In 1812, Charles Babbage began designing the “Difference Engine,” which is considered one of the first programmable computers (evolutionofcomputers.edublogs.org/). Computers are used in many different fields around the world. As time passed, computers also progressed. Computers were once huge. The myths of the computer taking over power will not be realized. Humans are now able to carry small computers in their pockets. The history of computers The first computer in history is called the “Difference Machine”. The “Difference Machine” was designed to be able to solve complex mathematical equations and remember the answers to solved problems (evolutionofcomputers.edublogs.org/). “Because of the cost of thousands of precision-cut metal gears. Charles Babbage only built a prototype of the machine,” (evolutionofcomputers.edublogs.org/). “Babbage made an improved version of the machine with the help of the Countess of Lovelace. The improved version is called “Analytical Engine”. This machine could operate with prescribed instructions now called program. The machine was given a sheet of paper with holes punched in it, this was the equation. This computer also cost Babbage too much to build. These machines are considered the first computers, because they had a processor, memory and a program,” (http://evolutionofcomputers.edublogs.org/). Babbage may never have mass-produced the machines, but he kicked off the evolution of computers. “John Mauchly and John Presper Eckert developed the ENIAC I (electrical digital integrator and calculator) in the year 1946,” (http://inventors.about.com /). “The ENIAC became the first modern computer. The project was sponsored by the US Army to calculate the artillery… in the center of the card… shows an image that allows doctors to look under the patient's skin. When the scanner passes over the patient, it displays an image of the bone and tissue structure on a computer screen” (http://it-elahi.blogspot.com/). “Education: Computers are used in universities to provide methods of teaching in different ways. Computer science education is very familiar and is rapidly increasing the graph of computer science students. There are numerous methods in which educational institutions can use computers to educate students. There are many computer-based educational software available, which students can learn to read, count or speak a foreign language. Software that combines the excitement of games with real information content is becoming increasingly popular. Some organizations use information technology in employee training programs” (http://it-elahi.blogspot.com/).
