Universal Turing Machine

A Universal Turing Machine is a theoretical device that can simulate any other Turing machine's computation. Think of it as a flexible computer with an extensive set of instructions and a special tape acting as memory. By adjusting its input and instructions, it can perform any algorithm or problem-solving process that any other machine can do. This concept helps us understand the fundamental capabilities of computers, showing that a single, adaptable machine can perform an infinite variety of tasks, provided it's given the right instructions and data.
