Code page

A code page is a way of representing characters (like the letters in the alphabet) using a computer. It is like a secret code: the code page assigns a code number to each letter, so that the computer can show that character. For example, the code number for the letter "A" might be 65, and the code number for the letter "B" might be 66. When the computer wants to show the letter "A" on the screen, it looks at the code page and sees that "A" has the code number 65, so it sends the number 65 to the screen. The screen then knows that it has to show the letter "A".
