Summary

This unit is subdivided into six topics (plus a test) covering the theoretical content of Section 3.7 of the AQA AS Level specification 7516. The unit begins by describing the internal hardware components of a computer, different architectures and the stored program concept. The fetch-execute cycle is explained in a detailed and practical way including the role of the major components and dedicated registers used by the processor. Instruction sets and addressing are covered along with basic machine code and assembly language operations. The function and characteristics of various external hardware devices and storage methods are explained in the final two topics.
