Ex1+T1+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.

1-Abacus was invented in China, also called the counting frame. 2-Pascaline calculator was invented (Could only substract and add). pascal invented it when he was 19 years old with the purpose to help his father who was a (cobrador), it was the first idea of a machine or a mechanical device that made equations. it worked with wheels that wouls go from 0 to 9. 3-Wilhelm's calculator, that added, multiplied, divided and substracted. (considered as the first one, as it had simmilar functions to a now a days calculator) 4- Jaquards punched cards were invented.they store info by the absence or precense of destinated holes 5-Binary system used for the functioning of machines and its still used now a days 6-Charles Babbage invented the anlitycal machine and the difference machine.the could performs polynomial and simple operations, however, results always varied, menaing eacsh time it ran it would have different results. 7-Lady lovelace invented the first computer program. 8-The census machine was invented.

Reason of why this things were important:

1-it was the beggining of counting (adding or sucstarctin) and really representing counts in for example, a business. Allowed to do mathemical reasoning ( do simple equations), developed mathemical language that was later used for the functioning of machines. 2-Even though this calculator had basic functions, it was the first object that could do equations with a mechanical procces, it could achieve an specific objective with calculations, the same thing now a days computers do it was the first idea of a machine or a mechanical device that made equations. it worked with wheels that wouls go from 0 to 9. 3- It could do complex calculations with a mechanical process, it helped in the development of machinesd to do more complex functions. 4- this were the first tools that could actually store info 5- When binary system was used for the functioning of machines, it appeared to be a good way to function computers as they only read as on-off 6- they were as CD's in our time, they could store information and give the computer orders. 7- important because it meant that it culd really help in having other functions in computers 8- the long process of the census was reduced from 11 years to 5years. the first computer compant appeared.
