Chapter 6 – Fundamentals of Computer, Networking and Cybersecurity (Without Explanation)
Applied Networking
Virtually all computers and mobile devices today are connected to some type of network and to the Internet. This means that configuring and troubleshooting computer networks is now a critical skill for IT professionals. This chapter focuses on applied networking with an in-depth discussion on the format and architecture of media access control (MAC) addresses and Internet protocol (IP) addresses, both IPv4 and IPv6, that are used to connect computers to a network. Examples of how to configure static and dynamic addressing on computers are included. Also covered in this chapter is the configuration of both wired and wireless networks, firewalls, and IoT devices.
You will learn how to configure network interface cards (NICs), connect devices to a wireless router, and configure a wireless router for network connectivity. You will learn how to configure wireless network basic wireless settings, Network Address Translation (NAT), firewall settings, and Quality of Service (QoS). You will also learn about firewalls, Internet of Things (IoT) devices, and network troubleshooting. At the end of the chapter, you will learn the six-step troubleshooting process and common problems and solutions for computer networks.
Your networking skills should include the ability to configure wireless networks so that hosts can communicate, configure firewalls to filter traffic, verify network connectivity, and solve network connectivity problems. There are three labs included in this chapter where you will build these skills. In these labs, you will configure basic settings on a wireless router and connect a PC to the wireless network, configure firewall settings to implement MAC address filtering, a DMZ, and single port forwarding, and finally, diagnose and solve network problems.
