In this module, we will dive into the essential networking models—the TCP/IP and OSI models. You’ll learn why models are crucial for comprehending communication in networks. We’ll also introduce Wireshark to capture network traffic and examine the various protocols used in different layers, providing a thorough understanding of data transmission processes.

In this module, we will break down the fundamental units of digital data—bits and bytes—and their significance in network communication. You will learn about Protocol Data Units (PDUs) and how they operate across different network layers. We will also cover how data is encapsulated and decapsulated during transmission, ensuring proper communication.

In this module, we will explore Ethernet, one of the most common methods for wired network communication. You'll understand the various types of network media and the function of Network Interface Controllers (NICs). We’ll also delve into the details of MAC addresses and their importance in identifying devices on a network.

In this module, we will examine key network properties such as bandwidth, throughput, latency, and jitter. You will learn how these factors influence network performance and gain practical experience measuring these characteristics using tools like Ping to diagnose and troubleshoot network issues.

In this module, we will explore the Data Link Layer, focusing on the role of network switches in data forwarding. We will break down the structure of Ethernet frames and discuss various communication types like unicast, multicast, and broadcast. You'll also learn about collision handling mechanisms and the negotiation of network device settings.

In this module, we will focus on the Network Layer and the crucial role routers play in network communication. You will gain an understanding of IP addressing (both IPv4 and IPv6) and how routers manage data traffic between local and wide area networks (LANs and WANs). By the end of the module, you'll have a clear understanding of how routers interconnect networks for global communication.
