Course Introduction

Networking has enabled the mobile, cloud, and social networking, and introduced new paradigm to modern computing era. Advancement in networking technology is going to push the emergence of the Internet of Things, gigabit wireless networks, 5G Mobile technology further.

To become a player in the era of new network-enabled computing era, students must have a thorough understanding of networking concepts. In this lecture series, we will teach the basics of computer networks which are now considered as black box to let you build up on the technology and adopt to coming of new ideas.

The class will be organized into the following topics

Introduction to computer networks
Application layer
Transport layer
Network layer
Link layer
Wireless and Mobile Networks
Security
Multimedia Networking

Textbook
