This course provides a comprehensive introduction to the fundamentals of computer networking and the Internet. It begins by exploring the basic principles of digital communication, including how data is encoded and transmitted between devices. Key concepts such as IP addressing and subnetting are introduced to explain how devices are uniquely identified and organized within networks. The course also examines the role of routing and Network Address Translation (NAT) in directing data across interconnected systems, as well as the functions of essential network protocols like DHCP, ARP, and Ethernet in enabling device communication within local networks.
Building on these foundations, the course delves into higher-level networking concepts, including the Domain Name System (DNS), which translates human-readable web addresses into machine-readable IP addresses. It covers the differences between TCP and UDP, the two main transport layer protocols, highlighting their respective uses for reliable and fast data transmission. Students are introduced to modern networking technologies such as Content Delivery Networks (CDNs), HTTP, email protocols, and Software-Defined Networking (SDN), which allow for more flexible and efficient network management. The course concludes with an overview of data centre architecture and wireless networking, providing insight into the infrastructure that supports today’s cloud services and mobile connectivity.
