This video covers the basics of the TCP/IP model, which is a four-layer architecture that is used in the vast majority of internet protocols. It is important to understand TCP/IP as it defines how packets are sent and received over the internet. The TCP/IP model is used in the first layer of the OSI model.

  • 00:00:00 The TCP/IP model is a four-layer architecture that is used in the vast majority of internet protocols. It is important to understand TCP/IP as it defines how packets are sent and received over the internet. This model is used in the first layer of the OSI model. The second layer is the transport layer, which is responsible for sending and receiving packets. The third layer is the application layer, which is responsible for sending and receiving data. The fourth and final layer is the network layer, which is responsible for routing packets.
  • 00:05:00 This video covers the basics of TCP/IP, which is a very reliable protocol. TCP is used for all of the information explained, while UDP does very little and really doesn't segment, order, or detect errors. It is, however, very fast. If we wanted to jump over the transport layer, we would spend a little bit of pp. Ultimately, we would have the application layer, which would be specific to users, such as email or messaging. This layer would correspond to the layer of the model or presentation, and the application layer protocols at the level of application. There are hundreds of protocols we could spend time on here, but for comparative purposes, TCP/IP is compared to its brothers, and how the level of application would equate to the layer of the presentation, transport would be the same as the internet, but with a different name, and access to the network would be called network, while actual physical connection would be called link. In reality, today we spend most of our time on TCP/IP, but we've done some nice additions like the level of internet being called "normal" and defining two levels of access to the network--data link and physical. This video ends with some conclusions about the model, TCP/IP, and
