The aim of this module is to:Give learners practical skills with Ethernet technologies.Give learners a theoretical understanding of the technologies used in building a small LAN.Provide learners with an understanding and ability to apply theories for design and troubleshooting issues in a small LAN.
Communicating over the Network
Describe the role of each layer in two recognized network models: The TCP/IP model and the OSI model. Explain the advantages of using a layered model to describe network functionality. Explain the function of protocols in network communications. Describe the structure of a network, including the devices and media that are necessary for successful communications.
Application Layer Functionality and Protocols
Define the application layer as the source and destination of data for communication across networks Explain the role of protocols in supporting communication between server and client processes. Describe the features, operation, and use of well-known TCP/IP application layer services (HTTP, DNS, SMTP).
OSI Transport Layer
Explain the role of Transport Layer protocols and services in supporting communications across data networks Analyze the application and operation of TCP mechanisms that support reliability Analyze the application and operation of TCP mechanisms that support reassembly and manage data loss.□ Analyze the operation of UDP to support communicate between two processes on end devices
OSI Network Layer
Identify the role of the Network Layer, as it describes communication from one end device to another end device Examine the most common Network Layer protocol, Internet Protocol (IP), and its features for providing connectionless and best-effort service□ Understand the hierarchical addressing of devices and how this allows communication between networks□ Understand the fundamentals of routes, next hop addresses and packet forwarding to a destination network
Addressing the Network: IPv4 abd IPv6
Binary and Decimal conversion IPv4 and IPv6 address classification, Address assignment Calculate addressing components□ Use common testing utilities to verify and test network connectivity
OSI Data Link Layer
Data Link layer protocols Data Link transmission Media access control□ logical and physical network topologies □ encapsulating packets into frames□ The Layer 2 frame structure
OSI Physical Layer
Physical Layer protocols Physical Layer signalling and encoding Identify common media - copper, wireless and fibre
CSMA/CD and CSMA/CA Functions of Ethernet Layer 2 addressing ARP Switching overview
Planning and Cabling Networks
Routed Protocols Media requirements for LANs Device management Cabling types and standards Design and plan the network - addressing scheme and topology
