Mention at least 8 things that happened during the computer pre-history period mentioned in class. Explain why they are considered important enough to be in such timeline.

Avacus: First device use by the man for counting. It was made in China. It is important because it was the first advance ever in technological devices. Naiper bones: It was used for adding and substracting, it could do it with more complex numbers. It was important because it was usefull at that time because people did not have much mathematical knowledge. Pascaline calculator: Used to add and substract. It was a system like the one in cars to count the kilometers it has travelled. Binary system: It was the system used for the first calculator, it could add, substract, multiply and divide, and it is important because it is the same system we use in modern computers. Analytical machine: Design to solve specific problems. Sensus machine: It was the first machine used to make the sensus. It was created by IBM Difference machine: Algebraic equationss, add, substract, multiply, divide square roots, powers. It is important because nowadays we use this kind of problems a lot. Punched cards: Used in old computers to record information

All these devices were and are important because they all helped to create a new one that would be better, also they had a lot of impact when they were created because before people didn't know how to make such complex maths processes, so it simplified people's lives, and also gave ideas to create more devices and machine that also were improved. these devices and machine had a lot of impact and helped to make these kind of machines easier to use, because before they were huge and they started to make them smaller, and more useful as they improve them. Also they are important because in order to advance we need to know the basis which, in this case, are this kind of devices that some we still use them like the binary system or difference machine. So, in order to know ho we are so technologically advanced, we need to study how it was improving all along.
