Only once in a lifetime will a new invention come about to touch every aspect of our lives. Such a device that changes the way we work, live, and count is a special one, indeed. A machine that has done tout ensemble this and more now exists in nearly every stemma in the U.S. and one out of every two households (Hall, 156). This dumbfounding invention is the computer. The electronic computer has been around for over a half-century, but its ancestors have been around for 2000 years. However, only in the decease 40 years has it changed the American society. From the first woody abacus to the in style(p) high-speed microprocessor, the computer has changed nearly every aspect of peoples lives for the better.
The earlier existence of the late day computer ancestor is the abacus. These construe back to almost 2000 years ago. It is simply a wooden rack holding parallel cable on which string of beads are strung. When these beads are moved along the wire according to programming rules that the user must memorize, all ordinary arithmetical operations can be performed (Soma, 14). The next innovation in computers took place in 1694 when Blaise Pascal invented the first digital designing machine. It could only add numbers and they had to be entered by bout dials. It was designed to help Pascals father who was a tax gatherer (Soma, 32).
In the early 1800, a mathematics professor named Charles Babbage designed an machinelike calculation machine. It was steam powered and could store up to gram 50-digit numbers. Built into his machine were operations that included everything a modern general-purpose computer would need. It was programmed by and stored data on card with holes punched in them, appropriately called punch cards. His inventions were failures for the most part because of the...
