Chapter 3: Network Protocols and Communications

1. Rule Establishment

   • An identified sender and receiver
   • Common language and grammar
   • Speed and timing of delivery
   • Confirmation or acknowledgment requirements

2. Message Encoding

   • Encoding is the process of converting information into another acceptable form, for transmission

3. Message Formatting and Encapsulation

   • An identifier of the recipient
   • A salutation or greeting
   • The message content
   • A closing phrase
   • An identifier of the sender

4. Message Size

   • people communicate with each other, the messages that they send are usually broken into smaller parts or sentences

5. Message Timing

   • Access Method
   • Flow Control
   • Response Timeout

6. Message Delivery Options

   • Unicast
   • Multicast
   • Broadcast

7. Rules that Govern Communications

   • A protocol suite is A group of inter-related protocols necessary to perform a communication function.

8. Network Protocols

   • Hypertext Transfer Protocol (HTTP)
   • Transmission Control Protocol (TCP)
   • Internet Protocol (IP)

9. Development of TCP/IP

10. TCP/IP Protocol Suite

    • OSPF
    • EIGRP
    • DNS

11. TCP/IP Communication Process

12. Open Standards

    • IEEE
    • IETF
    • ITU
    • ICANN

13. Internet Standards

    • Internet Society (ISOC)
    • Internet Architecture Board (IAB)
    • Internet Engineering Task Force (IETF)

14. Electronics and Communications Standard Organizations

    • Electronic Industries Alliance (EIA)
    • nstitute of Electrical and Electronics Engineers
    • Telecommunications Industry Association (TIA)

15. The OSI Reference Model

    • The OSI model provides an extensive list of functions and services that can occur at each layer.

16. OSI Model and TCP/IP Model Comparison

17. Message Segmentation

    • Segmentation
    • Multiplexing

18. Protocol Data Units

    • Data
    • Segment
    • Packet
    • Frame
    • Bits

19. De-encapsulation

    • is the process used by a receiving device to remove one or more of the protocol headers.

20. Network Addresses

    • Network layer source and destination addresses
    • Data link layer source and destination addresses
    • Source IP address
    • Destination IP address

21. Data Link Addresses

    • deliver the data link frame from one network interface to another network interface on the same network.

22. Role of the Network Layer Addresses

    • Network portion
    • Host portion
