Character Encoding and Binary Representation

The video tutorial explains how computers represent characters using binary codes and introduces the concept of character sets. It covers the basics of binary representation, the need for multiple bits to represent a wide range of characters, and the development of character sets like ASCII and Unicode. ASCII, a 7-bit character set, was extended to include more characters, while Unicode provides a comprehensive standard for international and multilingual character representation. The video emphasizes the importance of standardized character sets for consistent data interpretation across different systems.

Why do computers need binary codes to represent characters?

• Because binary is easier to read.

• Because computers can only understand binary.

• Because binary codes are shorter.

• Because binary is a universal language.
