Computer networks are the driving force behind the evolution of computer systems and allow users to access data, hardware, and services regardless of their location. Being knowledgeable about the underlying principles of networking is of vital importance to all IT professionals. Networking is an environment that is increasingly complex and under continuous development.

Complex computer networking has connected the world by groups of small networks through internet links to support global communications. It supports access to digital information anytime, anywhere, using many applications like email, audio, and video transmission, including the World Wide Web, and this has opened the floodgates to the availability of information.
This unit aims to give students a wider background knowledge of computer networking essentials, how they operate, protocols, standards, security considerations, and the prototypes associated with a range of networking technologies. Students will explore a range of hardware, with related software, and will configure and install these to gain knowledge of networking systems. A range of networking technologies will be explored to deliver a fundamental knowledge of Local Area Networking (LAN), Wide Area Networking (WAN), and their evolution to form large-scale networks.

Students will also explore the protocol methodologies related to IP data networks. On successful completion of this unit, students will have gained the knowledge and skills needed to successfully install, operate, and troubleshoot a small network; and the operation of IP data networks, routers, switching technologies, IP routing technologies, IP services, and basic troubleshooting. Supporting a range of units in the Higher National suite, this unit underpins the principles of networks for all and enables students to work towards their studies in vendor units, if applicable. Students will develop skills such as communication literacy, critical thinking, analysis, reasoning, and interpretation, which are crucial for gaining employment and developing academic competence.
