Learning Objectives:

the use of binary codes to represent characters
the term ‘character-set’

Know how Binary is used to represent characters
Define ASCII, character set and Unicode are
Apply knowledge to demonstrate skills

Lesson Overview

Resources

Starter:
Look at the keyboard in front of you. Each character requires one byte of memory.

How much memory would it require to store each character?
How many bits are required to represent all the charters?

In this lesson you will learn how Binary is used to represent characters. ASCII is the American Standard Code for Information Interchange which is used to convert between Binary and characters.

Plenary:
Complete the MCQs and then peer mark, which questions did you get wrong and why? Write down the answer / correct response in your book.
