👉 Existed computing, also known as classical computing, is a model of computation that uses binary logic and follows the principles of digital information processing. It relies on discrete states, typically represented by bits (0s and 1s), to perform operations through logic gates. These gates execute basic arithmetic and logical functions, enabling the construction of more complex circuits and systems like CPUs (Central Processing Units) and memory units. Classical computers process information sequentially, executing instructions one after another, and they are limited by the speed of electronic signals and the physical constraints of their hardware. Despite these limitations, existing computing has revolutionized numerous fields, including science, engineering, finance, and communication, by providing efficient and reliable methods for data processing, storage, and manipulation.
