ITN 101 - Introduction to Network Concepts - 3 Credits
Professor:  Charles Kellermann


In this course, you will learn about network topologies, protocols, network components, cabling, network operating systems, directories, security, printing, data backup, installation of file servers, workstations, and applications.

What you learn in this course will benefit you by providing a comprehensive and up-to-date survey of basic networking concepts and terminology. This will enable you to build a solid foundation for subsequent courses in the NVCC Information Technology (IT) Network Administration and Network Engineering programs of studies. For students majoring in other IT programs it will help you to understand how networks support applications and are supported by hardware and software. The course provides a thorough coverage of designs - topologies, media, architectures, and protocols - that compose modern IT networks. If you will be using the principles covered in this course for your everyday job, then it will also help to prepare you for the various professional certification tests that are available in the IT world (such as the Network+) - do note that you will need more study, especially of sample exams, before you invest $100+ for these exams.

There are four (4) exams in this course. You are expected to take your examinations at one of the NVCC campus Testing Centers. Be sure to allow enough time to complete your exam before the Testing Center closes; Testing Centers have specific policies relating to the administration of ELI exams. You will need to take a photo ID, your NovaConnect empl ID number, and the appropriate Exam Pass when you go to the Testing Center.
