MANAGEMENT INFORMATION SYSTEM ppt video online download

Definition
Your personal computer is a programmable digital camera designed to recognize data, perform prescribed mathematical and reasonable operations at broadband, and screen the results of these operations, all under the control of software. Mainframes, desktop and laptops, tablets and smartphones are some of the various types of computer systems. An electronic machine which helps in solving problems quickly and easily. It solves problems according to instructions given to it by the computer individual called programs or software. It really is an electronic machine(that uses binary digits) used in all field

Automation
Most humans have a problem 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 bear in mind where these were in a math problem. The other problem folks have is that they have to do the same problem over and over and once more. A cashier had to make change every day in her mind or with a piece of paper. That had taken a lot of time and made blunders. So, people made calculators that have those same things over and over. This part of computer background is named the "history of automated calculation," which really is a fancy expression for "the annals of machines which make it easy for me to do this same maths problem over and over without making mistakes."The abacus, the slip rule, the astrolabe and the Antikythera device (which schedules from about 150-100 BC) are examples of automated calculation machines.

Programming
People do not need a machine that could do a similar thing again and again. For instance, a music pack is a machine that performs the same music again and again. Some people wanted to have the ability to tell their machine to do different things. For example, they wanted to notify the music container that can be played different music each and every time. They wished to have the ability to program the music box- to order the music container to try out different music. This part of computer record is named the "history of programmable machines" which is a fancy phrase for "The annals of machines that I can order to do various things if I know how to speak their words."One of the first examples of this is built by Hero of Alexandria (c. 10-70 AD). He built a mechanical movie theater which performed a play enduring ten minutes and was run by a complex system of ropes and drums. These ropes and drums were the terms of the machine- they advised what the machine did and when. Some people argue that is the first programmable machine.Historians disagree on which early machines are "computer systems". Many say the "castle clock", an astronomical clock invented by Al-Jazari in 1206, is the first known programmable analog computer. The space of night and day could be modified every day in order to account for the changing measures of night and day over summer and winter. Some count up 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
At the end of the Middle Ages, people in Europe thought math and executive were more important. In 1623, Wilhelm Schickard made a mechanical calculator. Other Europeans made more calculators after him. These were not modern pcs because they could only add, subtract, and multiply- you cannot change what they performed to make them take action like play Tetris. As a result of this, we say these were not programmable. Now technicians use computers to create and plan.In 1801, Joseph Marie Jacquard used punched newspaper cards to inform his textile loom what kind of structure to weave. He could use punch cards to share the loom what to do, and he could change the punch credit cards, this means he could program the loom to weave the design he wanted. This implies the loom was programmable.Charles Babbage wanted to make an identical machine which could assess. He called it "The Analytical Engine".[8] Because Babbage did not have enough money and always altered his design when he had a much better idea, he never built his Analytical Engine unit.As time continued, computer systems were used more. People get bored stiff easily doing a similar thing again and again. Imagine spending your daily life writng down things on index credit cards, holding them, and then having to go find them again. The U.S. Census Bureau in 1890 possessed hundreds of people doing just that. It was expensive, and reviews took quite a while. Then an engineer worked out how to make machines do a lot of the task. Herman Hollerith invented a tabulating machine that could automatically add up information that the Census bureau gathered. The Processing Tabulating Recording Corporation (which later became IBM) made his machines. They leased the machines rather than selling them. Makers of machines had long helped their users understand and repair them, and CTR's technology support was especially good.Because of machines like this, new means of talking to these machines were invented, and new types of machines were created, and finally the computer as we know it was born.

Analog and Digital Computers
In the first 50 percent of the 20th century, scientists started out using computers, largely because scientists had a great deal of math to figure out and wished to spend more of their own time thinking about research questions rather than spending hours adding numbers jointly. For example, if they had to release a rocket ship, they had a need to do a whole lot of math to make sure the rocket functioned right. So they come up with pcs. These analog personal computers used analog circuits, which made them very hard to program. Within the 1930s, they developed digital pcs, and soon made them simpler to program. However this is false as many consecutive efforts have been designed to bring arithmetic reasoning to l3.Analogue computer systems are mechanical or electronic devices which solve problems. some are being used to regulate machines.
