👉 Necessary computing refers to the fundamental computational processes and operations that are essential for the functioning of any system, whether it's a computer, a biological organism, or even a theoretical construct. It encompasses the basic algorithms, data structures, and logical operations that enable systems to process information, make decisions, and perform tasks. In essence, necessary computing is the bedrock upon which all higher-level computations are built; without it, no system could execute instructions or solve problems. This concept is crucial in understanding the limits and capabilities of computational systems, as it defines what can be computed given the resources available.
