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

Computers have been modified a several times. They have come a long way since Charles Babbage invented his Difference Engine. His early computers could only make complicated calculations and print the results. But the computers that we have today are able to do much more than that. Today we use computers to play games‚ watch movies‚ listen

multiplied by successive adding and shifting (Guides 45). Perhaps the first actual computer was made by Charles Babbage. He explains himself rather well with the following quote: "One evening I was sitting in the rooms of the Analytical Society at Cambridge with a table full of logarithms lying open before me. Another member coming into the room‚ and seeing me half asleep called out‚ Well Babbage‚ what are you dreaming about?’‚ to which I replied‚ I am thinking that all these tables might be calculated

everything possible‚ pushed Ada night and day‚ to learn mathematics. Even though Ada’s fond interests were elsewhere‚ her mother diminished those interests until Ada grew a fondness of math‚ by no choice of her own. At an early age Ada met with Charles Babbage in London‚ and with that Ada first learned of the Difference Engine. This is when Ada Lovelace’s eyes grew with enormous content‚ interest‚ and enthusiasm of the invention‚ which was later known as the Analytical Engine. In her twenties‚ Ada married

When you think of the people that most influenced your life today‚ Ada Lovelace is almost certainly not a name that pops into mind. But her effect on the modern world cannot be denied. Every time that you send an email‚ listen to Spotify‚ or go on Instagram‚ you are experiencing the long lasting effect of Ada Lovelace on the world today. Because of her work in computer programming‚ civil rights‚ and mathematics‚ she is the most influential person in history. Ada Lovelace’s life was filled

INTRODUCTION : • Who invented the computer? • What is computer? • How did the computer evolve? • Where did it start? Charles Babbage‚ a British professor mathematics is the man who invented the first computer in 1837. It was basically an mechanical type of calculator that also had a memory. The computer was powered by steam engine and used punched cards for programming. A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical

The first mechanical or automatic computer was made in 1822 by Charles Babbage. It was capable of computing several sets of numbers and making had copies of the results. Despite its only single purpose‚ it was the start and the foundation of all the technology we have today. Ever since the day the computer was first made‚ different inventors have been creating their own computers with different functions‚ they also improved the inventions of others. For almost two centuries‚ computers have always

Advantages and disadvantages of computer Advantages of computer:- When Charles Babbage invented the computer decades ago‚ he would probably not have realized the impact it would have on mankind’s future. The importance of computers in today’s world can hardly be over-emphasized. Computers have become so much an integral part of the modern age that we also call this period as the computer age. In the initial years‚ the computer was a huge and complex machine that was used for difficult work like
