What is the TCP/IP model? It's a model to standardise computer networking.

The OSI model, while widely referenced isn't used in the real world. The TCP/IP model, however, is the real deal. Thankfully, it's not all that different.

Here is the original TCP/IP model.
Application, Transport, Internet, and Link.

Just like the OSI model, it's numbered from the bottom up but the direction depends if you're sending or receiving traffic.

So this is the original TCP/IP model, but, it has been updated.
The link-layer has been split into Data Link and Physical
and the Internet Layer has been renamed the Network layer.

Layer 5: Application protocols such as HTTP, FTP, and SMTP

Layer 4: The two most common transport protocols are TCP and UDP.
Port numbers are also added here.

Layer 3: At the Network layer, we have the Internet Protocol or IP.
Routers also commonly operate at this layer

Layer 2: The data link layer contains Ethernet related protocols.
Switches usually operate at this layer. Although you can get layer 3 switches that have routing capabilities

Layer 1: Think of everything you can touch and feel here.
Things like cables, hubs and Network interface cards.

Jamal : I learnt more here than reading a full long page of info, thanks dude
Itay Barok : I learned some new features of the tcp/ip model so thank you:
- There was a 4 layer tcp/ip protocol where the phisical layer and data link layer was a link layer and the name of networking layer was ethernet layer.
- The idea of 2 sides encapsulation in the link data layer is that the head part contains important staff like mac addresses and the tail contains some error checking data.
- Great diagrams to easy learning
- Super useful information

Keep going
Bace : Wonderfully done! The diagram helped explain how and what happens at each layer. Previously I didn’t understand but you guys made it clear as day! Definitely tuning in for more
unistern : this video made me learn something i spend 3 years at university and never really understood all the bullshit our professors was explaining. Thank you guys. keep it up
Mia Hardianti : Best explaination ever ! Effective and simple !!! You helping me so much thank you ❤️
