In this module, you will describe the Open Systems Interconnection (OSI) model and identify the functions performed by each of its seven layers. You will explain how the OSI framework supports interoperability between network devices and provides a foundation for understanding network communication and troubleshooting.

In this module, you will describe the TCP/IP model and compare it with the OSI model. You will identify the functions of the TCP/IP layers and explain the differences between Layer 2 and Layer 3 networks and their roles in supporting data communication.

In this module, you will explain how IP addressing, packet forwarding, routing, and load balancing support network communication. You will recognize the purpose of routing and load balancing and describe how network devices direct traffic efficiently between destinations.

In this module, you will compare IPv4 and IPv6 addressing schemes and identify the key differences between them. You will explain the limitations of IPv4, the need for IPv6, and the advantages provided by modern addressing standards.

In this module, you will describe the role of the transport layer in end-to-end communication and compare the characteristics of Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). You will recognize how these protocols support different networking requirements and communication scenarios.

In this module, you will describe common network segmentation approaches and explain their benefits for performance, security, and manageability. You will identify the roles of technologies such as VLANs, VXLANs, and Virtual Routing and Forwarding (VRF) in creating logical network boundaries.

In this module, you will describe how wireless networking technologies enable communication across devices and environments. You will identify key wireless standards and explain the capabilities of technologies such as Wi-Fi, Wi-Fi 6E, and 5G in supporting modern connectivity needs.

In this module, you will review the key concepts covered throughout the course, including network categories, network models, IP addressing, routing, transport protocols, network segmentation, and wireless technologies. You will demonstrate your understanding of these topics by completing the graded assessment and applying the knowledge gained throughout the course.
