Summary

This unit is subdivided into six learning hours spread across six lessons, plus a test, in order to fit with most school timetables. It is a theoretical unit covering Topic 4 of the Edexcel GCSE (9-1) 1CP2 Computer Science 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 starts with a description of how the Internet is structured, and what is meant by the World Wide Web. It also covers wireless networks. Lesson 2 covers different types of network (LAN and WAN) and different network topologies, and Lesson 3 describes the role of different protocols and the layers in the TCP/IP protocol stack. The lessons move on to network security issues and threats, with a look at different ways our networks can be made more secure.

At the end of the unit, students sit an assessment test comprising questions similar to those found on the Edexcel exam paper.
