Diploma in Computer Networking

Course description

This diploma course introduces you to the architecture and protocols used in network security. We explain the structure and function of local area networks (LANs) and wide area networks (WANs) and examine key devices like hubs, switches and routers. These allow for efficient communication through a network and this course teaches you everything you need to know to keep that data safe from prying eyes, an invaluable skill in the Information Age.

This diploma course discusses the basics of networking and local area networks. We lay out network terminology and explain serial data transfer and internet protocol (IP) addresses as we examine the most common types of network. We study the ‘open systems interconnection’ (OSI) model to illustrate how its layers guide the flow of network traffic. We cover wired and wireless networks and the tools used to manage and troubleshoot them.

Dynamic host configuration protocol (DHCP) is a client/server protocol that enables configured client computers to obtain IP addresses automatically. We outline what information can be obtained from IP addresses using DHCP and the benefits of doing so. We then investigate ‘discovery, offer, request, acknowledge’ (DORA) discovery and ‘automatic private IP addressing’ (APIPA), which is a service for assigning unique IP addresses to small office or home networks without deploying the DHCP service.

Setting up a network can help a business make the most of its computer systems and equipment. It is a fast and reliable way of sharing information and resources. This course provides a deep understanding of the different types of LANs and WANs found in networks and the protocols used to secure communications and preserve network security. This diploma course suits anyone working in the field of information technology so sign up to polish your computer skills and take the next step in your career.
