The History of Computer Technology

            Only once in a lifetime will a new invention come about to.



             this and more now exists in nearly every business in the.

             United States. This incredible 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 last 40 years has the computer.

             changed American management to it's greatest extent. From.

             the first wooden abacus to the latest high-speed.

             microprocessor, the computer has changed nearly every.

             aspect of management, and our lives for the better.

             The very earliest existence of the modern day computer's.

             ancestor is the abacus. These date back to almost 2000.

             years ago (Dolotta, 1985). It is simply a wooden rack.

             holding parallel wires on which beads are strung. When.

             these beads are moved along the wire according to.

             programming rules that the user must memorize. All ordinary.

             arithmetic operations can be performed on the abacus. This.

             was one of the first management tools used. .

             The next innovation in computers took place in 1694 when.

             Blaise Pascal invented the first digital calculating machine. It.

             could only add numbers and they had to be entered by.

             turning dials. It was designed to help Pascal's father, who.

             was a tax collector, manage the town's taxes (Beer, 1966).

             In the early 1800s, a mathematics professor named Charles.

             Babbage designed an automatic calculation machine.

             (Dolotta, 1985). It was steam powered and could store up.

             to 1000 50-digit numbers. Built in to his machine were.

             operations that included everything a modern.

             general-purpose computer would need. It was programmed.

             by and stored data on cards with holes punched in them,.

             appropriately called punch cards. This machine was.

             extremely useful to managers that delt with large volumes of.

             good. With Babbage's machine, managers could more easily.

             calculate the large numbers accumulated by inventories. The.

             only problem was that there was only one of these machines.

             built, thus making it difficult for all managers to use (Beer,.
