Computer networking is one of the most exciting and important technological fields of our time. The Internet and its applications and services, such as Web, email, Voice over IP, video-on-demand, mobile networks, etc., are changing the ways we live and work. The networking/Internet field and all that it entails are a vast new frontier, full of amazing challenges. There is always room for innovation. This course covers fundamental computer networking concepts and principles with exercises which guide students to apply the networking theory and design principles, verify their understandings, and build a solid foundation for creating innovations in today’s Internet. The course serves students in two ways. For those students who will continue in computer networking, it lays foundations of protocol design principles, secure network architecture and design skills, and experience with TCP/IP network management protocols, which are necessary to take more advanced courses in graduate study and/or technical training in the industry. For those not continuing in computer networking, it covers basic networking knowledge, network configuration, application-level network communications methods, and in-depth understanding of the inner-workings of computer networks and their development.
