- - - - How the message is formatted or structured.
        
        Networking devices share information about pathways with other networks.
        
        How and when error and system messages are passed between
        devices.
        
        The setup and termination of data transfer sessions.
      - Protocol Interaction
        HTTP - an application protocol that governs the way a web server and a web client interact.
        TCP - transport protocol that manages the individual conversations.
        IP - encapsulates the TCP segments into packets, assigns addresses, & delivers to the destination host.
        Ethernet - allows communication over a data link & the physical transmission of data on the network media.
      - Protocol Suites and Industry Standards
        Set of protocols that work together to provide comprehensive network communication services.
        Development of TCP/IP
        Advanced Research Projects Agency Network (ARPANET) is the predecessor to today’s Internet of Defense for use by universities & research laboratories.
      - TCP/IP Protocol Suite
        
        TCP/IP Communication Process
        
        This frame is delivered to the nearest router along the path towards the web client. Each router adds new data link information before forwarding the packet.
        Sending data from a web server to a client the encapsulation procedure would be as follows:
        
        The webserver prepares the Hypertext Markup Language (HTML) page. The HTTP application layer protocol sends the data to the transport layer.
        
        The transport layer breaks the data into segments and identifies each.
        
        IP source and destination addresses are added creating an IP Packet.
        
        The Ethernet information is then added creating the Ethernet Frame, or data link frame.
        
        Receiving the data link frames from the web server, the client processes & removes each protocol header in the opposite order :
        
        First the Ethernet header is removed
        
        Then the IP header
        
        Then the Transport layer header
        
        Finally the HTTP information is processed & sent to the client’s web browser
