks. However, the content is DIFFICULT without a background in knowing how to study -- watch the lectures, read the slides, read the book, work through problems, and expand your mind. The lectures are top-notch and realize those alone, in any course EVER, are not enough to learn difficult content. The only downside is the lack of responses from anyone (including mods) on the discussion forums.
