A computer is compared to a calculator; Used to increase the speed and accuracy of numerical calculations, the abacus and more modern mechanical calculators (dating back more than 5,000 years), use rows of sliding beads or mechanical rods and gears to perform arithmetic operations. However, even during the 19th century calculators were used very often for calculation, but they were not considered computers.
A computer is defined as a mechanical or electronic device that can efficiently store, retrieve, and manipulate large amounts of information at high speeds and with extreme precision. In addition, computers are designed to perform and execute tasks, while adapting to intermediate results without human intervention. This is accomplished through the computer using a list of instructions called a program.
History: computing and technology
An Englishman named Charles Babbage designed and helped build an absolute computer in the mid-1800s. This machine, the analytical engine, was made up of hundreds of mechanical shafts and gears. In the end, this design was obtuse for classifying and processing 40-digit numbers. Also, due to Babbage’s engineering company, Ada Agusta Byron, the daughter of a Lord Byron of that time, took the kidneys and exploited this invention. In connection, a primary program was named Ada. Also, unfortunately for Babbage’s work, the project was complete as it was deemed detrimentally complex for the technology of the day. Thereafter, computers were put on hold for a while.
Seventy years after the death of Charles Babbage, computers became important to certain professors and scholars in the early 20th century. In fact, two teachers from Iowa State University, John Atansoff and Clifford Berry, along with Howard Aiken from Harvard University became interested in completing computer projects. However, his ideal success was not quite certain. Labeled as intermediate results, the Atansoff-Berry project really worked, requiring multiple interventions by the operator while in use. And Aikens’ Mark I just didn’t act independently.
VACUUM TUBES AND TRANSISTORS
Vacuum tubes – ENIAC: Electronic numerical integrator and computer
Furthermore, a few years later, led by the infamous J. Presper Eckert and John Mauchly – from the University of Pennsylvania – they accomplished the developments of the fully functional electronic computer (the ENIAC). The ENIAC became a great attribute regardless of its enormous appearance; 80 feet long; 8 feet wide; 33 tons of weight; made up of 17,000 vacuum tubes that were included in their circuit, they consumed 175,000 watts of electricity, while running calculations of 5,000 additions per second. The vacuum tube intervention then lasted for a solid decade, as the great kings of computing, IBM and Remington, embraced the concept; Acquire a mandated climate controlled environment achieved by large corporations, university systems, and primary government agencies.
Transistors
The taxable excitation of the vacuum tube began to dissipate after the impressive details of the transistor appeared during the 1950s. Although the race with the vacuum tube was a beneficial success, due to its reliability and contributions to computer speed , the transistor took its place on the award shelf. Transistors, for the most part, were the turning point in 20th century computer technology: small and energy efficient. Nobel Prize winners William Shockley, John Bardeen, and alter Brattain influence the design and development of the transistor that resulted in an ideal that was embraced by Bell Labs in the late 1940s. Ultimately, transistors are commonly packaged in compact cabinets housed to further the idea and development of successful integrated circuits; which were common in minicomputers and integrated into the much larger mainframe.
