In this chapter about networking I will be discussing the operations that network switches perform. Most of these concepts are discussed in Network+ or CCNA materials. I also provide some lab examples that you can use to get familiar with the hardware involved.
If you need lab items to test with, here is the cheapest switch I could find, and if you need a cheap windows PC, I have linked one, but if you want to test with more than one little computer, you might use a Raspberry Pi as your test unit.
5 port switch: amzn.to/4aqqaDt
HP PC: amzn.to/3V2vEQb
Terms I use in this video:
NIC - Network interface Card
MAC - Media Access Code (Your network serial number)
MAC Address Table - Your switch's memory of what serial number is learned on which of it's switchports.
Broadcast - A message sent to all switch ports
Unicast - A message sent directly to a specific port
Link Light - A green indicator light to show communication has been established.
Encapsulation - The technique of wrapping data up into transportation formats so that it can be sent between devices.
Ethernet Frame - The specific format a switch uses to encapsulate your data.
LAN - A local area network, or the network that your switches represent.
