Let's talk about how we connect devices to our networks and how we segment these networks. Well physically at least. This post isn't about WiFi.
Hubs
Let's start with the basics of how Network engineers explain how data traverses the network. When you click on the browser, or open a web page, or send an email on your PC, data is send over the network medium whether it be via copper, fiber, or wireless. At it's most basic form, all data is sent as little electrical pulses of 1's or 0's. But how does that web page go from words and pictures and CSS etc to those 1's and 0's? The answer of course is Data Encapsulation/Decapsulation.
So like many others (I'm hoping I wasn't the only one at least) I let my Cisco certifications expire during COVID. Partially because I wasn't ready to redo any of the CCNP exams, although I probably could have done the TSHOOT exam, and partially because I was lazy and COVID was here and it was too hard. That was back in 2019 and now I have no current Cisco certifications.
