Understanding ASCII and Unicode

The video tutorial covers the conversion of decimal numbers to binary and the encoding of characters using ASCII and Unicode. It explains how ASCII uses 7 bits to represent characters and its limitations in representing a wide range of symbols and languages. The tutorial introduces Unicode as a solution, capable of using more bits to support a vast array of characters, including emojis. A practical demonstration using Notepad illustrates the difference in file size when saving characters in ASCII and Unicode formats.
