Computation means a set of actions that ensure the automation of information processing. To ensure automatic processing, we need to use technology, which means a programmable device. Today it is the binary computer for sure. Anyway, we must ensure that this processing engine behaves following an appropriate algorithm. The algorithm is again information because it is a piece of knowledge on how to solve the problem. Hence, it is an abstraction that will be useful in the computation process if the algorithm is represented in binary form.
What is a binary form representing an algorithm?
