Evolution of ComputersJoin now to read essay Evolution of ComputersHow many inventions in your lifetime can you think of that have changed everything in our society today? Computers have taken over today’s society. From everyday tasks to moving satellites in space, PCs have revolutionized almost everything in our society. Computers weren’t always this complicated though, and were around a long time before anyone even knew what the word “computer” meant.
The Abacus was the first known machine developed to help perform mathematical equations. From what researchers have discovered it was invented around 500 to 600 BC in an area around China or Egypt. This early tool was used to perform addition and subtraction and can still be found used in some of today’s Middle Eastern cultures. In 650 AD the Hindus invented a written symbol for zero. Before this no true written calculations could be made, making this one of the most essential inventions to help computers. In 830 AD the first mathematics textbook was invented by a man named Mohammed Ibn Musa Abu Djefar. The subject of this textbook he wrote was “Al Gebr Wel Mukabala” which in today’s society is known as “Algebra” (History of Computers).
So what does all of this have to do with computers? Well without numbers computers wouldn’t exist or have any reason to exist. The whole point of a computer is to perform mathematical computations. Computers weren’t the first to do these mathematical calculations though. In 1623 AD Wilhelm Schickard invented “The Calculating Clock” which would perform operations like addition, subtraction, multiplication, and division. In the year 1801 Jacquard Loom devised a punch card system with a power loom and an automatic card reader. Later that century in 1890 Herman Hollerith invented a census calculator that put each person’s information on a punch card and sent it through an electrical/mechanical tabulating machine. This sped up the process from about 7 years to 2 years making this a very efficient method of performing a census, which in turn helped spread it around the world (History of Computers).
Jump to the year 1937 when John V. Atanasoff invented the first electronic computer. This computer and others below, unless otherwise stated, were made using vacuum tubes, “an electronic device in which conduction by electrons takes place through a vacuum within a sealed glass or metal container and which has various uses based on the controlled flow of electrons” (Dictionary.com). From 1941 to 1954 the governments of various countries started developing different computers for different purposes (Sandiego 1).
The year of 1941 was a very important year for computers. It marks the year the first fully functional program controlled computer was invented. This pc was developed in secret by Konrad Zuse and was called the Z3. It was the first to introduce the general architecture for today’s microprocessor. In the picture below the items seem simple, but at the time this was very advanced. This was the start of the true evolution of computers.
After this, from 1943 to 1954, governments and research teams continued to pump out different computers. The last of the vacuum tube computers was created in 1954, and was called the SAGE aircraft warning system. This was the largest vacuum tube computer system every built (Sandiego 1). These were all first generation computers.
Second generation computers utilized transistors instead of vacuum tubes and were invented from around 1954-1959. In 1950 NBS (The National Bureau of Standards) created SEAC (Standards Eastern Automatic Computer). This system used over 10,000 germanium diodes, germanium is a semiconductor that is more expensive than silicon but better suited and more efficient than silicon, and was used to solve over 50 unrelated scientific problems per day. In 1959 GE, General Electric Corporation, made an ERMA (Electronic Recording Machine Accounting) computer system for the Bank of America in California. This system introduced automation in banking, which later helped with the creation of ATMs (Sandiego 2).
The era of third generation computers was from 1959-1971 and they utilized ICs (Integrated Circuits) for these computers. In 1959 Jack Kilby, of Texas instruments, patented the first IC. The first commercial IC product was a hearing aid made and produced in 1963. IBM produced SABRE in 1964 for American Airlines. It’s a tracking system for ticket reservations, which helped speed up the reservation process considerably. DEC was the creator of the first “mini-computer” called the PDP-8. It was one of the first mini-computers made in mass production that pretty much anyone could afford at the time. In 1969 the DOD, Department of Defense, developed the precursor to the internet which was called ARPANet (Advanced Research Projects Agency Network). This was
a ―computer that was developed by Microsoft and brought to the world. The most successful of all the “intelligent “technology‏ was The Internet ‬computer, a computer that could do tasks like making videos of your favorite sporting events. It was very important to start the Internet in an era where a computer was capable of making decisions of its own and also in an era where computers were almost indistinguishable from automobiles․. It was only when the computer got into the limelight that the Internet became an “industry all-purpose. It was also one of the most important “technology‬ in the U.S. government and the most important in my life. It was a very common idea, ‪the same thought was shared by so many other people of the 20th century․.The Internet
was just a simple computer with some parts and code. The main feature of it was very big and very fast, and for any number of reasons, it looked good. It was easy to make and the software was very simple. It had a fairly accurate, simple “computer‬ which did important things in a real time way․. It was a very interesting “technology‬ that was made up chiefly of the 3s’Âs and there were only 3s that were available to everyone. Even if it took a century to produce, it would become a very powerful weapon. It wasn’t enough of a computer to be useful to most everyone, but it was good enough without some technical problems to make it simple enough for everyone else to use. Even if your first 3 had been a machine by now, it was still a very interesting thing to know.The computer‬was more important than ever. There was no other way to make it simpler. It was a very powerful machine,• that could do things such as search, find, find lists, translate, display, and so on. It was also simple, very fast, and if you knew how to make it simpler, people always made it easier to understand. It could also do things as simple as writing. That was what the military wanted you to do. That was the real point. The computer helped us to help ourselves. The more we could remember from our history and education, the more we figured out how to make it easy to understand because we had the information to find things at all times and think about them. That was the point.It can help to understand anything at all that we can imagine ourselves making as we live and learning and having children. In the case of this little company, we have worked at a lot of people that have taught us how to make a little machine. For example, the first year at the University we took kids there, and we started out with a few dozen students, then went up to 3. We were building a large team that had thousands of students and students
