Network Fundamentals 1
Start your networking journey here. Master the physical and conceptual foundations, including cabling, hardware devices, binary math, and the essential OSI and TCP/IP models. 8 rooms available
Network Overview
Begin your journey into networking by understanding the core concepts of connectivity. Explore how computers communicate, the basic components of a network, and the essential infrastructure that enables global data exchange.
Network Topologies
Examine the physical and logical layouts of modern networks. Understand different architecture types like Star, Mesh, and Bus, and learn how topology choice impacts network performance, redundancy, and scalability.
Network Cabling
Explore the physical layer of connectivity. Learn about different types of network media, including copper Ethernet cables and fiber optics, and understand the standards and limitations of physical transmission hardware.
Network Devices
Identify the essential hardware that powers a network. Understand the specific roles of routers, switches, hubs, and access points, and learn how these devices work together to route and manage data traffic.
OSI Model
Deep dive into the 7-layer Open Systems Interconnection model. Learn how data is encapsulated and processed as it moves from the application layer down to the physical wire and back up at the destination.
TCP IP Model
Understand the practical 4-layer framework that powers the modern internet. Compare the TCP/IP suite with the OSI model and learn how protocols like TCP and UDP function within this architecture.
Ports and Services
Understand how applications identify specific communication channels. Explore common well-known ports and learn how port numbers allow multiple services to run simultaneously on a single IP address.
Network Protocols
Learn the standard languages used by computers to talk to each other. Examine the rules and procedures that govern data exchange across the internet and local area networks.
