storage. This is when the first books and libraries are developed between those times. You have probably heard about the Egyptian scrolls which were popular ways to write down information to save. Some groups of people actually binding all the paper together into a book-like form. The first numbering system used is during this period of times. Around 100 A.D. was when the first 1 to 9 system was created by people from the India. However, it was not until 875 A.D. (775 years later) that the number 0 was invented. And now that numbers were created, people wanted stuff to do with them so they created the calculators. A calculator was the very first sign of an information processor known. The popular model of calculator during that time was the abacus. The mechanical age is when we first start to relate the connections between our current technology and its ancestors. The mechanical age can be defined as the time between 1450 A.D. and 1840 A.D. A lot of new technologies are developed as there is a large explosion in interest with this area. Technologies like the slide rule (an analog computer used for multiplying and dividing numbers) were created. Blaise Pascal has invented the Pascaline which was a very popular mechanical computer during that time. Charles Babbage has developed the difference engine which can tabulate polynomial equations using the method of finite differences. There were lots of different machines created during that period of times and while we have not yet gotten to a machine that can do more than one type of calculation in one, like our modern-day calculators, we are still learning on about how all of our all-in-one machines started from the beginning. Also, if you look at the size of the machines invented during that era compared to the power behind them it seems (to us) that it is absolutely ridiculous to understand why anybody would want to use them, but to all the people living in that time, ALL of these inventions were HUGE. Now we are finally getting close to some technologies that resemble our modern-day technology nowadays. The electromechanical age can be defined as the time between 1840 A.D. and 1940 A.D. These are the beginnings of the telecommunication. The telegraph system was created in the early 1800s. Morse code was created by Samuel Morse in the 1835. Th>
