In this module, we will explore the two primary models used to describe and troubleshoot network interactions. We’ll dive into the OSI model, its seven layers, and how these concepts are essential for understanding networking. By mastering these models, you will gain a deeper understanding of how data flows across networks and how to troubleshoot various network issues efficiently.

In this module, we will examine the physical components of networking, including cabling types and network topologies. You’ll learn about the strengths and weaknesses of various cabling systems, such as coaxial, twisted pair, and fiber optics, and understand how network topologies like star, mesh, and hybrid influence data flow and network performance. This knowledge is essential for building efficient and reliable network infrastructures.

In this module, we will focus on Ethernet technology, one of the most fundamental networking protocols. You’ll learn about Ethernet frames, their structure, and how they help transmit data over networks. Additionally, we’ll cover the differences between networking devices like hubs and switches, ensuring you understand how to manage and expand Ethernet-based networks effectively.

In this module, we will dive into the standards that define Ethernet speeds and distances, from the basic 100BaseT to the faster 10GBase Ethernet. You’ll also learn about transceivers and their role in connecting different network segments. Finally, we’ll explore how to identify and resolve common Ethernet networking issues, ensuring smooth and efficient operations.

In this module, we will guide you through the process of installing and configuring a physical network, covering everything from structured cabling to equipment rooms. You'll learn how to properly terminate cables, test their integrity, and troubleshoot common installation issues. This section is designed to give you hands-on skills for building and maintaining a physical network infrastructure.

In this module, we will explore the core components of TCP/IP networking, focusing on IP addressing, ARP, and subnetting techniques. You’ll gain a deep understanding of how IP addresses are structured and used within networks and how subnetting allows for efficient routing and management of IP space. By the end of this section, you'll be equipped with the skills to troubleshoot and optimize IP configurations in real-world networks.
