This module introduces students to the fundamentals of networking. On completion of this module the student will understand how protocols work together to achieve data communications and the lifecycle of a packet as it traverses a computer network. As part of this, a computer network, its architecture, protocol stacks and the process of data segmentation and encapsulation are introduced. In addition, the principles and structure of Internet Protocol (IP) addressing and sub-networking are explored with students building and configuring a basic network as well as utilising common network utilities.
