TCP/IP Stack
Текст Раскадровки
- The TCP/IP Stack uses 4 different layers
- This storyboard is going to be a detailed look at the TCP/IP Stack
- The 4 layers are: Application, Transport, Network, and Link
- if it is a web browser then the protocol would be HTTP, HTTPS, FTP etc
- The application layer uses an appropriate protocol relating to whatever application is being used to transmit the data
- The first layer is the application
- After the connection has been made, it splits the data to be transmitted into packets
- Transport is responsible for establishing an "end-to-end" connection
- The second layer is Transport
- This layer adds the source IP address and the destination IP address to each packet
- Socket = IP address + Port
- All routers operate at this layer. They use the IP address to know the destination the packets are heading to.
- The third layer is Network
- The MAC address is changed at each hop on the router
- It is responsible for adding The MAC address of both the Source device and the destination device.
- The fourth and final layer is Link
- This layer represents the physical connection between various network nodes
- Well this is the end of our journey through each layer of the TCP/IP Stack
- We hope to see you again someday on some other topic
