Summary

This unit is subdivided into seven lessons (plus a test). It is a theoretical unit covering all of Topic 4: Computers of the Edexcel GCSE (9-1) Computer Science specification 1CP1. The first three lessons cover the components of a computer system and their function, including the role of the CPU components. A lesson on Boolean logic is followed by lessons on the operating system, utility and simulation software. The final lesson describes high-level and low-level programming languages, the use of an assembler and the functions of a compiler and interpreter, giving the advantages and disadvantages of each.

What people say...

All the resources I have brought from you previously have been excellent and a great help in delivering my lessons for BTEC Level 2 and GCSE. 

Theresa Brown. Computer Science Teacher, Paget High School

PG Online resources are very well planned and easy to use. Inspection copies are also useful as this enables me to make better choices with our limited budgets.
