Unit 2: Wired and wireless networks

Specification J276 from 2016



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 1.4 and 1.5 of the OCR GCSE J276 Computing specification. Each lesson contains a worksheet to be done in class to consolidate students’ knowledge and understanding, as well as a homework sheet to give them plenty of practice in answering exam-type questions.

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 LAN network topologies and Ethernet, with further material on virtual networking. Wireless networking, frequencies and encryption are covered in a subsequent lesson. 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.
