years. The modern computers we are all familiar with can trace their roots back to simple computational machines that seem far removed from what we think of as a computer today. Simple Computers • By definition‚ a computer is any device capable of performing mathematical equations or calculations. Therefore‚ many simple devices such as an abacus (which dates back to at least 300 BCE) or a slide rule (first made in England in the 1630s) are the forerunners of today’s modern computers. The Calculating

Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable programs. It involves activities such as analysis‚ understanding‚ thinking‚ and generically solving such problems resulting in an algorithm‚ verification of requirements of the algorithm including its correctness and its resource consumption‚ implementation (commonly referred to as coding[1][2]) of the algorithm in a target programming language.
