👉 Theory of Computation, or simply Computing, is a branch of computer science that explores the fundamental capabilities and limitations of computation. It investigates what problems can be solved using algorithms and what resources (like time and memory) are required to solve them. Central to this field are concepts like Turing machines, which serve as theoretical models of computation, and complexity classes, such as P and NP, that categorize problems based on their solvability and efficiency. Computing also delves into areas like automata theory, which studies abstract machines that process input symbols, and formal languages, which define the structure of strings of symbols. This theoretical framework not only helps in understanding the capabilities of modern computers but also guides the development of new computational models and algorithms.
