This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. In this in-depth course, you'll master the essential networking and troubleshooting skills required in the IT industry. Starting with foundational concepts such as networking protocols, operating system networking, and troubleshooting techniques, the course will guide you through tools and strategies to diagnose and resolve issues effectively. You will explore a wide range of technologies from TCP/IP to wireless networking, as well as hands-on practices in solving common network and system issues that you’ll encounter as an IT technician. The journey begins with command-line interface (CLI) techniques, empowering you to navigate through directories, work with files, and manage system resources. You'll gain expertise in advanced commands for both Windows and Linux environments and even get an introduction to scripting for automating tasks. From there, the course dives into key networking concepts like DNS, IP addressing, routers, and firewalls, providing you with a deep understanding of how systems communicate over the network. Troubleshooting becomes a crucial aspect of your learning, with extensive coverage of various repair tools, recovery environments, and diagnostic utilities. The course is perfect for IT enthusiasts, aspiring network administrators, and anyone eager to understand networking fundamentals. It’s ideal for beginners, with no prior networking experience required, though an understanding of basic computing can be helpful. By the end, you’ll be proficient in diagnosing networking issues, performing system repairs, and setting up both local and wide area networks. By the end of the course, you will be able to troubleshoot and resolve common networking issues, configure and manage routers, firewalls, and wireless networks, as well as use command-line tools effectively for a range of system tasks. You will also gain confidence in setting up virtual LANs (VLANs) and managing IP addressing and NAT for efficient network communication.
