Computer Network

This course provides a comprehensive introduction to the principles, architectures, and protocols that form the foundation of modern computer networks. Students will explore the layered Internet protocol stack, from physical transmission to application services, covering key topics such as LAN technologies (Ethernet, Wi-Fi), network layer addressing (IPv4, subnetting, routing), reliable transport (TCP), and critical application protocols (DNS, HTTP). Through a combination of theoretical concepts and practical simulation exercises, students will learn to analyze network performance, design network addressing schemes, and understand the functions of core networking devices like routers and switches.
