From data -> Segments (With Port address information) -> Packets ( which adds the destination IP address) -> Frames -> ( which again adds the Mac address) and then to bits. Best video tutorial for osi model in the KZitem. We need more top quality videos from you dan.

Thank you! I'm a total newb trying to compete the Google IT cert for a tech support job I applied for and the Network stuff is not well explained and it's beena struggle. I've needed so many additional resources and explanations to get through it and this has really helped me a lot to put it all together as far as the layers and their specific protocols, etc. I'm going to check out your other videos on the network layers. Thank you!!

If I open Chrome and log in to my KZitem account, and then I open a private browser via Chrome and log in to my friend's KZitem account, then does the Session layer distinguish between data that is sent to and from those two different types of Chrome browser windows?

You said that the application, presentation and session layer are data yet then proceed to say that layer 7 has a firewall that looks at packets. How are packets there if that layer only deals with data? Also, how is a switch layer 2 when the data has to travel through a router first?
@danscourses
4 жыл бұрын
The switch is layer 2 because it looks at the layer 2 information like source and destination mac addresses in the frame headers at layer 2. The switch maps source mac addresses to switch ports and forwards based on destination mac addresses.
@danscourses
4 жыл бұрын
In the Cisco Academy we use the word Packets to refer to the layer three PDU while other texts refer to the layer 3 PDU as Datagrams. I like Datagrams at layer 3 because people and software generally use the word "packets" to refer to the entire encapsulated network message unit. Like a "packet sniffing program" etc. At layers 5, 6, and 7 the PDU is data.
