Data Communications and Networking 1: LAN Architecture and Protocols

About Course

Welcome to Data Communications and Networking 1, your foundational stepping stone into the world of IT infrastructure. In today’s hyper-connected digital landscape, understanding how data travels across networks is a critical and highly sought-after skill.

This course covers the fundamentals of configuring and implementing Local Area Networks (LAN). You will be guided through the historical evolution of networks all the way to modern-day network security implementations. Whether you are aiming to become a network administrator, an IT support specialist, or a cybersecurity analyst, you will learn exactly how to design, configure, troubleshoot, and implement LAN setups using enterprise routers for small to medium-sized businesses.

By the end of this term, you will be able to:
Understand the fundamental concepts and core components of data communication.
Describe and compare different types of network architectures and physical topologies (bus, star, ring, mesh).
Analyze and explain the operation of standard networking protocols, including TCP/IP and the OSI model.
Design and implement basic network configurations and IP subnetting.
Evaluate the performance constraints and security issues inherent in data communication systems.

Physical Connectivity and the Data Link Layer
Students will explore the physical construction of networks, including various topologies and transmission media, alongside the Data Link layer's role in node-to-node communication and Ethernet standards.

Network Routing and Transport Protocols
This section dives into the mechanics of moving data across multiple networks. It covers IP addressing, subnetting, routing protocols, and how the Transport layer ensures reliable or rapid data delivery via TCP and UDP.

Application Services and Network Security
The final period focuses on the upper-level protocols that applications use to communicate over the network, followed by a critical introduction to securing those communications against vulnerabilities.
