Whether you know it or not you depend on computers for almost everything you do in modern day life. From the second you get up in the morning to the second you go to sleep computer are tied into what you do and use in some way. It is tied in to your life in the most obvious and
obscure ways. Take for example you wake up in the morning usually to a digital alarm clock. You start you car it uses computers the second you turn the key (General Motors is the largest buyers of computer components in the world). You pick up the phone it uses computers. No matter how hard you try you can get away from them you can't. It is inevitable. Many people think of computers as a new invention, and in reality it is very old. It is about 2000 years old.

The first computer was the abacus. This invention was constructed of wood, two wires, and beads. It was a wooden rack with the two wires strung across it horizontally and the beads were strung across the wires. This was used for normal arithmetic uses. These type of computers are considered analog computers. Another analog computer was the circular slide rule. This was invented in ...
... 1621 by William Oughtred who was an English mathematician. Soon after came some more advanced computers. In 1642 came Blaise Pascal's computer, the Pascaline. It was considered to be the first automatic calculator. It consisted of gears and interlocking cogs. It was so that you entered the numbers with dials. Around 1812 in Cambridge, England, new advancements in computers was made by Charles Babbage. His idea was that long calculations could be done in a series of steps they were repeated over many times.7 Ten years later in 1822 he had a working model and in 1823 he had fabrication of his invention. He had called his invention the Difference Engine. This computer was never finished for many reasons. Some of the reasons were not having precision mechanics and could solve problems not needed to be solved at that time. After Babbage's computer people lost interest in this type of inventions. Eventually inventions afterwards would cause a demand for calculations capability that computers like Babbage's would capable of doing. International Business Machines (IBM) was formed. An invention during this time ,1906, would influence the way that computers were built
in the future, it is the first vacuum, and a paper was wrote by Alan Turing that described a hypothetical digital computer. Around the same time there was a new computer built was more popular. It was more popular because it not only had the ability to do calculations but it could also could do the dissension make power of the human brain. When it was finished in 1950 it
became the fastest computer in the world. From the 1980 on there was a was a large demand for microcomputers Suck as the IBM PC and Apple not only in industry but in the homes of many people. Many other computers appeared during the 80's. Some were the Commodore, Tandy, Atari, and game systems such as the Nintendo and many others. Who knows what's in store for the future or you could say the fifth generation of computers.
