I only care about that Transport layer, man. Gotta have that UDP for the games—low latency is king 👑. Drop a packet or two? No problem, as long as my shots land with no lag!

OSI model? More like LOL model. My cat knows more about networking than this and she thinks TCP is a brand of cat food.

Don't even get me started on the security implications of neglecting OSI knowledge. Half the time, breaches occur because someone messed up at the presentation layer, like with a flawed encryption. Educate people on OSI, and maybe I'll lose my job haha.

Cables, pssh... it's all about wireless now. Wi-Fi, LTE, 5G... Who needs cables when you got all that?

Fantastic wrap-up! I think many forget that the OSI model isn't just academic; it's super useful for troubleshooting. Understanding what each layer does means you can pinpoint where things are going wrong in a network. Say you've got an application that isn't connecting correctly, walking through the OSI layers one by one helps you figure out if it's a physical issue (like a disconnected ethernet cord), a transport issue (maybe TCP isn't properly handshaking), or maybe an application layer issue with DNS resolution. Plus, I love explaining to newbies how Wi-Fi fits into this, always cool to see the realization that it's really just part of that first layer!

Is this model still relevant with everything moving to the cloud? Feels like it's more for the history books at this point.

Trying to cram for a test on this stuff and your breakdown strangely makes more sense than my textbook 😂. I get the 'Wild West' comment, cause theory is one thing, but putting it into practice never goes as smoothly.

Your summary is spot on, really drives home how integral the OSI model is to literally everything online. Just to add, people often forget about the importance of the physical layer because it's so... well, physical in a digital world. But without the right setup there, layers 2-7 might as well not exist! Seen too many times a bad cable or misconfigured hub wreak all kinds of havoc.
