A Brief History of Computer Science

Over the past 60 years, computers have been transitioning from room size supercomputers to desktops and laptops, and to our pockets. However, the true history of machine-assisted human computing ("computer" originally meant people, not machines) can go further back. This week is the Computer Science Education Week, celebrating the World Science Festival to celebrate the long history of humanity and the long history of computers.

The first one in history was abacus, which helped ancient technicians gain the benefits of counterparties, but the counterparties still calculated cattle and amphora by hand. The oldest known complex computing device known as the Antikythera mechanism dates back to 87 BC; Greeks were discovered in the Aegean shipwreck in the early 20 th century, but this Gear Equipment It is speculated that I used it. Until 2006, the importance of helping to calculate astronomical positions and helping them navigate the sea was not recognized. In 1843, when British mathematicians Ada Lovelace and Charles Babbage co - authored the first programmable computer theory, the computer again jumped. However, the modern computer age started with a transistor devised by Allen Turing's Turing machine concept and scientists of three Bell laboratories, enabled modern calculations and received the 1956 Nobel Prize in Physics. did. For decades, computing technology has been dedicated to the government and the military; after that, the academic institution has come on line, Steve Wozniak added a board for Apple-1 to make home computing practical I made. On the connection side, Tim Berners-Lee created the World Wide Web and Marc Andreessen built the browser. This is how our glasses live in a world that tells us what we are seeing. With wearable computers, embedded chips, smart appliances and other advancements and future developments, a journey to build smarter, faster, and more powerful computers has just begun

Of course, some of the confusion comes from history. APComputer Science A (and former AP CS AB) is the only program in the city for decades and is a programming course called Computer Science. The AP Computer Science Principles course is a broad base that is the foundation of more general "computer science". The new AP Computer Science Principles course starts at the end of 2014 and begins in the 2016-17 academic year, and in 2014, 60 million students participate in the "time code" for 20 million in 2013 did. We currently have 27 states that recognize computer science courses as more than elective subjects, and the adoption rate is improving.

The history of computer science began long before the field of modern computer science. The development of the last few centuries refers to what we call now computer science. This development from mechanical inventions and mathematical theories into the concepts and machines of modern computers has brought the development of major academic disciplines and the foundation of a worldwide large-scale industry. The earliest tool used for calculations was abacus. It was developed in Sumer between 2700 BC and 2300 BC. Sumer's abacus consists of a series of consecutive columns that define the number of consecutive digits in hexadecimal 11. The original use is a line drawn with sand and pebble. Modern design of abacus is still used as a calculation tool like Chinese abacus like that

As it is very prominent in society, I will present a brief history of computers. The 20th century is an era of invention and innovation. More specifically, with the development of electric power, computer technology has made remarkable progress. The invention of computers arises from the dependence on machine equipment that depends on machine equipment. - One of the most important aspects of studying the history of places is the reason this site first appeared. FBI's Regional Computer Forensics Lab may be an organization that is not generally well-known, but it plays an important role in our judicial system and our daily lives.
