Ex1+T5+Question+3

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.

Everything starts with the abacus, it is really important because it is the start of the machines that helped the human being with their calculations. After the abacus we have an artifact called napier´s bones, which is less slow, easier and a little more sofisticated abacus, it is made of bones and his inventor is Napier that is why it is called like that, there for it was the sodoku. The calculations were still slow even by using this artifacts, that is why a man called Pascal made the pascaline calculator, from there its name, this one is the first calculation ever made, although it was really big and slow, this invention managed to succesfully calculate things in fact the only thing it can made with nubres was adding and substracting. After this they start making some other machines that are the ancestors of the computers and they used a language called binary system, this system consists of 0's an 1's, that is how the computers work, so they can understand words, phrases, images, etc by only reading with zeros and ones. There is also something called punched cards that are papers with absence or precence of holes, this is also a way of trasmiting information. this is a very important device becuase although its really ancient and really big, this was one of the fist ways compiters started to undertand commands. man called Charles Babbage, is the creator of the difference machine, but this was a failure, it didn´t worked out. After his differential machine he did the analytical machine, this one was not a failure. the memory of ancient coputers ocupe many sapce, in fact a coputer can ocupe 4 flors of a bulding because the memory sticks only ocupe two bianre numbers, so a simple word as "apple" can ocupe more than 4 memory sticks. Finally we have the census tabulator that was made by IBM, one of the greatest companies of computers. An interesting thing about the computers history is that the first programer was a woman called Ada which was the wife of a greeat computer programes, well she managed to be not only a great programer but also greater than her husband, and being a woman in those days, that was a really hard task to manage. Computers have evolved since long time ago, nowadays we have a very advanced technology and the most sofisticated computers, they are considered important because they facilitate the human's life, now it is faster and not so complicated to find info about something, in comparisson before you have to spent hours in the library and read tons of books not to mention computers were HUGE! and didnt even fufill the facilities a smal l computers brings to you nowadays.
