Types of Information System: TPS, DSS Pyramid Diagram

Definition
A computer is a programmable electronic device designed to acknowledge data, perform prescribed mathematical and reasonable operations at high speed, and display the results of these businesses, all under the control of software. Mainframes, desktop and laptop computers, tablets and smartphones are a few of the various types of pcs. An electronic machine which helps in solving problems quickly and easily. It solves problems according to instructions given to it by the computer customer called programs or software. It is a digital machine(that uses binary digits) found in all field

Automation
Most humans have a problem with math. Showing this, try doing 584 x 3,220 in your mind. It is hard to keep in mind all the steps! People made tools to help them remember where these were in a mathematics problem. The other problem people have is that they have to do the same problem again and again and once more. A cashier was required to make change every day in her head or with a bit of paper. That had taken a lot of time and made flaws. So, people made calculators that have those same things over and over. This part of computer record is called the "history of automatic calculation," which is a fancy saying for "the annals of machines that make it easy for me to do this same maths problem again and again without making blunders."The abacus, the glide rule, the astrolabe and the Antikythera mechanism (which times from about 150-100 BC) are types of automated computation machines.

Programming
People do not need a machine that would do a similar thing over and over again. For instance, a music pack is a machine that plays the same music over and over again. Some people wished to have the ability to tell their machine to do different things. For example, they wished to inform the music field to learn different music each and every time. They wished to be able to program the music field- to order the music box to learn different music. This part of computer background is named the "history of programmable machines" which really is a fancy saying for "The annals of machines that I can order to do different things if I know how to speak their vocabulary."One of the first examples of this was built by Hero of Alexandria (c. 10-70 Advertisement). He built a mechanised movie theater which performed a play enduring ten minutes and was controlled by a complex system of ropes and drums. These ropes and drums were the terminology of the machine- they told what the device did so when. Some people dispute that is the first programmable machine.Historians disagree which early on machines are "personal computers". Many say the "castle clock", an astronomical clock developed by Al-Jazari in 1206, is the first known programmable analog computer. The distance of day and night could be tweaked every day to be able to account for the changing lengths of day and night throughout the year. Some matter this daily adjustment as computer programming.Others say the first computer was created by Charles Babbage. Ada Lovelace is known as to be the first programmer.

The Processing Era
By the end of the Middle Age groups, people in European countries thought math and engineering were more important. In 1623, Wilhelm Schickard made a mechanical calculator. Other Europeans made more calculators after him. These were not modern computers because they could only add, subtract, and increase- you could not change what they performed to make sure they are do something like play Tetris. Because of this, we say they were not programmable. Now designers use computers to create and plan.In 1801, Joseph Marie Jacquard used punched paper cards to share his textile loom what kind of structure to weave. He could use punch cards to share with the loom what to do, and he could change the punch cards, which means he could program the loom to weave the routine he wanted. This means the loom was programmable.Charles Babbage wanted to make a similar machine that can estimate. He called it "The Analytical Engine".[8] Because Babbage did not have enough money and always evolved his design when he had a better idea, he never built his Analytical Engine motor.As time continued, pcs were used more. People get weary easily doing the same thing over and over. Imagine spending your daily life writng down things on index credit cards, keeping them, and then having to go see them again. The U.S. Census Bureau in 1890 experienced hundreds of folks doing that. It was expensive, and accounts 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 accumulated. The Processing Tabulating Recording Corporation (which later became IBM) made his machines. They leased the machines instead of selling them. Producers of machines experienced long helped their users understand and repair them, and CTR's technical support was especially good.Because of machines such as this, new ways of speaking with these machines were created, and new types of machines were created, and eventually the computer as we realize it was born.

Analog and Digital Computers
Inside the first 1 / 2 of the 20th century, scientists started out using computers, mainly because scientists had a great deal of math to figure out and wished to spend more of their time thinking about science questions rather than expending hours adding numbers alongside one another. For example, if indeed they had to launch a rocket dispatch, they had a need to do a lot of math to be sure the rocket worked right. So they put together pcs. These analog personal computers used analog circuits, which made them very hard to program. Within the 1930s, they developed digital computer systems, and soon made them much easier to program. However this is false as many consecutive tries have been made to bring arithmetic reasoning to l3.Analogue pcs are mechanised or electronic devices which solve problems. some are used to regulate machines.
