Y9

Summary

 

 In this unit you will learn the theory on input and output devices.  You will also learn the Input-Process-Output sequence and the Fetch-Decode-Execute cycle through practical activities.

 

Lessons will also help you to understaand some simple binary to decimal conversion and vice versa, and learn how text characters are represented using the ASCII code. This will be followed by some simple binary addition.

 

The final part of the unit will enable you to develop knowledge on how storage devices represent data using binary patterns and physically save these patterns.
