Everything Switches do - Part 1 - Networking Fundamentals - Lesson 4

Switching is the process of facilitating communication within a network. Switches are simply device's whose primary purpose is Switching.

This definition is intentionally worded as such because there are many devices that claim to do "switching" -- and all of those devices will follow the same rules and processes that Switches do to facilitate communication within a network.

In this video we discuss Switches as L2 devices, MAC address tables, and the three fundamental switch actions: Learning, Flooding, Forwarding. We then compare and contrast the act of sending data THROUGH a switch vs sending data TO a switch.
