History of information systems

Data storage device Early electronic computers such as Colossus made use of punched tapea long strip of paper on which data was represented by a series of holes, a technology now obsolete. The earliest form of non-volatile computer storage was the magnetic druminvented in [16] and used in the Ferranti Mark 1the world's first commercially available general-purpose electronic computer. It has been estimated that the worldwide capacity to store information on electronic devices grew from less than 3 exabytes in to exabytes in[21] doubling roughly every 3 years.

The Ishango bone Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers.

The earliest counting device was probably a form of tally stick.

May 09,  · The story of how data became big starts many years before the current buzz around big data. Already seventy years ago we encounter the first attempts to . A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer monstermanfilm.com computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an . Pre-Social Security Period. Traditional Sources of Economic Security. All peoples throughout all of human history have faced the uncertainties brought on by .

Later record keeping aids throughout the Fertile Crescent included calculi clay spheres, cones, etc. The Roman abacus was developed from devices used in Babylonia as early as BC.

Since then, many other forms of reckoning boards or tables have been invented. In a medieval European counting housea checkered cloth would be placed on a table, and markers moved around on it according to certain rules, as an aid to calculating sums of money.

The ancient Greek -designed Antikythera mechanismdating between and BC, is the world's oldest analog computer.

The Antikythera mechanism is believed to be the earliest mechanical analog "computer", according to Derek J.

It was discovered in in the Antikythera wreck off the Greek island of Antikytherabetween Kythera and Creteand has been dated to c. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later. Many mechanical aids to calculation and measurement were constructed for astronomical and navigation use.

A combination of the planisphere and dioptrathe astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy. An astrolabe incorporating a mechanical calendar computer [9] [10] and gear -wheels was invented by Abi Bakr of IsfahanPersia in The sectora calculating instrument used for solving problems in proportion, trigonometry, multiplication and division, and for various functions, such as squares and cube roots, was developed in the late 16th century and found application in gunnery, surveying and navigation.

The planimeter was a manual instrument to calculate the area of a closed figure by tracing over it with a mechanical linkage. A slide rule The slide rule was invented around —, shortly after the publication of the concept of the logarithm. It is a hand-operated analog computer for doing multiplication and division.

As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions.

Slide rules with special scales are still used for quick performance of routine calculations, such as the E6B circular slide rule used for time and distance calculations on light aircraft. In the s, Pierre Jaquet-Droza Swiss watchmakerbuilt a mechanical doll automaton that could write holding a quill pen.

By switching the number and order of its internal wheels different letters, and hence different messages, could be produced. In effect, it could be mechanically "programmed" to read instructions. It used a system of pulleys and wires to automatically calculate predicted tide levels for a set period at a particular location.

The differential analysera mechanical analog computer designed to solve differential equations by integrationused wheel-and-disc mechanisms to perform the integration. InLord Kelvin had already discussed the possible construction of such calculators, but he had been stymied by the limited output torque of the ball-and-disk integrators.

The torque amplifier was the advance that allowed these machines to work. Starting in the s, Vannevar Bush and others developed mechanical differential analyzers. First computing device A portion of Babbage's Difference engine.

Charles Babbagean English mechanical engineer and polymathoriginated the concept of a programmable computer. Considered the " father of the computer ", [17] he conceptualized and invented the first mechanical computer in the early 19th century.

After working on his revolutionary difference enginedesigned to aid in navigational calculations, in he realized that a much more general design, an Analytical Enginewas possible. The input of programs and data was to be provided to the machine via punched cardsa method being used at the time to direct mechanical looms such as the Jacquard loom.

For output, the machine would have a printer, a curve plotter and a bell.Information Systems is an academic study of systems with a specific reference to information and the complementary networks of hardware and software that people and organizations use to collect, Sage, S.M.
