Computer Networks
Final Exam
Course Introduction
Computer Networks is a foundational course that explores the principles, technologies, and protocols that enable communication between computer systems across various networks. Students will learn about network architectures, data transmission methods, network hardware, and the layered approach to networking, with an emphasis on the OSI and TCP/IP models. Key topics include packet switching, addressing and routing, network security, wireless and wired network technologies, error detection and correction, and emerging trends such as cloud networking and the Internet of Things (IoT). Through practical assignments and hands-on labs, students develop the skills to analyze, design, configure, and troubleshoot modern computer networks.
