Title: Module 6 Introduction
Course: CNT 2001 Computer Networks & Communications > Section: Module 6 Networking Devices

Introduction

Until now (with the exception of media) we have largely been exploring networks on a logical level. Now, it’s time to get physical. We will explore the major physical devices that make networks possible, and we will see how they all fit together. We will explore network devices that are commonly found on local area networks, such as network interface cards, hubs and switches, and routers. We will also explore wireless networking devices and virtual networking concepts.

Learning Objectives:

- Compare various network connectivity devices such as NICs, modems, and wireless NICs.
- Explain what a media converter is and how it is used in modern networks.
- Explain what repeaters and hubs are and the role they play in networking.
- Explain what bridges and switches are and how they are related.
- Explain what VLANs are and how they are configured and how they are used in networking.
- Explain what CSU/DSUs are and the role they play in networking.
- Discuss basic information about routers and how they are used in a network.
- Explain what firewalls are and some of their basic function in networking.
- List several different types of servers that are commonly used in modern networks.
- Discuss common wireless network devices that are in use today and how they are used in conjunction with wired network devices.
