What Youll Do: In your own words, describe what happens at every step of our network model, when a node on one network establishes a TCP connection with a node on another network. to continue establishing the TCP connection. One of Level 3s public DNS servers is__. Just like how binary is a way to represent numbers with only two the physical device that interconnects the computers, their . We will learn about the TCP/IP and OSI networking models and how the network layers work together. flags, so it knows it must respond with a SYN/ACK to computer 1, in order The big difference between the two is that TCP provides mechanisms to ensure that data is reliably delivered while UDP does not. Then it uses acknowledgements to make sure the connection is in proper state every time,a communication is made between the nodes(devices) which leads to extra traffic but necessary for important data transfers like phone calls. The TTL field is used for a cyclical redundancy check. (since both network A and network B are connected to the same router). This includes the specifications for the networking cables and the connectors that join devices together along with specifications describing how signals are sent over these connections.
