Summary

The unit is subdivided into six learning hours spread across six lessons, plus a test, in order to fit with most school timetables. The test is provided with IGCSE® exam-style questions to assess understanding across all lessons in the unit. It is a theoretical unit covering the relevant sections 1.2 to 1.4 of the Cambridge IGCSE® 0478 / 0984 and O Level 2210 Computer Science specification.

The unit begins by covering the purpose and function of operating systems software including the need for interrupts. The distinction between freeware, shareware and free software is explained and the need for high- and low-level languages and the use of compilers and interpreters is covered in a third lesson. The final three lessons on security cover phishing, pharming and DoS attacks before looking at online data security and encryption. Firewalls, proxy servers and SSL and TLS security protocols are also covered. Real-life examples in worksheets and homework are used to cover all security aspects including online shopping, and banking. In the seventh lesson, students sit a final assessment test written in the style of real IGCSE exam-style questions.

What people say...

The judges were very impressed with the high quality of these learning resources from PG Online.

Each unit is carefully prepared and beautifully illustrated. The content is directly related to the curriculum and is in an easy to access format for all learners.

Judges. Education Resource Awards

One of the major reasons I love PG Online resources is the fact that they are simple, editable powerpoint and Word documents, not tied down with non-editable pdfs.
