Classical computer science has linked human computing and machine

computing in the so-called Church-Turing thesis: Everything that a human being

can compute can be computed by a machine. According to this thesis, our intui-

tive understanding of computation refers to the set of computations that can be

formally prescribed. Closely related to this idea is the concept of an algorithm.

An algorithm is a set of rules or instructions for getting a desired output from

a given input. The word “algorithm” originated in the Middle East. Curiously

enough it comes from the Latin version of the last name of the Persian scholar Abu

Jafar Mohammed ibn Musa al-Khowaresmi (Algorithmi) whose textbook on

arithmetic (825 A.D.) employed for the first time Hindu positional decimal notation

and gave birth to algebra as an independent branch of mathematics. It was trans-

lated into Latin in the 12

th

century and had a great influence for many centuries on

the development of computing procedures. The name of the textbook’s author be-

came associated with computations in general and used as a term “algorithm”.

Personal computing is a partnership between the person and the computer.

Believe it or not, a personal computer is easier to operate than a car. It’s even

easier to operate than a telephone, which comes with no instructions at all. Sud-

denly, personal computers invaded our world. It’s not surprising that it takes

most of us a while to get comfortable with a comparatively new technology that

so quickly arrived on the scene.
