Learning Intention I will learn how computers store text

Storing Text Computers use binary to store characters A character is a letter, number or symbol from the keyboard. Characters include: digits (0-9) letters (A-Z,a-z) special characters (,#@;* etc)

Storing Text The list of characters a computer can process and store is called the character set. Each character is given a unique code number using 8-bits (1 byte)

Storing Text Most popular form of code is ASCII (ask-eee) – American Standard Code for Information Interchange. Extended ASCII uses 28 different codes = 256 different codes. e.g. 01000001 = 65 = A 01000010 = 66 = B

Success Criteria I can convert from text to binary and vice-versa.
