About this course

Have you ever wondered what happens the moment you click a link, or how information travels across the globe in milliseconds? Understanding the basics of computer networks is essential for navigating the digital world with confidence. This course breaks down complex networking technology into clear, approachable explanations, focusing on real-world examples rather than dense jargon. You will gain a solid foundation in how devices communicate, ensuring you understand the infrastructure that supports all modern software and applications. What you'll learn: * Understand the fundamental layers (OSI and TCP/IP models) that govern all network communication. * Master the core concepts of IP addressing, routing, and domain name resolution (DNS). * Learn how common network services like Wi-Fi, Ethernet, and basic firewalls operate in your home and office. * Apply basic security principles by understanding modern concepts like zero-trust architecture and secure connection protocols. * Configure and troubleshoot simple connectivity issues using foundational network commands and diagnostic tools. The course begins by defining key terminology and explaining the foundational models of networking. It then moves into practical applications, covering how data is packaged, routed, and secured across local and global networks. This course is specifically designed for absolute beginners and non-technical users who want a simple, jargon-free introduction to computer networking. No prior technical knowledge is required.
