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

Configuring and Testing Your Network

 Cisco Device IOS Cisco Device CLI Using common testing utilities
