What is the Church-Turing thesis?

The Church-Turing thesis is a hypothesis that states that any function that can be effectively computed by an algorithm can be computed by a Turing machine. It suggests that Turing machines are capable of solving any problem that can be solved by an algorithm, regardless of the programming language or computational model used. The thesis is named after mathematician Alonzo Church and computer scientist Alan Turing, who independently proposed similar ideas in the 1930s.
