Introduction to Networking Solved Exam Questions
Course Introduction
Introduction to Networking provides a comprehensive overview of the fundamental concepts, technologies, and protocols that enable computer networks to function. Students will explore the basics of data communication, network topologies, and networking hardware such as routers and switches. The course delves into key protocols like TCP/IP, addresses network models like OSI and the Internet Protocol Suite, and introduces concepts such as IP addressing, subnetting, and wireless networking basics. Emphasis is placed on understanding how local area networks (LANs), wide area networks (WANs), and the Internet facilitate data exchange and connectivity in a digital world. Through practical activities and real-world examples, students gain foundational skills necessary for further study or entry-level roles in the networking field.
