What is an Information Systems and Types of Information Systems? Information System Assignment

Definition
Your computer is a programmable electronic device designed to recognize data, perform prescribed mathematical and logical operations at high speed, and screen the results of these functions, all under the control of software. Mainframes, desktop and laptop computers, tablets and smartphones are some of the several types of computers. An electronic machine which helps in solving problems quickly and easily. It solves problems regarding to instructions directed at it by the computer end user called programs or software. It is a digital machine(that uses binary digits) used in all field

Automation
Most humans have trouble with math. Showing this, try doing 584 x 3,220 in your head. It really is hard to remember all the steps! People made tools to help them remember where these were in a mathematics problem. The other problem folks have is that they need to do the same problem again and again and over again. A cashier were required to make change every day in her head or with a piece of paper. That got a lot of time and made blunders. So, people made calculators that performed those same things again and again. This part of computer record is named the "history of automated calculation," which is a fancy key phrase for "the annals of machines which make it possible for me to get this done same maths problem over and over without making errors."The abacus, the glide guideline, the astrolabe and the Antikythera system (which dates from about 150-100 BC) are examples of automated computation machines.

Programming
People do not need a machine that would do the same thing over and over again. For example, a music box is a machine that plays the same music over and over again. Some people wanted to be able to tell their machine to do various things. For instance, they wished to notify the music box to experiment with different music every time. They wanted to have the ability to program the music container- to order the music package to play different music. This part of computer background is named the "history of programmable machines" which is a fancy phrase for "The history of machines that I could order to do various things if I learn how to speak their language."One of the first examples of this is built by Hero of Alexandria (c. 10-70 AD). He built a mechanised theatre which performed a play sustained ten minutes and was handled by a intricate system of ropes and drums. These ropes and drums were the terminology of the machine- they told what the machine did so when. Some people claim that is the first programmable machine.Historians disagree on which early machines are "pcs". Many say the "castle clock", an astronomical clock developed by Al-Jazari in 1206, is the first known programmable analog computer. The length of night and day could be adjusted every day in order to account for the changing lengths of day and night over summer and winter. Some count this daily modification as education.Others say the first computer was made by Charles Babbage. Ada Lovelace is known as to be the first programmer.

The Computing Era
By the end of the center Age ranges, people in European countries thought math and anatomist were more important. In 1623, Wilhelm Schickard made a mechanical calculator. Other Europeans made more calculators after him. They were not modern personal computers because they could only add, subtract, and increase- you cannot change what they have to make them take action like play Tetris. As a result of this, we say they were not programmable. Now technicians use computers to design and plan.In 1801, Joseph Marie Jacquard used punched newspaper cards to see his textile loom the type of structure to weave. He could use punch cards in order to the loom how to proceed, and he could change the punch cards, this means he could program the loom to weave the design he wanted. This means the loom was programmable.Charles Babbage wanted to make an identical machine that could analyze. He called it "The Analytical Engine".[8] Because Babbage did not have enough money and always evolved his design when he had an improved idea, he never built his Analytical Engine unit.As time went on, pcs were used more. People get uninterested easily doing the same thing over and over. Imagine spending your life writing things down on index credit cards, storing them, and then needing to go find them again. The U.S. Census Bureau in 1890 possessed hundreds of men and women doing just that. It had been expensive, and information took a long time. Then an engineer worked out steps to make machines do a lot of the task. Herman Hollerith invented a tabulating machine that could automatically accumulate information that the Census bureau gathered. The Computing Tabulating Recording Company (which later became IBM) made his machines. They leased the machines rather than selling them. Creators of machines had long helped their users understand and repair them, and CTR's tech support was especially good.Because of machines like this, new means of speaking with these machines were developed, and new types of machines were invented, and eventually the computer as we know it was created.

Analog and Digital Computers
In the first 50 percent of the 20th century, scientists began using computers, generally because scientists acquired a great deal of math to figure out and wanted to spend more of their own time thinking about knowledge questions rather than spending hours adding numbers collectively. For example, if they had to establish a rocket ship, they needed to do a lot of math to make sure the rocket worked well right. So they put together personal computers. These analog personal computers used analog circuits, which made them very difficult to program. Inside the 1930s, they invented digital computer systems, and soon made them simpler to program. However this is not the case as many consecutive tries have been made to bring arithmetic logic to l3.Analogue personal computers are mechanical or electronic devices which solve problems. some are used to regulate machines.
