Summary

Computers represent characters using binary because it's the language they understand best. Binary uses only 0s and 1s, which the computer can process quickly. Each character is assigned a unique binary code, like a secret password.

For instance, the ASCII character set is a basic one that covers English characters like letters, numbers, and symbols. It assigns each character a 7 or 8-digit binary code. For example, the letter "A" is represented as 01000001 in ASCII.

To represent more characters, the Extended ASCII set uses 8 or more digits in binary. It includes special characters and accents used in different languages.

Additionally, character sets are crucial for emojis. As computers can't understand pictures directly, emojis are assigned unique codes, allowing them to be translated into binary and displayed on our screens.
