Fundamentals of Networking and Cisco Devices

This course is designed to lay the foundation for your networking knowledge and help you become proficient in handling Cisco devices. Starting with an introduction to networking principles, you’ll explore core topics like host-to-host communications, IP addressing, and the OSI model. The content is structured to ensure you understand how different layers of a network interact and how data is transmitted between devices. As you move forward, you’ll gain hands-on experience with Cisco Packet Tracer, learning to set up labs and configure Cisco IOS. The course also covers essential topics such as navigating the Cisco IOS interface, understanding TCP/IP protocols, and performing basic configuration and troubleshooting on routers and switches. Practical labs provide you with the real-world scenarios necessary to master these concepts. In addition to networking theory, this course covers Cisco device management techniques, including upgrading IOS, performing factory resets, and recovering passwords. By the end of the course, you’ll be ready to manage Cisco network devices, troubleshoot common issues, and set up robust networks, laying the groundwork for further studies in CCNA certification. This course is ideal for beginners in networking and IT professionals seeking foundational Cisco device knowledge. No prior networking experience is required, but a basic understanding of computers is helpful.
