This is a networking course; the complete addendum to

We cover binary, Huffman encoding, networks from a mathematical perspective and many other network algorithms, such as those that appear in CLRS.

Students will benefit from this course by learning about networks. There is no greater benefit than this. (Which alone is many times the price of admission.)

This is a networking course; the complete addendum to

We cover binary, Huffman encoding, networks from a mathematical perspective and many other network algorithms, such as those that appear in CLRS.

Students will benefit from this course by learning about networks. There is no greater benefit than this. (Which alone is many times the price of admission.)

This course builds on foundations of networks such as Ford-Fulkerson, in which we learn the how, why and what of networks. We also address many burning questions on networks, such as "If networks were an animal... what type of animal would they be?" - well obviously an OCTOPUS. But why, you ask... I guess you'll just have to come and see.

Reviews summary

Deep dive into networking foundations and algorithms

According to learners, this course offers a comprehensive and deep dive into networking concepts, particularly excelling in its theoretical foundation and mathematical explanations of complex algorithms like Dijkstra and Ford-Fulkerson. Many students found the lectures to be incredibly clear and well-explained, praising the instructor's unique and engaging style that helps keep the material interesting. While highly beneficial for those preparing for Cisco certifications or seeking a strong foundation for a career in network engineering, some reviewers noted a strong emphasis on theory, suggesting it might be less hands-on than desired for pure practical application. Certain modules, such as logic gates and K-maps, were occasionally perceived as less relevant for day-to-day network administration by some.
Instructor's unique approach keeps learners engaged and simplifies complex topics.
"The instructor has a unique, engaging style."
"The instructor's humor kept me engaged."
"The instructor's passion for the subject shines through."
"The instructor explains difficult concepts in an engaging way, even with some quirks."
Excellent for those pursuing networking careers or certifications.
"I feel much more confident for my Cisco exam prep."
"This course is a must for anyone looking to build a career in network engineering."
"As a student preparing for certifications, the structured approach to OSI layers, TCP/IP, and error detection was invaluable."
Provides a strong foundation in networking theory and algorithms.
"Absolutely fantastic! This course provided a strong foundation in networking concepts. The lectures on the OSI 7 layers and network algorithms like Dijkstra were incredibly clear and well-explained."
"A solid course covering a wide range of networking fundamentals. It definitely helps bridge the gap between theoretical knowledge and real-world applications."
"I learned a lot about the OSI model and various network protocols... It provides a very strong theoretical understanding."
Deep dives into binary, logic gates, and K-maps were challenging for some.
"The binary and logic gates sections were a good refresher, but perhaps a bit too detailed for someone already familiar."
"The logic gates and K-maps were challenging and probably not essential for pure networking professionals unless they're going into hardware."
"I needed more practical configurations and fewer proofs. It's more of a computer science theory course with networking examples."
Course is strong on theory, but some desire more hands-on practice.
"The course has good information, but the delivery can be a bit eccentric. ...I wanted more hands-on labs."
"The course description promised practical applications for Cisco tests, but it's heavily theoretical."
"Mixed feelings. I needed more practical configurations and fewer proofs. It's more of a computer science theory course with networking examples."
