Computer users of today probably think computers have been developed within the 20th century. Surprisingly, computers originated before the birth of Jesus Christ. Computers are an essential part of each and every day in our modern life. They entertain, educate, assist in daily tasks and in many instances, fascinate us with their capabilities. They can be found almost everywhere. Computers are the basis for PDA’s, which are used by many busy people to schedule their work and life appointments; air traffic control systems, that direct airplanes in their movement; satellites, that keep us in communication with the rest of the world; information systems which aid manufacturing, and in the systems which aid in health care. Computer technology has made rapid advances within the last seventy-five years. Let’s examine the development of computers throughout history.
A computer is a machine that performs rational calculations. A “computer” may be able to process information to perform repetitive tasks, as well as store information. Computers can be as simple as pebbles, systematically placed on stones, to as complex as massive machines, processing and storing large amounts of data. Computers may require many operators or operate

Also during the period of the 1960’s, computer producers started to offer additional capabilities, with more accessories, at a wider range of prices. Some of the accessories included: consoles, card feeders, printers, cathode–ray–tube displays, and graphing devices. It was utilized throughout World War II. Let us recognize them for what they are and utilize them for the betterment of mankind. Productivity in programming has not advanced very rapidly, making software a major expense of large systems. A major step to the common computer screen occurred on August 27, 1940, when the first TV show in color was seen. In 1951, the Universal Automatic Computer, UNIVAC I, was produced by the Remington Rand Corporation. These “bones” were movable multiplication tables, aiding with multiplication and division. Atanasoff, designed a model of the ABC (Atanasoff-Berry Computer), in conjunction with a graduate student named Clifford Berry. It was advertised to be able to add a column of ten-digit numbers taller than the Statue of Liberty in approximately one second. In 1943 at Harvard University, Grace Murry Hopper and Howard Aiken work on the Harvard Mark I. In all essence, this was the first computer. This garage allowed them to make audio oscillators and many other electronic devices, which were the forerunners of today’s computer components.
