Halting refers to the process of stopping or pausing an action or operation. In computer science, it often relates to the concept of a program or algorithm that ceases to execute. The ability to determine whether a program will eventually stop running or continue indefinitely is a fundamental question in the field. The Halting Problem, introduced by Alan Turing, is a famous example that demonstrates the limitations of computation. It states that there is no general algorithm that can solve the problem for all possible program-input pairs, meaning some programs cannot be predicted to halt or run forever.
