Summary
computer has been around for a few years, some parents you probably around 1951 when the first computer was purchased by a company's business. the computer has changed so fast many people cannot follow the change. These changes are happening so fast that a lot of people don't know how modern computers which we have started.
Since ancient times, people have ways to deal with data and numbers. early people tied knots in ropes and carved marks on clay tablets to track livestock and trade. Some consider the 5,000 years-old abacus frame with beads strung on the wire became the first true computing assistance. In the mid-1600s, Blaise Pascal, and his father, a tax officer himself, work on the tax to the Government of France in Paris. The two spent hours searching and refiguring the taxes that every citizen. Young Blaise decided in 1642 to build engines that add and subtraction can aide in the process as tedious and time consuming.
in honor, there is a computer language called Pascal.
The next big step for the computer arrived in 1830 's when Charles Babbage decided to build a machine to help her finish and print mathematical tables. Babbage was a mathematician who taught at the University of Cambridge in the United Kingdom. He began planning a Totalizer machine call it analysis. The idea for this machine is incredible as is the computer we know today. It is for reading programs from punched cards, pictures and save the answers to different problems, and print your answers on paper.
the next big Step for computers came when Herman Hollerith entered the contest given by the United States Census Bureau. This is a contest to see who could build a machine that would calculate and record the information faster. Hollerith, a young man who works for the Bureau built a machine called the tabulator machine that read and sorted data from punched cards. Tabulator read punched cards they pass a small brush. Each time the brush found a hole, it's a complete electric circuit. This special count due to fast to improve data for that answer.
Thanks to Hollerith's machine, instead of taking seven and half years to count census information only took three years, even with the 13 million more people since the last census. Pleased with his success, Hollerith forms tabulating machine company in 1896. The company was sold in 1911. And in 1912 the company became International Business Machines Corporation, better known now as IBM.
What is considered the first computer created in 1944 by the Harvard Professor Howard Aiken. Mark I computer is very similar to the design of Charles Babbage had mechanical parts, but with a few electronic parts. This machine is designed to be programmed to do a lot of computer work. This flour machine is what we now know as a PC or personal computers. Mark I was the first computer was funded by IBM and about 50 feet long and 8 feet tall. It used mechanical switches to open and close the electrical circuit. It contains more than 500 miles of wire and parts of 750,000.
kind of more modern computer begins with John von Neumann development software written in binary code. It was von Neumann who started the practice of storing data and instructions in binary code and memory usage to store data, as well as the program starts. A computer called the EDVAC (Electronic Discrete Variable computer) is built using the binary code in the 1950s. Before EDVAC, computers such as the ENIAC could do a job then they have to be rewired to perform different tasks or programs. EDVAC concept store different programs on punched cards instead of rewiring a computer that led to the computer we know today.
While modern computers is far better and faster than time, EDVAC computers today will be impossible with the knowledge and the work of many great inventors and pioneers.
