Rating: 4.0; Vote: 1
Today we start a three episode arc on the rise of a global telecommunications network that changed the world forever. We-re going to begin with computer networks, and how they grew from small groups of connected computers on LAN networks to eventually larger worldwide networks like the ARPANET and even the Internet we know today. We'll also discuss how many technologies like Ethernet, MAC addresses, IP Addresses, packet switching, network switches, and TCP/IP were implemented to new problems as our computers became ever-increasingly connected. Next week we-ll talk about the Internet, and the week after the World Wide Web! Pre-order our limited edition Crash Course: Computer Science Floppy Disk Coasters here!

I'm not sure if anyone will answer this but,
you said that they can chop up big transmissions into smaller pieces called packets. These packets take different routes to get to the destination resulting in them arriving in a different order. is this why google classroom uploads your files in a different order than how you put them in? If anyone sees this can you pls answer I'm very curious.

I was under impression that Switches do not relay data to all hosts on the network. The switch only broadcasts the data to all hosts when it does not have the necessary entry in its ARP table. In contrast, the hubs, a different type of a networking device, do relay data to all hosts at all times. Is this correct?

CCNA exam materials are a great resources for studying this topic because it's literally certification to prove your expertise in routing and switching. The OSI model is a great way to digest the topic and troubleshooting issues by taking the (cue music) levels of abstraction approach.

I'm taking the Google course over at Coursera and this has helped a lot in putting together all of the information I've learned. The Google courses are good, but information-dense without many visuals.

You are so interesting, i never see anyone who explains networking more than you you are a hero i wish you have all the semester. now i love networking thank you dear

Why switch passes a signal from one collision (Source) domain to another (Destination) the way that any computer from Source domain could see it? (6: 15 in video)

a bit of feedback: it is easier if the next 'episode' link is in the description
Apart from that, this video explained it really well, good job: )

As someone up here in Mpls, I got anxiety when she blew us up with a nuclear attack. 10: 30
Still loving every second of this course though.

I feel like some things were left out that could have been explained and the things that were explained were explained too fast.

I'm 31 and I've spent my entire life calling them -R-OW-ters-. I'm going to assume -rooters- is an English pronunciation thing?
