Computers are all around us and can be considered a wonder of the world. Thanks to the computers, we drive computerized cars, receive letters sent by computers, astronauts can go to the space and return safely. Thus, the computer has significantly changed our world through advances in science and medicine, business and education. In fact the computer is a wonderful electronic brain that we have come to rely on.
First off, computers have contributed to the advances in science and medicine. In the sixties the U. S landed men on the moon because of computers. For example remember the first men that walk in the moon surface Neil Armstrong. We couldn't have gotten there without computers in the equipment and guiding systems. Also doctors use computers to treat patients. For example CAT scans and MRI's find diseases such as brain tumors. So computers are making it easier for doctors to tell us what's wrong with our health.
Computers have been around for quite some time and were developed over many years with contributions from philosophers, inventors, engineers, mathematicians, physicists, technicians, visionaries, and scholars. The first computers were calculating machines and over time evolved into the digital computers as we know them today. It has taken over 180 years for the computer to develop from an idea in Charles Babbage head into an actual computer developed today by many different companies. Therefore, it was a long and tedious path in order to make the computer into what we now use today.
Before computers, people had to do calculations using such tools as a Chinese abacus or a slide rule to work out problems by hand. One day in 1821, Charles Babbage decided that he didn feel like working out tedious mathematics problems anymore and wanted to compute numbers using what he called a machine with steam(Palfreman and Swade 16). For the next ten or so years Babbage worked on designing the Difference Engine, however it was never built as it would have...
