The unit is subdivided into six learning hours spread across six lessons, including a test, in order to fit with most school timetables. It is a theoretical unit covering Section 1.3 of the latest OCR GCSE J277 Computing specification.

The unit begins by explaining the Internet and IP addressing, with practical exercises to help students understand the role of packet switching and DNS services. The lessons move on to look at star and mesh LAN network topologies and Ethernet. Wireless networking and encryption are covered in subsequent lessons. Client-server networks and hosting are addressed with a final lesson describing common protocols and the concept of layers. At the end of the unit, students sit an assessment test comprising questions similar to those found on the OCR exam paper.
