Introduction to Switching, WiFi Topology, and Network Address Translation (NAT)
Yunusa Mohammed Jeddah
In this module, we’ll cover switches and how they receive information. The module will introduce the concept of network address translation (NAT) and its different types, with a focus on wireless networks in a LAN setting using Wi-Fi networks. The module will also explore the concepts of the client-server model and the definition of workgroups and domains, as well as their practical application for devices that join networks.
