Data representation, text, sound and images using ASCII, EXTENDED ASCII and UNICODE
In this video we will learn text presentation using ASCII, EXTENDED ASCII and UNICODE, using denary and hexadecimal coding methods for o levels
ASCII is a character encoding system that only includes up to 256 characters, primarily composed of English letters, numbers, and symbols. It uses up to eight bits to represent each character. In contrast, Unicode is a much larger encoding standard that includes over 149,000 characters. It can represent nearly every modern script and language in the world.
Unicode supports special characters such as mathematical symbols, musical notation, and emojis, which are not included in ASCII. Most importantly, the number of supported characters can be expanded in the future, as required.
