Comprehensive Computer Studies
This text book was written to support the teaching of Computer Studies when the subject was introduced into schools in the early 1980s. Whilst the programming languages of CESIL and BASIC are rarely used in school, the principles of computing they are used to convey could still have some relevance today. The topics covered in the book include the overall structure of the computer, computer logic, types of programming language, operating systems and data processing.
The coding and storing data section explains how arithmetic using the binary number system is conducted, including how to represent fractions using binary. The section covering computer logic explores the use of logic gates including AND gates, OR gates, NOT gates, truth tables and circuits. Computer arithmetic considers the half adder, the full adder, the parallel adder, serial adder, subtraction, multiplication and division.
Sections relating to the history of computers, the social effects of computers and the people who work with computers put into perspective the changes in computing that have taken place in recent years.
