The Computer Networks course introduces students to the fundamental concepts, protocols, and technologies that form the backbone of modern communication systems. This course explores the design, implementation, and management of computer networks, with a focus on both theoretical and practical aspects. Students will learn about network architectures, communication protocols, network devices, and various technologies used in local area networks (LAN), wide area networks (WAN), and the internet.
Key topics covered include:
- Network Models and Protocols: In-depth understanding of the OSI and TCP/IP models, as well as how different layers interact with protocols like TCP, UDP, IP, and HTTP.
- Network Topologies: Study of common network layouts including star, bus, ring, mesh, and hybrid topologies, and their respective advantages and disadvantages.
- Routing and Switching: Detailed exploration of routing algorithms, switches, and routers, including static and dynamic routing, as well as the role of protocols such as RIP, OSPF, and BGP.
- IP Addressing and Subnetting: Comprehensive coverage of IPv4 and IPv6 addressing, subnetting, supernetting, and CIDR (Classless Inter-Domain Routing).
- Wireless Networks: Examination of wireless technologies, including Wi-Fi, Bluetooth, and cellular networks, and their integration into modern networks.
- Network Security: Introduction to security protocols, firewalls, VPNs, and encryption techniques to safeguard data and prevent unauthorized access.
- Network Troubleshooting: Practical approaches to diagnosing and resolving network issues, with the use of tools such as ping, traceroute, and Wireshark.
Throughout the course, students will develop hands-on skills through practical exercises, labs, and assignments that involve configuring network devices, implementing protocols, and analyzing network traffic. Upon completion, students will be equipped with the knowledge and skills to manage and troubleshoot computer networks in real-world environments, laying the foundation for advanced study or careers in network administration, cybersecurity, and systems engineering.
Prerequisites: Basic knowledge of computer systems, operating systems, and programming concepts.
