TAILIEUCHUNG - Lecture Network Fundamentals – Chapter 2: Communicating over the Network

In this chapter, you learned to: 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;. Inviting you to refer. | Communicating over the Network Network Fundamentals – Chapter 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. 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 Network Structure Describe how messages are communicated Data is sent across a network in small “chunks” called segments Network Structure Define the components of a network Network components Hardware Software Network Structure End
