History and development of computers essay

Whether the effect is negative or positive, computers control nearly every aspect of our everyday life. Computers History and development of computers essay evolved from bearing the role of strictly computing to having the ability of completing unthinkable tasks.

Supermarket scanners calculate our grocery bill while keeping store inventory; computerized telephone switching centers play traffic cop to millions of calls and keep lines of communication untangled; and automatic teller machines ATM let us conduct banking transactions form virtually anywhere in the world.

The History and Evolution of Cell Phones

All of this amazing technology started over five thousand years ago and continues to grow with an unknown culmination. Around five thousand years ago in Asia minor, a simple machine bearing a system of sliding beads arranged on a rack such as ones found in a pool hall may be considered the first computer.

It is known as the Abacus and is still in use today.

Merchants used the Abacus to record their barter transactions. Its popularity began to fall when the use of paper and pencil spread particularly throughout Europe, its importance diminished. The next significant advance of computing started with a man named Blaise Pascal, nearly twelve centuries ensuing the invention of the Abacus.

Pascal was an eighteen year-old son of a French tax collector in the early seventeenth century. To ameliorate his father?

For example, as one dial passed nine, the next dial turned to represent one in the tens column as the original dial returned back to zero.

History of Computers Introduction: The electronic computer has now been used commercially for less than 25 years. It grew out of a search lasting centuries for a more accurate, faster way to perform calculations. Primitive and ancient man used his fingers, shells, beads, sticks, and other o. History of Computers: From Abacus to Smart-phones Aim: In this lesson, you will learn: Various devices that have been used for computations in the past. Major milestones in development of modern day computers Development of Internet, browser and other Internet based applications, games and Linux. i. The first step for gathering information is. Free Essay: DEVELOPMENT OF COMPUTERS As we are stepping towards the era of , man have consistently been innovative and creative in developing and.

A German mathematician and philosopher named Gottfried Wilhem von Leibniz improved the Pascaline in by inventing a machine with the ability to not only add, but multiply as well.

The refined model used a stepped-drum gear design rather than Pascal? Charles Xavier Thomas de Colmar was another great inventor whose efforts assisted in the evolution of the simple computer. Colmar was a Frenchman whom invented a machine with the ability to perform the four basic arithmetic functions, he invented the Arithometer, which offered a more practical approach to computing offering the ability to add, subtract, divide, and multiply.

The enhanced versatility of the arithometer influenced its popularity up until World War I. With the help of his predecessors, Pascal and Leibniz, Colmar helped define the age of mechanical computation. A British mathematics professor by the name of Charles Babbage began the understanding of our present day computer.

It is said that the automation of computers began with one simple quote,? I wish to God these calculations had been performed by steam!?

Babbage believed there existed a strong affinity between machines and mathematics. He reckoned, if machines were best at performing flawless tasks in repetition; while mathematics, often required the unpretentious repetition of steps, he could apply the capabilities of machines to the demands of mathematics to refine the arithometer into a more evolved and elaborate machine.

Babbage named is first attempt a Difference Engine which could be used to perform differential equations in The Difference Engine was powered by steam, the size of a car, and was capable of printing out the results automatically.

Babbage finally called it quits after ten years of hard work.

He was inspired to put is time into the invention of the first general-purpose computer called the Analytical Engine. The Analytical Engine was also never built. It contains over 50, components, including small-perforated cards containing operating instructions as the basic design.

The engine also contained a? His idea of punch cards was borrowed from Joseph-Marie Jacquard who invented the Jacquard Loom obviously named after him. The Loom, produced in used punchboards to control weaving patterns.

Computers were looked at as a way to simplify large workloads into discreet tasks. The United States census of took seven years to tally. The fear of later censuses taking an even more absurd amount of time to count, the bureau turned to technology.

An American inventor named Herman Hollerith also applied the Jacquard loom concept to computing. Rather than use Babbage? Punched holes in the cards would represent letters and number, a single hole depicted a number, while a combination of two holes portrayed a letter.

This contrivance allowed the bureau to enumerate the census results in six weeks.

Not only did Hollerith? After this point in history the evolution of the computer is began to become an increased desired area of interest. The first major interest began with the onset of World War II. The lust of the government having the ability to use computers to assist them in warfare inspired them to increase the funding of computing projects resulting in the motivation for technical progress in computing.

German engineer Konrad Zuse had developed a computer to design airplanes and missiles by called the Z3.The history of computer science began long before our modern discipline of computer science. Developments in previous centuries alluded to the discipline that we now know as computer science.

[1] This progression, from mechanical inventions and mathematical theories towards modern computer concepts and machines, led to the development of a. The history of computers is short but very complicated.
