The Network Protocols and Architecture Level 3 Advanced Diploma is an expertly structured course tailored for individuals looking to deepen their understanding of how modern networks function, from foundational protocols to sophisticated architectural frameworks. This course is perfect for beginners looking to build a career in IT, as well as for current professionals seeking to upskill and stay relevant in a fast-changing digital environment.

The course begins with an introduction to networking fundamentals, where learners explore basic concepts such as how data is transmitted, common networking models like the OSI and TCP/IP models, and various types of network topologies used in real-world settings. This foundation prepares learners to navigate more technical content with ease.

Moving into the heart of networking, students will study core network protocols, with a focus on the TCP/IP protocol suite, IP addressing and subnetting, and routing protocols such as OSPF and BGP. This module also covers essential application layer protocols like HTTP, DNS, FTP, and SMTP—protocols that underpin daily online activity and digital communication.

In the Network Architecture module, students gain insight into the planning and design of network infrastructure, including network devices and their functions, and learn to implement security architecture to protect data integrity. The module concludes with a look at emerging technologies, such as SDN (Software-Defined Networking), IPv6, and cloud-based architecture.

To ensure practical readiness, the course ends with a comprehensive focus on network troubleshooting and management. Learners explore diagnostic techniques, tools for performance monitoring, and configuration management practices vital for maintaining efficient and secure networks in both enterprise and small business environments.
