Sir William Thomson 's third tide-predicting machine design, —81 In the first half of the 20th century, analog computers were considered by many Computer hardware engineer research paper be the future of computing.
These devices used the continuously changeable aspects of physical phenomena such as electricalmechanicalor hydraulic quantities to model the problem being solved, in contrast to digital computers that represented varying quantities symbolically, as their numerical values change. As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence, as they can with Turing machines.
It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location and was of great utility to navigation in shallow waters. His device was the foundation for further developments in analog computing.
He explored the possible construction of such calculators, but was stymied by the limited output torque of the ball-and-disk integrators. The lever just in front of the bomb aimer's fingertips sets the altitude, the wheels near his knuckles set the wind and airspeed.
An important advance in analog computing was the development of the first fire-control systems for long range ship gunlaying. When gunnery ranges increased dramatically in the late 19th century it was no longer a simple matter of calculating the proper aim point, given the flight times of the shells.
Various spotters on board the ship would relay distance measures and observations to a central plotting station. There the fire direction teams fed in the location, speed and direction of the ship and its target, as well as various adjustments for Coriolis effectweather effects on the air, and other adjustments; the computer would then output a firing solution, which would be fed to the turrets for laying.
InBritish engineer Arthur Pollen developed the first electrically powered mechanical analogue computer called at the time the Argo Clock. Mechanical devices were also used to aid the accuracy of aerial bombing.

Drift Sight was the first such aid, developed by Harry Wimperis in for the Royal Naval Air Service ; it measured the wind speed from the air, and used that measurement to calculate the wind's effects on the trajectory of the bombs.
The art of mechanical analog computing reached its zenith with the differential analyzer built by H. A dozen of these devices were built before their obsolescence became obvious; the most powerful was constructed at the University of Pennsylvania 's Moore School of Electrical Engineeringwhere the ENIAC was built.
Advent of the digital computer[ edit ] The principle of the modern computer was first described by computer scientist Alan Turingwho set out the idea in his seminal paper,  On Computable Numbers. He proved that some such machine would be capable of performing any conceivable mathematical computation if it were representable as an algorithm.
He went on to prove that there was no solution to the Entscheidungsproblem by first showing that the halting problem for Turing machines is undecidable: He also introduced the notion of a 'Universal Machine' now known as a Universal Turing machinewith the idea that such a machine could perform the tasks of any other machine, or in other words, it is provably capable of computing anything that is computable by executing a program stored on tape, allowing the machine to be programmable.
Von Neumann acknowledged that the central concept of the modern computer was due to this paper. Except for the limitations imposed by their finite memory stores, modern computers are said to be Turing-completewhich is to say, they have algorithm execution capability equivalent to a universal Turing machine.
Electromechanical computers[ edit ] The era of modern computing began with a flurry of development before and during World War II.
Most digital computers built in this period were electromechanical — electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes.Arya Vysya Matrimony.

Computer hardware engineers usually work in research laboratories that build and test various types of computer models.
Most work in high-tech manufacturing firms. Some work in computer systems design firms, research and development firms, or for the federal government/5().
