Networking Fundamentals: Design and Configuration

Understanding how computers communicate is the bedrock of modern IT infrastructure. If you are starting your journey in system administration or IT support, mastering networking concepts is crucial. This course provides a solid foundation in computer networking, enabling you to confidently design, configure, and troubleshoot basic network environments using industry-standard models and practices. What you'll learn: * Understand the structure and function of the OSI and TCP/IP models and common network protocols. * Master IP addressing, subnetting (IPv4 and IPv6), and the role of DNS and DHCP services. * Configure fundamental network devices, including switches and routers, and understand basic routing principles. * Practice essential network administration tasks, including monitoring, security hardening, and basic troubleshooting techniques. * Apply foundational principles of modern security, such as zero-trust architecture concepts, to network design. * Learn basic infrastructure configuration patterns for managing network device settings efficiently. We start with core terminology and data transmission concepts, then move through the layers of the network stack, culminating in practical exercises focused on configuration and basic administration. This course is designed for absolute beginners in IT, students, or professionals looking to transition into network administration or system support roles. No prior networking experience is required.
