This diploma course is designed to provide a comprehensive understanding of networking and local area networks. Starting with network terminology, we explain serial data transfer and internet protocol (IP) addresses, and explore the most common types of networks. The course then delves into the ‘open systems interconnection’ (OSI) model, demonstrating how its layers guide network traffic. Both wired and wireless networks are covered, as well as the tools used to manage and troubleshoot them.

Dynamic host configuration protocol (DHCP) is a client/server protocol that allows client computers to obtain IP addresses automatically. The course outlines the information that can be obtained from IP addresses using DHCP, as well as the benefits of doing so. Additionally, we investigate ‘discovery, offer, request, acknowledge’ (DORA) discovery and ‘automatic private IP addressing’ (APIPA), a service used for assigning unique IP addresses to small office or home networks without deploying the DHCP service.

Setting up a network can significantly enhance a business’s ability to share information and resources, making it a fast and reliable way of communication. This course provides a deep understanding of different types of LANs and WANs used in networks, as well as the protocols used to secure communications and preserve network security. This diploma course is highly suitable for individuals working in the field of information technology who are looking to improve their computer skills and take the next step in their career.
