TCP/IP Model (Internet Protocol Suite) | Network Fundamentals Part 6

TCP/IP Model (Internet Protocol Suite) | Network Fundamentals Part 6
You’ve seen the OSI model, now see the TCP/IP model! It started as a competitor, but has grown into a suite of commonly used protocols.

It has gained popularity over OSI in a practical sense, as it was quick to standardise. The OSI model was slower, and missed out.

We’re going to look at the four (or is it five?) layers of the TCP/IP model, and see how they contrast to OSI.

In the next video, we’re looking at the TCP and UDP protocols, what they’re for, and how they’re different.

Overview of this video:

0:00 Introduction

4:31 Application layer

5:32 Transport layer

6:51 Network layer

8:08 Data Link layer

9:33 Physical layer

LET'S CONNECT

I'm going to share your playlist with my classmates. Everything I've heard so far is very helpful and fills in a lot of blanks from the lack of instruction in my class. You're doing us all a great service, thank you!

Quiz #2 Questions/Answers:
1. TCP/segment (Transport layer 4) deals with logical port numbers
2. IP/packet (Network layer 3) deals with source and destination IP addresses
3. Ethernet/frame (DataLink layer 2) deals with MAC address on a local network and does CRC to check the integrity of the frame. I think it uses hash algorithm such as MD5 or SHA1.

God, I wish I had been smart enough to use these 3rd party videos to help with understanding basic networking for my cybersecurity class in spring. The things we were meant to study from were 10-15 year old videos by a professor at uni and an unnecessarily lengthy and boring textbook. Thanks for helping out! I'm gonna use these to finally complete this course and graduate!

[YexyYT]

Recent graduate here! B.A. In cyber security. Been using these videos to refresh some of my network knowledge. (End of the year was crowded with other classes). I applied to be the Sys Admin of my college. I had a meeting with the supervisors prior to graduation and they sounded optimistic about the possibility of employment. I'm currently working a summer job as IT Desktop in the mean time. These are very informative along side the projects I've been doing. Fingers crossed I get the job and thank you for the excellent resources!

[yangliu]

You are talent teacher！！Make the complicated thing simple.

[francelucylucy]

I always think that ... professor from university might not always explain things well. But very rare to meet someone like you to explain thing very clear. Thank you, I really appreciate a lot your lectures.

[victorgarcia]

This guy is calm and explains very well the concepts

[brianmisasa]

I especially like how you explain adding headers as the data moves through each layer

[danimoosakhan]

Quiz #5:
Data link (Ethernet protocol)
Network (IP protocol)
Transport (TCP and UDP)

[musicmher]

All of your videos are incredible.
I am watching them with great pleasure .
Thank you 🙏

[vtrandal]

Regarding the Transport layer, you said "Put simply, they (TCP/IP and UDP) use port numbers to track sessions." Thank you for that perspective. The name "port" bothered me for years and now its purpose is all that matters. Thank you.

[Marius-vwhp]

This guy sounds excactly like the guy on my Headspace app.

[trycryptos]

Watched on 20/2/22. Great information.

[uweguevara]

Quiz 3: 1. Should be: 4. Http, TCP, IP and Ethernet and 1 Ehternet trailer. 2° 2nd Model has just 1 upper layer instead of 3. 3° Ethernet, IP and TCP.

[geogmz]

Haven't watched the video yet.. But for sure! Well explained your channel deserves more visibility.

Thank you so much for doing this. You probably saved me a lot of sleepless nights. Exceptional content! Keep up the good work.

[OchirBFolo]

The world's best explanation, keep it up 🎊thank you +Network Direction

[rendogrendog]

Great Video man! Keep up the good work. I like videos where basics are explained.

[angusquigley]

Great Video - It made a lot of sense, better than anything I have read so far!
