The History of ComputersWhether you know it or non you suppose on computers for al nigh everything you do in innovational day life. From the second you give-up the ghost up in the morning tothe second you go to sleep computer are tied into what you do and delectation in someway. It is tied in to you life in the most obvious and obscure ways. Take forexample you wake up in the morning usually to a digital alarm clock. You startyou automobile it uses computers the second you turn the key (General Motors is thelargest buyers of computer components in the world). You pick up the phone ituses computers. No mater how hard you try you can get away from them you cant.It is inevitable.Many people think of computers as a current invention, and in reality it isvery old. It is about 2000 years old .1 The depression computer was the abacus. Thisinvention was constructed of wood, devil wires, and beads. It was a wooden rackwith the two wires strung across it horizontally and the beads w ere strungacross the wires. This was use for normal arithmetical uses. These type ofcomputers are considered line of latitude computers. Another analog computer was thecircular slide rule. This was invented in 1621 by William Oughtred who was anEnglish mathematician. This slid principle was a mechanical device made of two rules,one skid inside the other, and marked with many number scales. This slideruler could do such calculations as division, multiplication, roots, andlogarithms.Soon after came some more innovative computers. In 1642 came BlaisePascals computer, the Pascaline. It was considered to be the world-class automaticcalculator. It consisted of gears and interlocking cogs. It was so that youentered the be with dials. It was originally made for his father, a taxcollector.2 Then he went on to build 50 more of these Pascalines, but clerkswould not uses them.3 They did this in tending that they would loose their jobs.4Soon after there were many similar inventions. at th at place was the Leibnizwheel that was invented by Gottfried Leibniz. It got its name because of the wayit was designed with a piston chamber with stepped teeth. 5 This did the samefunctions of the other computers of its time.Computers, such as the Leibniz wheel and the Pascaline, were not usedwidely until the invention made by Thomas of Colmar (A.K.A Charles XavierThomas).6 It was the first successful mechanical calculator that could do allthe normal arithmetic functions. This type of calculator was improved by many
