Computer History Back in ancient times people used to use there fingers to count. Ten became the basis of number systems for everybody because of 10 fingers and 10 toes. When they ran out of fingers and toes to count on they used stones and scratches in trees to store and record information. Later somebody invented the abacus. The abacus is still in use today in many Asian countries. Some people that use the abacus are as fast as a human now using a calculator. They used the abacus to keep track of totals and as a way to store numbers and not have to remember them. In the 1600's John Napier who was a great mathematician invented a new way to count. Away that was a bit better then the abacus. The thing that he invented was called Napier's Bones. He also invented calculator rods. His machine that he invented could multiply. When you move rods a person could multiply two large numbers in a way. It really only helped assist the people that use it. Also in the 1600's Blaise Pascal !was a mathematician. He invented a shoe box size machine. His shoe box size machine could add quickly and replaced Napier's Bones. His device was mechanically geared. It was the first computer of modern times. Libenz the mathematician invented the Stepped
was a mathematician. He invented a shoe box size machine. His shoe box size machine could add quickly and replaced Napier's Bones. His device was mechanically geared. It was the first computer of modern times. Libenz the mathematician invented the Stepped Reconer. The Stepped Reconer was a very clever machine at the time because it could multiply and divide as well as it could add and subtract large numbers. This device was great at it's time. In the 1800's Joseph Jacquard invented a loom type of machine that used punch cards to store information. A punch card was kind of like a modern day disk. His loom could repeat patterns with different cloths. It was like a computer run Loom. The first calculating machine was invented by Charles Babbage. His machine was the very first modern computer. His computer used the binary number system to calculate. The binary number system is made up of one's and zero's. There are eight one's and zero's for every byte one thousand bytes for a kil! obyte and one thousand kilobits for a megabyte and so on. His computer that he invented was called the Analytical Engine. He didn't have enough money to complete his computer when he started building it so Ada Augusta Lovelace helped fund Charles Babbage. In the 1800's the United States of America was looking for a new way to do a census. As soon as they were done with one it was time for the next census. The machine they needed was a Tabulating Machine invented by Herman Hollerith. Herman Hollerith used his punch card machine and worked for the United States army. In the 1900's Howard Aiken built the first electromagnetic computer. He called this computer the Mark One. The Mark One used punch cards that stored and relayed information. He built his computer for IBM in 1944. In 1946 an all digital computer was built by J. Presper Eckert. His computer that he built called the Eniac weighted over 30 tons and took up a whole gymnasium. The Eniac used vacuum tubes that got hot and ! he new chip was less expensive than older models and performed ten million calculations per second. Over the years computers have progressed
