Session 1 - Introduction to Binary Digits

This session introduces you to the use of binary digits to represent basic images and the key terms for capacity. During the session you will investigate 4-bit binary numbers and look at the patterns in the numbers.

1. Open Slides and read through slides 2 and 3 to get an understanding of the session that you are working through. Make sure you have a good look at the information on slide 2 about a computer being able to use 2 states, 1 and 0.
2. Work through slides 4-6 regarding one-bit colour. This will tell you how many colours can be represented by a single bit. Record what you understand about one-bit colour in the workbook.
3. Carry out some research into the common names for different storage amounts. Find out what each term means e.g. how many kilobytes are stored in a megabyte. See if you can find an answer to the last question on slide 7. Write all your answers in the workbook.
4. Slides 8 and 9 are for Task 3 in your workbook. Read the notes before each question carefully before trying to answer them in your workbook. The numbers you are to convert to 4-bit binary are on slide 9.

All the answers to the tasks can be found in the answers document.
