OSI Model Layer 5, 6, and 7 -- Session, Presentation, & Application Layers -- what they actually do
Plenty of attention is given to L1-L4 of the OSI model... but very little attention is given to the Session Layer, the Presentation Layer, and the Application layer (Layers 5, Layer 6, and Layer 7). That's led to a lot of bad information existing about these three errors. So I decided to create a video that explained how these three layers work, and how they contribute towards the goal of Networking: sending data between two computers.
This video can be considered a follow up to my first two videos on the OSI model:
OSI Model - Layer 1, Layer 2, Layer 3

HTTP vs HTML: Unveiling Network Protocols using Telnet
Просмотров 30 тыс.8 месяцев назад
At the surface, this video is about HTTP, HTML, and Telnet. But beneath that this video is actually a demonstration of how every Network Protocol works. A Connection is made via TCP or UDP, a request is sent, a response is received. We demonstration this with HTTP / HTML / Telnet, but this same sequence occurs with nearly all other protocols as well. In this demonstration, we show you exactly w...
TLS 1.3 Handshake - many CHANGES from prior versions!
Просмотров 15 тыс.Год назад
The TLS 1.3 Handshake changes significantly from the TLS 1.2 (and prior) handshake. In this video we discuss 4 major changes to the TLS handshake with the latest version: - TLS 1.3 Handshake is shorter, only one round trip (1RTT) - TLS 1.3 Handshake is mostly encrypted (everything except the Client Hello and the Server Hello) - TLS 1.3 Handshake encrypts the Client Certificate (as well as the S...
TLS 1.3 Cipher Suites - Here is what CHANGES!
Просмотров 11 тыс.Год назад
A Cipher suite is a selection of one specific protocol for four security services: Key Exchange, Authentication, Symmetric Encryption, and Hashing. In TLS 1.2 and prior, a single Cipher Suite selected a protocol for all four of these... in TLS 1.3, a Cipher Suite changes to only specify a protocol for two of these: Symmetric Encryption and Hashing. Here is what a Cipher Suite looks like in TLS ...

    Hello All - I will keep my comments short - this video series on subnetting is the most simple and gratifying that I have seen. All the others just confused me but @PracticalNetworking cleared the clutter and allowed me to master subnetting.

    Hands down the best subnetting series I have found. I am currently taking the CCNA course through Cisco and I have watched TONS of videos on subnetting over the last two months, and you nailed it my friend. I get it now. I am going to get your networking course as a companion to explain the information I don't understand in my class (which is plenty🙂). Thank you so much!

    Thank you SO MUCH for this series!!! I have been struggling with this topic, and there are so many variations to the cheat sheets, but none of them were helping me. This series is the first time it truly clicked! I also greatly appreciate how you made it a point to say that the different ranges use different octets. Before now, it made no sense why the numbers were always placed in different octets.

I've wanted to learn some networking for a long time and now I actually have to and I'm really happy that I found this. Feels really well thought through. Thank you!

    Hello, I came to these video series by chance and these are the best I have seen. I have a question about the cheat sheet though. It only goes as far as /128 for the Group Size. How do you solve for all 7 attributes when the target IP is 137.98.249.121/18?
