Networking underpins everything from cloud infrastructure to security work, and starting without the basics leaves gaps that surface later. This short course covers the essential concepts, from what a network actually is through topologies, TCP/IP, server types, IP and MAC addressing, and the OSI and DOD models.

This Course Offers

• What a computer network is and the different network types you will encounter
• Network topology explained, including the various topology types and how they affect reliability and cost
• Core networking terms and components including switches and firewalls
• Server types and their roles within network environments
• Addressing fundamentals covering IP and MAC addresses, plus the OSI model and DOD model for understanding how data moves
