EthernetNetwork Fundamentals – Chapter 9ObjectivesIdentify the basic characteristics of network media used in Ethernet.Describe the physical and data link features of Ethernet.Describe the function and characteristics of the media access control method used by Ethernet protocol.Explain the importance of Layer 2 addressing used for data transmission and determine how the different types of addressing impacts network operation and performance.Compare and contrast the application and benefits of using Ethernet switches in a LAN as apposed to using hubs.Explain the ARP process.Characteristics of Network Media used in EthernetIdentify several characteristics of Ethernet in its early yearsCharacteristics of Network Media used in EthernetDescribe the emergence of the LAN switch as a key innovation for managing collisions on Ethernet-based networksCharacteristics of Network Media used in EthernetIdentify the characteristics of state-of-the-art Ethernet and describe its utilization of cabling and point-to-point topography Physical and Data Link Features of EthernetStandards and Implementation Physical and Data Link Features of EthernetDescribe how the Ethernet operates across two layers of the OSI model Physical and Data Link Features of EthernetLogic Link Control – Connecting the Upper Layers Physical and Data Link Features of EthernetMedia Access Control (MAC)Physical and Data Link Features of EthernetPhysical Implementations of the Ethernet Function and Characteristics of the Media Access Control MethodMAC in EthernetFunction and Characteristics of the Media Access Control MethodCarrier Sense Multiple Access with Collision DetectionFunction and Characteristics of the Media Access Control MethodEthernet TimingLayer 2 Addressing and Its Impact on Network Operation and PerformanceThe Frame – Encapsulating the PacketLayer 2 Addressing and Its Impact on Network Operation and PerformanceThe Ethernet MAC AddressLayer 2 Addressing and Its Impact on Network Operation and PerformanceHexadecimal Numbering and AddressingLayer 2 Addressing and Its Impact on Network Operation and PerformanceAnother Layer of AddressingLayer 2 Addressing and Its Impact on Network Operation and PerformanceEthernet Unicast, Multicast and BroadcastCompare and Contrast the Use of Ethernet Switches versus Hubs in a LANLegacy Ethernet – Using HubsCompare and Contrast the Use of Ethernet Switches versus Hubs in a LANEthernet – Using SwitchesCompare and Contrast the Use of Ethernet Switches versus Hubs in a LANDescribe how a switch can eliminate collisions, backoffs and re- transmissions, the leading factors in reduced throughput on a hub-based Ethernet networkExplain the Address Resolution Protocol (ARP) ProcessMapping IP to MAC AddressesExplain the Address Resolution Protocol (ARP) ProcessARP – Destinations Outside the Local NetworkExplain the Address Resolution Protocol (ARP) ProcessARP – Removing Address MappingsExplain the Address Resolution Protocol (ARP) ProcessARP Broadcasts - IssuesSummary
