HISTORY OF COMPUTERS The abacus was an early aid for mathematical computations. Its only value is that it aids the memory of the human performing the calculation. A skilled abacus operator can work on addition and subtraction problems at the speed of a person equipped with a hand calculator. The abacus is often wrongly attributed to China. In fact‚ the oldest surviving abacus was used in 300 B.C. by the Babylonians. The abacus is still in use today‚ principally in the far east. A modern abacus

A computer is not an acronym and is sometimes abbreviated as comp or ’puter. The term "computer" was originally given to humans who performed numerical calculations using mechanical calculators such as the abacus and slide rule. The term was later given to a mechanical device as they began replacing the human computers. Today’s computers are electronic devices that accept data (input)‚ process that data‚ produces output‚ and then store (storage) the results. The first computer was called the ENIAC

Before computers there were not telephone answering machines‚ handheld calculators‚ fax machines‚ personal computers. People did what they had to do without these things. People wrote letter by hand or with a typewriter‚ they also kept track of data and numbers in ledgers. They were not texting each other‚ there was either in person or over the phone. . Computers are integral to our daily lives and there are millions used daily. Computers are used at home‚ work‚ and school. They are also embedded

Function of digital computer A typical digital computer system has four basic functional elements: (1) input-output equipment. (2) main memory. (3) control unit. (4) arithmetic-logic unit. Any of a number of devices is used to enter data and program instructions into a computer and to gain access to the results of the processing operation. Common input devices include keyboards and optical scanners; output devices include printers and cathode-ray tube and liquid-crystal display monitors

It is difficult to value the role of scientific invention of the second half of XX century. But we shouldn’t forget that it is would have been impossible without countless ideas and inventions which mankind had made before. Every minute of our life is history in the making. Nowadays technical progress is developing so fast‚ that people who lived 50 years ago even couldn’t imagine our modern way of life. They couldn’t realize things‚ which is widespread and habitual for us. Today’s events can soon

The computer was born not for entertainment or email but out of a need to solve a serious number-crunching crisis. By 1880 the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results. The government sought a faster way to get the job done‚ giving rise to punch-card based computers that took up entire rooms. Today‚ we carry more computing power on our smartphones than was available in these early models. The following brief history of computing is

HISTORY OF COMPUTERS Ancient era Suanpan (the number represented on this abacus is 6‚302‚715‚408) 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. Later record keeping aids throughout the Fertile Crescent included calculi (clay spheres‚ cones‚ etc.) which represented counts of items‚ probably livestock or grains‚ sealed in hollow unbaked clay containers.[1][2]
