Often computers are viewed as machines that run algorithms. This view of computers covers a vast range of devices, from simple computers that perform limited and specific computations (for example, a computer found in a wristwatch) to supercomputers, which are groups of computers linked together in homogeneous and heterogeneous clusters and serving a vast array of computational needs. In between these extremes are a variety of machines from personal computers to embedded devices dedicated to serving a variety of functions. Let us call the perspective of computers as machines that run algorithms “mechanistic.” Through the mechanistic lens, the computer is an artifact, coming from the Latin words arte, which means “skill” or “craft,” and facere, which means to do or make. An artifact is that thing is skillfully or artfully made; and the computer, then, is a skillfully made machine for purposes of computation.
