Introduction to Networking Question Bank
Course Introduction
Introduction to Networking provides students with a foundational understanding of how computer networks operate, exploring the core concepts, protocols, and architectures that enable devices to communicate and share resources. Through the study of topics such as the OSI and TCP/IP models, network devices, addressing and routing, and common networking services, students will develop the skills necessary to analyze network structures, identify key components, and understand data transmission processes. Practical exercises and real-world scenarios will enhance their ability to troubleshoot basic networking issues and prepare them for further study or entry-level roles in IT networking environments.
