The document discusses key concepts in network fundamentals including: - The structure of networks including devices, media, protocols, and layered models like TCP/IP and OSI. - How messages are communicated across networks in segments using hardware, software, end devices, and intermediary devices. - The roles of protocols in allowing different devices to communicate successfully in a standardized way. - How layered models and encapsulation allow messages to be broken into packets and routed between sources and destinations.
Exploration network chapter2
- 1. Communicating over the Network Network Fundamentals – Chapter 2
- 2. Objectives Describe the structure of a network, including the devices and media that are necessary for successful communications. Explain the function of protocols in network communications. Explain the advantages of using a layered model to describe network functionality. Describe the role of each layer in two recognized network models: The TCP/IP model and the OSI model. Describe the importance of addressing and naming schemes in network communications.
- 3. Network Structure Define the elements of communication 3 common elements of communication message source the channel message destination Define a network data or information networks capable of carrying many different types of communications
- 4. Network Structure Describe how messages are communicated Data is sent across a network in small “chunks” called segments
- 5. Network Structure Define the components of a network Network components hardware software
- 6. Network Structure End Devices and their Role in the Network End devices form interface with human network & communications network Role of end devices: client server both client and server
- 7. Network Structure Identify the role of an intermediary device in a data network and be able to contrast that role with the role of an end device Role of an intermediary device provides connectivity and ensures data flows across network
- 8. Network Structure Define network media and criteria for making a network media choice Network media this is the channel over which a message travels
- 9. Network Types Define Local Area Networks (LANs) - A network serving a home, building or campus is considered a Local Area Network (LAN)
- 10. Network Types Define Wide Area Networks (WANs) - LANs separated by geographic distance are connected by a network known as a Wide Area Network (WAN)
- 11. Network Types Define the Internet The internet is defined as a global mesh of interconnected networks
- 12. Network Types Describe network representations
- 13. Function of Protocol in Network Communication The importance of protocols and how they are used to facilitate communication over data networks A protocol is a set of predetermined rules
- 14. Function of Protocol in Network Communication Explain network protocols Network protocols are used to allow devices to communicate successfully
- 15. Function of Protocol in Network Communication Describe Protocol suites and industry standards A standard is a process or protocol that has been endorsed by the networking industry and ratified by a standards organization
- 16. Function of Protocol in Network Communication Define different protocols and how they interact
- 17. Function of Protocol in Network Communication Technology independent Protocols -Many diverse types of devices can communicate using the same sets of protocols. This is because protocols specify network functionality, not the underlying technology to support this functionality.
- 18. Layers with TCP/IP and OSI Model Explain the benefits of using a layered model Benefits include assists in protocol design fosters competition changes in one layer do not affect other layers provides a common language
- 19. Layers with TCP/IP and OSI Model Describe TCP/IP Mode
- 20. Layers with TCP/IP and OSI Model Describe the Communication Process
- 21. Layers with TCP/IP and OSI Model Explain protocol data units (PDU) and encapsulation
- 22. Layers with TCP/IP and OSI Model Describe the process of sending and receiving messages
- 23. Layers with TCP/IP and OSI Model Explain protocol and reference models A protocol model provides a model that closely matches the structure of a particular protocol suite. A reference model provides a common reference for maintaining consistency within all types of network protocols and services.
- 24. Layers with TCP/IP and OSI Model Define OSI
- 25. Layers with TCP/IP and OSI Model Compare OSI and TCP/IP model
- 26. Addressing and Naming Schemes Explain how labels in encapsulation headers are used to manage communication in data networks
- 27. Addressing and Naming Schemes Describe examples of Ethernet MAC Addresses, IP Addresses, and TCP/UDP Port numbers
- 28. Addressing and Naming Schemes Explain how labels in encapsulation headers are used to manage communication in data networks
- 29. Addressing and Naming Schemes Describe how information in the encapsulation header is used to identify the source and destination processes for data communication
- 30. Summary
