Good morning year 9,
Next week you will have a test on Data representation. For this test you will need to study how text, numbers, images and sound is represented in binary. Needed resources:
Text book: Unit 2 (excluding chapter 2.1)
All your classwork/Homework (This includes theory covered during the teach ICT class as well as the PowerPoint presentation class)
All the key terms given
Theory summary (Does not include all theory)
You need to know how to convert text to binary and back. (The ASCII table)
You need to know how to convert numbers to binary using both methods
You need to know how to convert images to binary and back.
You need to know how to convert sound to binary and back.
As You notice some of what you need to is a repetition of the last half term. I will not ask you any theoretical questions about converting numbers and text. You will only need to know how to convert them. This does not apply for images and sound. For this you will need to know both the theory as well as application.
Test will be given on:
9Y – 11th of December
9X – 12th of December
